Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. For the fiscal year ended April 30, 2024, the Fund’s portfolio turnover rate was 51% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock The following example is intended to help retail investors compare the cost of investing in the Fund with the cost of investing in other funds. It illustrates the hypothetical expenses that such investors would incur over various periods if they were to invest $10,000 in the Fund for the time periods indicated and then redeem all of the Shares at the end of those periods. This example assumes that the Fund provides a return of 5% a year and that operating expenses remain the same.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses an objective, rules-based methodology to implement a systematic trend-following strategy that directs exposure (i) 100% to the S&P 500® Index (the “S&P 500”), (ii) 50% to the S&P 500 and 50% to 3-Month US Treasury bills, or (iii) 100% to 3-Month US Treasury bills, depending on the relative performance of the S&P 500 and its 200-business day historical simple moving average (the “200-day moving average”). The calculation of the 200-day moving average for the S&P 500 is based on the total return version of the S&P 500 and reflects the reinvestment of dividends paid by the securities in the S&P 500. The Index is expected to be predominantly invested in the components of the S&P 500 over most short- and long-term periods and is only expected to invest in 3-Month US Treasury bills from time to time in response to adverse market conditions as defined by the “50/50 Indicator” and “T-Bill Indicator” below. The S&P 500 consists of approximately 500 leading U.S.-listed companies representing approximately 80% of the U.S. equity market capitalization.
The Index, and consequently the Fund, may stay in any of its three possible positions for an extended period of time. As described below, the Index will change its position based on the following indicators, and each change will become effective at the close of business on the first business day after the indicator for the change is triggered. The Index will be in a new position effective on the second business day.
Equity Indicator. When the S&P 500 closes above its 200-day moving average for five consecutive business days (the “Equity Indicator”), the exposure of the Index will be 100% to the S&P 500, effective at the close of business on the first business day following the date of the Equity Indicator. The Index will be in a new position effective on the second business day.
Once the Equity Indicator has been triggered, the exposure of the Index will next change to either be 50% to the S&P 500 and 50% to 3-Month US Treasury bills if the 50/50 Indicator (described below) is triggered or 100% to 3-Month US Treasury bills if both the 50/50 Indicator and the T-Bill Indicator (described below) are triggered simultaneously, effective at the close of business on the first business day following the date of the indicator(s). The Index will be in a new position effective on the second business day.
50/50 Indicator. When the S&P 500 closes below its 200-day moving average for five consecutive business days (the “50/50 Indicator”), the exposure of the Index will be 50% to the S&P 500 and 50% to 3-Month US Treasury bills, effective at the close of business on the first business day following the date of the 50/50 Indicator. The Index will be in a new position effective on the second business day. Following the effectiveness of the 50/50 Indicator, the exposure of the Index may be greater than or less than 50% with respect to the S&P 500 and 3-Month US Treasury bills depending on their respective performance until either the Equity Indicator or T-Bill Indicator (described below) is triggered.
Once the 50/50 Indicator has been triggered, the exposure of the Index will next change to either be 100% to the S&P 500 if the Equity Indicator is triggered or 100% to 3-Month US Treasury bills if the T-Bill Indicator (described below) is triggered, effective at the close of business on the first business day following the date of the indicator. The Index will be in a new position effective on the second business day.
T-Bill Indicator. When the S&P 500’s 200-day moving average closes lower than its value from five business days earlier (the “T-Bill Indicator”) and the 50/50 Indicator has been triggered, the exposure of the Index will be 100% to 3-Month US Treasury bills, effective at the close of business on the first business day following the date of the T-Bill Indicator. The Index will be in a new position effective on the second business day.
For example, if today is Wednesday and the S&P 500’s 200-day moving average closes lower than it did on the fifth preceding business day (Wednesday of the preceding week), the T-Bill Indicator is triggered. Unlike the operation of the Equity Indicator and 50/50 Indicator, the closing values on the days in between today and the fifth preceding business day do not affect whether the T-Bill Indicator has been triggered; rather, the T-Bill Indicator simply compares today’s closing value to the closing value five business days earlier. However, the Index will not move directly from 100% exposure to the S&P 500 to 100% exposure to 3-Month US Treasury bills unless the 50/50 Indicator was simultaneously triggered following the most recent triggering of the Equity Indicator.
Once the T-Bill Indicator has been triggered, the exposure of the Index will next change to be 100% to the S&P 500 if the Equity Indicator is triggered, effective at the close of business on the first business day following the date of the indicator. The Index will be in a new position effective on the second business day. Once the T-Bill Indicator has been triggered, the Index will not return to its 50/50 position unless the Equity Indicator is first triggered, followed by the 50/50 Indicator being triggered.
The Index aims to mitigate, to some extent, the volatility of the S&P 500 by tracking 3-Month US Treasury bills (instead of the S&P 500) when the S&P 500 is in a negative trend.
Special Indicator. In the event the S&P 500 closes 20% below its 200-day moving average, the Index will change exposures effective at the end of the following business day to be 50% to the S&P 500 and 50% to 3-Month US Treasury bills. If the Index exposure is 50% S&P 500 and 50% 3-Month U.S. Treasury Bills before the Special Indicator, no rebalance is needed. This new exposure will continue until the Equity Indicator is triggered.
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

Risk [Text Block] rr_RiskTextBlock ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.
Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market
conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Pacer Trendpilot US Large Cap ETF | Fixed Income Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.

Government Obligations Risk. The Fund may invest in securities issued by the U.S. government. There can be no guarantee that the United States will be able to meet its payment obligations with respect to such securities. Additionally, market prices and yields of securities supported by the full faith and credit of the U.S. government may decline or be negative for short or long periods of time.

Risk [Text Block] rr_RiskTextBlock
Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.
Pacer Trendpilot US Large Cap ETF | Passive Investment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Passive Investment Risk. The Fund is not actively managed and the Adviser would not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology. The Fund invests in securities included in the Index regardless of their investment merits. Other than in response to one of the triggers set forth above in accordance with the Index methodology, the Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.
Pacer Trendpilot US Large Cap ETF | Tracking Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index.
Pacer Trendpilot US Large Cap ETF | Trend Lag Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Trend Lag Risk. At least six consecutive trading days will elapse after the S&P 500 first drops below its historical 200-day simple moving average (or conversely, first moves above such average) before the Index will switch from tracking the S&P 500 to 3-Month US Treasury bills (or conversely, from 3-Month US Treasury bills to the S&P 500). As a result, if the S&P 500 is in an overall positive trend, the Index and consequently the Fund may be adversely affected by a downward trend and/or volatility in the S&P 500 for up to six consecutive trading days (or conversely, if the S&P 500 is in an overall negative trend, the Index and consequently the Fund may not benefit from an upward trend and/or volatility in the S&P 500 for up to six consecutive trading days). This lag will be shorter (one business day) under the Special Indicator. Accordingly, the methodology employed by the Index does not eliminate exposure to downward trends and/or volatility in the S&P 500 and does not provide immediate exposure to upward trends and/or volatility in the S&P 500.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses an objective, rules-based methodology to implement a systematic trend-following strategy that directs exposure (i) 100% to the S&P MidCap 400® Index (the “S&P MidCap 400”), (ii) 50% to the S&P MidCap 400 and 50% to 3-Month US Treasury bills, or (iii) 100% to 3-Month US Treasury bills, depending on the relative performance of the S&P MidCap 400 and its 200-business day historical simple moving average (the “200-day moving average”). The calculation of the 200-day moving average for the S&P MidCap 400 is based on the total return version of the S&P MidCap 400 and reflects the reinvestment of dividends paid by the securities in the S&P MidCap 400. The Index is expected to be predominantly invested in the components of the S&P MidCap 400 over most short- and long-term periods and is only expected to invest in 3-Month US Treasury bills from time to time in response to adverse market conditions as defined by the “50/50 Indicator” and “T-Bill Indicator” below. The S&P MidCap 400 measures the performance of mid-capitalization stocks in the United States.
The Index, and consequently the Fund, may stay in any of its three possible positions for an extended period of time. As described below, the Index will change its position based on the following indicators, and each change will become
effective at the close of business on the first business day after the indicator for the change is triggered. The Index will be in a new position effective on the second business day.
Equity Indicator. When the S&P MidCap 400 closes above its 200-day moving average for five consecutive business days (the “Equity Indicator”), the exposure of the Index will be 100% to the S&P MidCap 400, effective at the close of business on the first business day following the date of the Equity Indicator. The Index will be in a new position effective on the second business day.
Once the Equity Indicator has been triggered, the exposure of the Index will next change to either be 50% to the S&P MidCap 400 and 50% to 3-Month US Treasury bills if the 50/50 Indicator (described below) is triggered or 100% to 3-Month US Treasury bills if both the 50/50 Indicator and the T-Bill Indicator (described below) are triggered simultaneously, effective at the close of business on the first business day following the date of the indicator(s). The Index will be in a new position effective on the second business day.
50/50 Indicator. When the S&P MidCap 400 closes below its 200-day moving average for five consecutive business days (the “50/50 Indicator”), the exposure of the Index will be 50% to the S&P MidCap 400 and 50% to 3-Month US Treasury bills, effective at the close of business on the first business day following the date of the 50/50 Indicator. The Index will be in a new position effective on the second business day. Following the effectiveness of the 50/50 Indicator, the exposure of the Index may be greater than or less than 50% with respect to the S&P MidCap 400 and 3-Month US Treasury bills depending on their respective performance until either the Equity Indicator or T-Bill Indicator (described below) is triggered.
Once the 50/50 Indicator has been triggered, the exposure of the Index will next change to either be 100% to the S&P MidCap 400 if the Equity Indicator is triggered or 100% to 3-Month US Treasury bills if the T-Bill Indicator (described below) is triggered, effective at the close of business on the first business day following the date of the indicator.
T-Bill Indicator. When the S&P MidCap 400’s 200-day moving average closes lower than its value from five business days earlier (the “T-Bill Indicator”) and the 50/50 Indicator has been triggered, the exposure of the Index will be 100% to 3-Month US Treasury bills, effective at the close of business on the first business day following the date of the T-Bill Indicator. The Index will be in a new position effective on the second business day.
For example, if today is Wednesday and the S&P MidCap 400’s 200-day moving average closes lower than it did on the fifth preceding business day (Wednesday of the preceding week), the T-Bill Indicator is triggered. Unlike the operation of the Equity Indicator and 50/50 Indicator, the closing values on the days in between today and the fifth preceding business day do not affect whether the T-Bill Indicator has been triggered; rather, the T-Bill Indicator simply compares today’s closing value to the closing value five business days earlier. However, the Index will not move directly from 100% exposure to the S&P MidCap 400 to 100% exposure to 3-Month US Treasury bills unless the 50/50 Indicator was first triggered following the most recent triggering of the Equity Indicator.
Once the T-Bill Indicator has been triggered, the exposure of the Index will next change to be 100% to the S&P MidCap 400 if the Equity Indicator is triggered, effective at the close of business on the first business day following the date of the indicator. The Index will be in a new position effective on the second business day. Once the T-Bill Indicator has been triggered, the Index will not return to its 50/50 position unless the Equity Indicator is simultaneously triggered, followed by the 50/50 Indicator being triggered.
The Index aims to mitigate, to some extent, the volatility of the S&P MidCap 400 by tracking 3-Month US Treasury bills (instead of the S&P MidCap 400) when the S&P MidCap 400 is in a negative trend.
Special Indicator. In the event the S&P MidCap 400 closes 20% below its 200-day moving average, the Index will change exposures effective at the end of the following business day to be 50% to the S&P MidCap 400 and 50% to 3-Month US Treasury bills. If the Index exposure is 50% S&P MidCap 400 and 50% 3-Month U.S. Treasury Bills before the Special Indicator, no rebalance is needed. This new exposure will continue until the Equity Indicator is triggered.
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.

Risk [Text Block] rr_RiskTextBlock
Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

Risk [Text Block] rr_RiskTextBlock
ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.
Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Pacer Trendpilot US Mid Cap ETF | Fixed Income Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.

Government Obligations Risk. The Fund may invest in securities issued by the U.S. government. There can be no guarantee that the United States will be able to meet its payment obligations with respect to such securities. Additionally, market prices and yields of securities supported by the full faith and credit of the U.S. government may decline or be negative for short or long periods of time.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
High Portfolio Turnover Risk. At times, the Fund may have a portfolio turnover rate substantially greater than 100%. A high portfolio turnover rate would result in correspondingly greater transaction expenses, including brokerage commissions, dealer mark ups and other transaction costs, on the sale of securities and on reinvestment in other securities and may result in reduced performance and the distribution to shareholders of additional capital gains for tax purposes. These factors may negatively affect the Fund’s performance.
Pacer Trendpilot US Mid Cap ETF | Mid-Capitalization Investing Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Mid-Capitalization Investing Risk. The Fund may invest in the securities of mid-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of mid-capitalization companies underperform securities of other capitalization ranges or the market as a whole. Securities of smaller companies trade in smaller volumes and are often more vulnerable to market volatility than securities of larger companies.
Pacer Trendpilot US Mid Cap ETF | Passive Investment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Passive Investment Risk. The Fund is not actively managed and the Adviser would not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology. The Fund invests in securities included in the Index regardless of their investment merits. Other than in response to one of the triggers set forth above in accordance with the Index methodology, the Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.
Pacer Trendpilot US Mid Cap ETF | Tracking Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index.
Pacer Trendpilot US Mid Cap ETF | Trend Lag Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Trend Lag Risk. At least six consecutive trading days will elapse after the S&P MidCap 400 first drops below its historical 200-day simple moving average (or conversely, first moves above such average) before the Index will switch from tracking the S&P MidCap 400 to 3-Month US Treasury bills (or conversely, from 3-Month US Treasury bills to the S&P MidCap 400). As a result, if the S&P MidCap 400 is in an overall positive trend, the Index and consequently the Fund may be adversely affected by a downward trend and/or volatility in the S&P MidCap 400 for up to six consecutive trading days (or conversely, if the S&P MidCap 400 is in an overall negative trend, the Index and consequently the Fund may not benefit from an upward trend and/or volatility in the S&P MidCap 400 for up to six consecutive trading days). This lag will be shorter (one business day) under the Special Indicator. Accordingly, the methodology employed by the Index does not eliminate exposure to downward trends and/or volatility in the S&P MidCap 400 and does not provide immediate exposure to upward trends and/or volatility in the S&P MidCap 400.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses an objective, rules-based methodology to implement a systematic trend-following strategy that directs exposure (i) 100% to the NASDAQ-100® Index (the “NASDAQ-100”), (ii) 50% to the NASDAQ-100 and 50% to 3-Month US Treasury bills, or (iii) 100% to 3-Month US Treasury bills, depending on the relative performance of the NASDAQ-100 and its 200-business day historical simple moving average (the “200-day moving average”). The calculation of the 200-day moving average for the NASDAQ-100 is based on the total return version of the NASDAQ-100 and reflects the reinvestment of dividends paid by the securities in the NASDAQ-100. The Index is expected to be predominantly invested in the components of the NASDAQ-100 over most short- and long-term periods and is only expected to invest in 3-Month US Treasury bills from time to time in response to adverse market conditions as defined by the “50/50 Indicator” and “T-Bill Indicator” below.
The NASDAQ-100 Index includes approximately 100 of the largest non-financial securities listed on The NASDAQ Stock Market based on market capitalization. The NASDAQ-100 Index comprises securities of companies across major industry groups, including computer, biotechnology, healthcare, telecommunications and transportation. However, it does not contain securities of financial companies, including investment companies. The NASDAQ-100 Index was developed
by NASDAQ OMX. There is no minimum market capitalization requirement for inclusion in the NASDAQ-100 Index. Inclusion is determined based on the top 100 largest issuers based on market capitalization meeting all other eligibility requirements. As of June 30, 2024, the range of market capitalizations of companies in the NASDAQ-100 Index was approximately $10.4 billion to $3.3 trillion.
The Index, and consequently the Fund, may stay in any of its three possible positions for an extended period of time. As described below, the Index will change its position based on the following indicators, and each change will become effective on the second business day after the indicator for the change is triggered. The Index will be in a new position effective at the close of business on the first business day.
Equity Indicator. When the NASDAQ-100 closes above its 200-day moving average for five consecutive business days (the “Equity Indicator”), the exposure of the Index will be 100% to the NASDAQ-100, effective at the close of business on the first business day following the date of the Equity Indicator. The Index will be in a new position effective on the second business day.
Once the Equity Indicator has been triggered, the exposure of the Index will next change to either be 50% to the NASDAQ-100 and 50% to 3-Month US Treasury bills if the 50/50 Indicator (described below) is triggered or 100% to 3-Month US Treasury bills if both the 50/50 Indicator and the T-Bill Indicator (described below) are triggered simultaneously, effective on the second business day following the date of the indicator(s). The Index will be in a new position effective at the close of business on the first business day.
50/50 Indicator. When the NASDAQ-100 closes below its 200-day moving average for five consecutive business days (the “50/50 Indicator”) and the 50/50 Indicator has been triggered, the exposure of the Index will be 50% to the NASDAQ-100 and 50% to 3-Month US Treasury bills, effective at the close of business on the first business day following the date of the 50/50 Indicator. The Index will be in a new position effective on the second business day. Following the effectiveness of the 50/50 Indicator, the exposure of the Index may be greater than or less than 50% with respect to the NASDAQ-100 and 3-Month US Treasury bills depending on their respective performance until either the Equity Indicator or T-Bill Indicator (described below) is triggered.
Once the 50/50 Indicator has been triggered, the exposure of the Index will next change to either be 100% to the NASDAQ-100 if the Equity Indicator is triggered or 100% to 3-Month US Treasury bills if the T-Bill Indicator (described below) is triggered, effective at the close of business on the first business day following the date of the indicator(s). The Index will be in a new position effective on the second business day.
T-Bill Indicator. When the NASDAQ-100’s 200-day moving average closes lower than its value from five business days earlier (the “T-Bill Indicator”), the exposure of the Index will be 100% to 3-Month US Treasury bills, effective at the close of business on the first business day following the date of the T-Bill Indicator. The Index will be in a new position effective on the second business day.
For example, if today is Wednesday and the NASDAQ-100’s 200-day moving average closes lower than it did on the fifth preceding business day (Wednesday of the preceding week), the T-Bill Indicator is triggered. Unlike the operation of the Equity Indicator and 50/50 Indicator, the closing values on the days in between today and the fifth preceding business day do not affect whether the T-Bill Indicator has been triggered; rather, the T-Bill Indicator simply compares today’s closing value to the closing value five business days earlier. However, the Index will not move directly from 100% exposure to the NASDAQ-100 to 100% exposure to 3-Month US Treasury bills unless the 50/50 Indicator was first triggered following the most recent triggering of the Equity Indicator.
Once the T-Bill Indicator has been triggered, the exposure of the Index will next change to be 100% to the NASDAQ-100 if the Equity Indicator is triggered, effective at the close of business on the first business day following the date of the indicator. The Index will be in a new position effective on the second business day. Once the T-Bill Indicator has been triggered, the Index will not return to its 50/50 position unless the Equity Indicator is simultaneously triggered, followed by the 50/50 Indicator being triggered.
The Index aims to mitigate, to some extent, the volatility of the NASDAQ-100 by tracking 3-Month US Treasury bills (instead of the NASDAQ-100) when the NASDAQ-100 is in a negative trend.
Special Indicator. In the event the NASDAQ-100 closes 20% below its 200-day moving average, the Index will change exposures effective at the end of the following business day to be 50% to the NASDAQ-100 and 50% to 3-Month US Treasury bills. If the Index exposure is 50% NASDAQ-100 and 50% 3-Month U.S. Treasury Bills before the Special Indicator, no rebalance is needed. This new exposure will continue until the Equity Indicator is triggered.
The Fund’s Investment Strategy
The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.

Risk [Text Block] rr_RiskTextBlock Calculation Methodology Risk. The Index relies directly or indirectly on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund, the Index Provider, or the Adviser can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included components or a correct valuation of securities, nor can they guarantee the availability or timeliness of the production of the Index.
Pacer Trendpilot 100 ETF | Concentration Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Concentration Risk. If the Index concentrates in an industry or group of industries, the Fund’s investments may be concentrated accordingly. In such event, the value of the Fund’s shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. In addition, at times, an industry or group of industries in which the Fund is concentrated may be out of favor and underperform other industries or groups of industries.
Pacer Trendpilot 100 ETF | Equity Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.
Pacer Trendpilot 100 ETF | ETF Risks Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.
Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as The Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Risk [Text Block] rr_RiskTextBlock
Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.

Government Obligations Risk. The Fund may invest in securities issued by the U.S. government. There can be no guarantee that the United States will be able to meet its payment obligations with respect to such securities. Additionally, market prices and yields of securities supported by the full faith and credit of the U.S. government may decline or be negative for short or long periods of time.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.
Pacer Trendpilot 100 ETF | Risk Nondiversified Status [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
Pacer Trendpilot 100 ETF | Passive Investment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Passive Investment Risk. The Fund is not actively managed and the Adviser would not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology. The Fund invests in securities included in the Index regardless of their investment merits. Other than in response to one of the triggers set forth above in accordance with the Index methodology, the Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.
Pacer Trendpilot 100 ETF | Sector Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.
Communications Services Sector Risk. The Fund is generally expected to invest significantly in companies in the communications services sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Communications services companies are subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may adversely affect the business of the such
companies. Companies in the communications services sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications (including with 5G and other technologies), product compatibility, consumer preferences, rapid product obsolescence, and research and development of new products. Technological innovations may make the products and services of such companies obsolete.
Consumer Discretionary Sector Risk. The Fund may invest in companies in the consumer discretionary sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.
Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index.
Pacer Trendpilot 100 ETF | Trend Lag Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Trend Lag Risk. At least six consecutive trading days will elapse after the NASDAQ-100 first drops below its historical 200-day simple moving average (or conversely, first moves above such average) before the Index will switch from tracking the NASDAQ-100 to 3-Month US Treasury bills (or conversely, from 3-Month US Treasury bills to the NASDAQ-100). As a result, if the NASDAQ-100 is in an overall positive trend, the Index and consequently the Fund may be adversely affected by a downward trend and/or volatility in the NASDAQ-100 for up to six consecutive trading days (or conversely, if the NASDAQ-100 is in an overall negative trend, the Index and consequently the Fund may not benefit from an upward trend and/or volatility in the NASDAQ-100 for up to six consecutive trading days). This lag will be shorter (one business day) under the Special Indicator. Accordingly, the methodology employed by the Index does not eliminate exposure to downward trends and/or volatility in the NASDAQ-100 and does not provide immediate exposure to upward trends and/or volatility in the NASDAQ-100.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. For the fiscal year ended April 30, 2024, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 58.00%
Expenses Not Correlated to Ratio Due to Acquired Fund Fees [Text] rr_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees Acquired Fund Fees and Expenses (“AFFE”) are the indirect costs of investing in other investment companies. Total Annual Fund Operating Expenses do not correlate to the expense ratios in the Fund’s Financial Highlights because the Financial Highlights include only the direct operating expenses incurred by the Fund and exclude AFFE.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group, an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses an objective, rules-based methodology to implement a systematic trend-following strategy that directs exposure (i) 100% to the S&P Developed Ex-U.S. LargeCap Index, (ii) 50% to the S&P Developed Ex-U.S. LargeCap Index and 50% to 3-Month US Treasury bills, or (iii) 100% to 3-Month US Treasury bills, depending on the relative performance of the S&P Developed Ex-U.S. LargeCap Index and its 200-business day historical simple moving average (the “200-day moving average”). The calculation of the 200-day moving average for the S&P Developed Ex-U.S. LargeCap Index is based on the total return version of the S&P Developed Ex-U.S. LargeCap Local Currency Index and reflects the reinvestment of dividends paid by the securities in the S&P Developed Ex-U.S. LargeCap Index. The Index is expected to be predominantly invested in the components of the S&P Developed Ex-U.S. LargeCap Index over most short- and long-term periods and is only expected to invest in 3-Month US Treasury bills from time to time in response to adverse market conditions as defined by the “50/50 Indicator” and “T-Bill Indicator” below.
The S&P Developed Ex-U.S. LargeCap Index is a rules-based, float-adjusted, market capitalization-weighted index comprised of large-capitalization stocks providing coverage of the developed markets excluding the United States. The S&P Developed Ex-U.S. LargeCap Index is a subset of the S&P Global BMI, a comprehensive, rules-based index measuring global stock market performance.
The Index, and consequently the Fund, may stay in any of its three possible positions for an extended period of time. As described below, the Index will change its position based on the following indicators, and each change will become effective on the second business day after the indicator for the change is triggered.
As of June 30, 2024, the Index was entirely invested in the S&P Developed Ex-U.S. LargeCap Index constituents.
Equity Indicator. When the S&P Developed Ex-U.S. LargeCap Index closes above its 200-day moving average for five consecutive business days (the “Equity Indicator”), the exposure of the Index will be 100% to the S&P Developed Ex-U.S. LargeCap Index, effective on the second business day following the date of the Equity Indicator.
Once the Equity Indicator has been triggered, the exposure of the Index will next change to either be 50% to the S&P Developed Ex-U.S. LargeCap Index and 50% to 3-Month US Treasury bills if the 50/50 Indicator (described below) is triggered or 100% to 3-Month US Treasury bills if both the 50/50 Indicator and the T-Bill Indicator (described below) are triggered simultaneously, effective on the second business day following the date of the indicator(s).
50/50 Indicator. When the S&P Developed Ex-U.S. LargeCap Index closes below its 200-day moving average for five consecutive business days (the “50/50 Indicator”), the exposure of the Index will be 50% to the S&P Developed Ex-U.S. LargeCap Index and 50% to 3-Month US Treasury bills, effective on the second business day following the date of the 50/50 Indicator. Following the effectiveness of the 50/50 Indicator, the exposure of the Index may be greater than or less than 50% with respect to the S&P Developed Ex-U.S. LargeCap Index and 3-Month US Treasury bills depending on their respective performance until either the Equity Indicator or T-Bill Indicator (described below) is triggered.
Once the 50/50 Indicator has been triggered, the exposure of the Index will next change to either be 100% to the S&P Developed Ex-U.S. LargeCap Index if the Equity Indicator is triggered or 100% to 3-Month US Treasury bills if the T-Bill Indicator (described below) is triggered, effective on the second business day following the date of the indicator.
T-Bill Indicator. When the S&P Developed Ex-U.S. LargeCap Index’s 200-day moving average closes lower than its value from five business days earlier (the “T-Bill Indicator”), the exposure of the Index will be 100% to 3-Month US Treasury bills, effective on the second business day following the date of the T-Bill Indicator.
For example, if today is Wednesday and the S&P Developed Ex-U.S. LargeCap Index’s 200-day moving average closes lower than it did on the fifth preceding business day (Wednesday of the preceding week), the T-Bill Indicator is triggered. Unlike the operation of the Equity Indicator and 50/50 Indicator, the closing values on the days in between today and the fifth preceding business day do not affect whether the T-Bill Indicator has been triggered; rather, the T-Bill Indicator simply compares today’s closing value to the closing value five business days earlier. However, the Index will not move directly from 100% exposure to the S&P Developed Ex-U.S. LargeCap Index to 100% exposure to 3-Month US Treasury bills unless the 50/50 Indicator was simultaneously triggered following the most recent triggering of the Equity Indicator.
Once the T-Bill Indicator has been triggered, the exposure of the Index will next change to be 100% to the S&P Developed Ex-U.S. LargeCap Index if the Equity Indicator is triggered, effective on the second business day following the date of the indicator. Once the T-Bill Indicator has been triggered, the Index will not return to its 50/50 position unless the Equity Indicator is first triggered, followed by the 50/50 Indicator being triggered.
The Index aims to mitigate, to some extent, the volatility of the S&P Developed Ex-U.S. LargeCap Index by tracking 3-Month US Treasury bills (instead of the S&P Developed Ex-U.S. LargeCap Index) when the S&P Developed Ex-U.S. LargeCap Index is in a negative trend.
Special Indicator. In the event the S&P Developed Ex-U.S. LargeCap Index closes 20% below its 200-day moving average, the Index will change exposures effective at the end of the following business day to be 50% to the S&P Developed Ex-U.S. LargeCap Index and 50% to 3-Month US Treasury bills. If the Index exposure is 50% Developed Ex-U.S. LargeCap Index and 50% 3-Month U.S. Treasury Bills before the Special Indicator, no rebalance is needed. This new exposure will continue until the Equity Indicator is triggered.
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts). The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better. The Fund’s assets may include investments denominated in non-U.S. currencies.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.
At times, the Fund may have a portfolio turnover rate substantially greater than 100%.

Risk [Text Block] rr_RiskTextBlock
Currency Exchange Rate Risk. The Fund’s assets may include investments denominated in non-U.S. currencies, such as the euro, or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
Pacer Trendpilot International ETF | Equity Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:
Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.
Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium)
or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.
Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Risk [Text Block] rr_RiskTextBlock
Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.
Pacer Trendpilot International ETF | Foreign Securities Risk Member

Risk [Text Block] rr_RiskTextBlock
Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.
Pacer Trendpilot International ETF | Geographic Concentration Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Geographic Concentration Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region.
Risks Related to Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities. Japan’s economic growth rate has remained relatively low for an extended period of time and it may remain low in the future. In addition, Japan is subject to the risk of natural disasters, such as earthquakes, volcanoes, typhoons and tsunamis. Additionally, decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosure rates may have an adverse impact on the economy of Japan. Japan also has few natural resources, and any fluctuation or shortage in the commodity markets could have a negative impact on Japanese securities.
Risks Related to Investing in Western Europe. Most developed countries in Western Europe are members of the European Union (“EU”), and many are also members of the European Monetary Union (EMU), which requires compliance with restrictions on inflation rates, deficits, and debt levels. Unemployment in certain European nations is historically high and several countries face significant debt problems. These conditions can significantly affect every country in Europe. The euro is the official currency of the EU. Funds that invest in Europe may have significant exposure to the euro and events affecting the euro. Recent market events affecting several of the EU member countries have adversely affected the sovereign debt issued by those countries, and ultimately may lead to a decline in the value of the euro. A significant decline in the value of the euro may produce unpredictable effects on trade and commerce generally and could lead to increased volatility in financial markets worldwide.
The UK’s departure from the EU (referred to as “Brexit”) continues to cause significant uncertainty and may adversely impact the financial results and operations of various European companies and economies. The effects of Brexit will largely depend on any agreements the UK makes to retain access to EU markets. Brexit may result in legal and tax uncertainty and divergent national laws and regulations as the UK determines which EU laws to replace or replicate. The UK may be less stable than it has been in recent years and investments in the UK may be more volatile. Additionally, Brexit could lead to global economic uncertainty and result in significant volatility in
the global stock markets and currency exchange rate fluctuations. Any of these effects of Brexit, and other consequences that are difficult to predict at this time, could adversely affect the value of the Fund’s investments..

High Portfolio Turnover Risk. At times, the Fund may have a portfolio turnover rate substantially greater than 100%. A high portfolio turnover rate would result in correspondingly greater transaction expenses, including brokerage commissions, dealer mark ups and other transaction costs, on the sale of securities and on reinvestment in other securities and may result in reduced performance and the distribution to shareholders of additional capital gains for tax purposes. These factors may negatively affect the Fund’s performance.

Mid-Capitalization Investing Risk. The Fund may invest in the securities of mid-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of mid-capitalization companies underperform securities of other capitalization ranges or the market as a whole. Securities of smaller companies trade in smaller volumes and are often more vulnerable to market volatility than securities of larger companies.

There is also the risk that the Fund may suffer losses due to the investment practices of the underlying funds. When the Fund invests in other investment companies, the Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by such investment companies. Investments in ETFs are also subject to the “ETF Risks” described above.

Passive Investment Risk. The Fund is not actively managed and the Adviser would not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology. The Fund invests in securities included in the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.
Pacer Trendpilot International ETF | Tracking Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. To the extent the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

At least six consecutive trading days will elapse after the S&P Developed Ex-U.S. LargeCap Index first drops below its historical 200-day simple moving average (or conversely, first moves above such average) before the Index will switch from tracking the S&P Developed Ex-U.S. LargeCap Index to 3-Month US Treasury bills (or conversely, from 3-Month US Treasury bills to the S&P Developed Ex-U.S. LargeCap Index ). As a result, if the S&P Developed Ex-U.S. LargeCap Index is in an overall positive trend, the Index and consequently the Fund may be adversely affected by a downward trend and/or volatility in the S&P Developed Ex-U.S. LargeCap Index for up to six consecutive trading days (or conversely, if the S&P Developed Ex-U.S. LargeCap Index is in an overall negative trend, the Index and consequently the Fund may not benefit from an upward trend and/or volatility in the S&P Developed Ex-U.S. LargeCap Index for up to six consecutive trading days). This lag will be shorter (one business day) under the Special Indicator. Accordingly, the methodology employed by the Index does not eliminate exposure to downward trends and/or volatility in the S&P Developed Ex-U.S. LargeCap Index or provide immediate exposure to upward trends and/or volatility in the S&P Developed Ex-U.S. LargeCap Index.
