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. Because the Fund is newly organized, portfolio turnover information is not yet available.

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” or “IDG”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”). Solactive AG serves as the calculation agent for the Index.
Solactive Pacer US Cash Cows Bond Index
The Solactive Pacer US Cash Cows Bond Index is a rules-based index that tracks the performance of corporate bonds issued in the United States by certain companies currently and previously represented in the Pacer US Cash Cows 100 Index and/or the Pacer US Large Cap Cash Cows Growth Leaders Index. The Pacer US Cash Cows 100 Index is a rules-based, strategy driven index that aims to provide capital appreciation over time by screening the Russell 1000 for the top 100 companies based on free cash flow yield. The Pacer US Large Cap Cash Cows Growth Leaders Index is a rules-based, strategy driven index that aims to provide capital appreciation over time by screening the Russell 1000 Index for the top 100 companies based on free cash flow margin. Companies with above average free cash flow margins and free cash flow yield are commonly referred to as “cash cows.”
The Index seeks to produce an optimized representation of U.S. dollar-denominated corporate bonds from companies within the aforementioned indices over the four most recent calendar quarters. From this universe, an initial screen is performed to ensure that all bonds are: US Dollar-denominated, have a time to maturity greater than 1 year regardless of optionality, have a time since issuance of less than 10 years, have a remaining par amount greater than $500 million, are rated by at least one of the following credit ratings agencies: Fitch Ratings, Moody’s Investor Service, or S&P Global Ratings.
Free Cash Flow (FCF): A company’s cash flow from operations minus capital expenditures.
Sales: The value of what a company sold to its customers during a given period; also known as revenue.
Free Cash Flow Margin: FCF / Sales
Enterprise Value (EV): A company’s market capitalization plus its debt and minus its cash and cash equivalents.
Free Cash Flow Yield: FCF / EV
Bonds rated lower than single B by any of the above credit ratings agencies are excluded. Individual bonds are then selected utilizing an optimization process to maximize the overall yield within the bounds of portfolio-level duration, sector, and credit quality constraints. The Index seeks to improve the portfolio’s yield while maintaining similar duration and sector exposures compared to traditional U.S. corporate bond indices. The Index utilizes an equal weighting scheme with a 4% limit on each issuer and 1% per bond.
The Index is reconstituted on an annual basis at the end of each September and rebalanced at the end of each calendar month. At each monthly maintenance rebalance, index constituents are added or deleted based on such criteria.
The Fund’s Investment Strategy
Under normal circumstances, the Fund will seek to invest at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) in U.S. bonds (i.e., 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.
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single issuer or small number of issuers than diversified funds.

▪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.

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.

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.
◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.
◦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 US Cash Cows Bond 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.
◦Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income.
◦Credit Risk. Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of an investment in that issuer.
◦Event Risk. Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly.
◦Extension Risk. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall.
◦Interest Rate 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. Changes in government intervention may have adverse effects on investments, volatility, and illiquidity in debt markets.
◦Prepayment Risk. When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the proceeds may have to be invested in securities with lower yields.

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.
Pacer US Cash Cows Bond ETF | High Yield Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock High Yield Risk. High yield debt obligations (commonly known as “junk bonds”) are speculative investments and entail greater risk of loss of principal than securities and loans that are investment grade rated because of their greater exposure to credit risk. The high yield market at times is subject to substantial volatility and high yield debt obligations may be less liquid than higher quality securities. As a result, the value of the Fund may be subject to greater volatility than other funds, and the Fund may be exposed to greater tracking risk (described below) than other funds.

Risk [Text Block] rr_RiskTextBlock Management Risk. To the extent the Fund uses a representative sampling strategy to obtain exposure to the Index, the Fund’s ability to track the performance of the Index will be contingent on the ability of the Fund’s sub-adviser to identify a subset of Index components whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Index as a whole.

Risk [Text Block] rr_RiskTextBlock New Fund Risk. The Fund is new with no operating history.

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 US Cash Cows Bond 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 Sub-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 US Cash Cows Bond 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.

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 Solactive AG (the “Index Provider”). J.H. Whitney Data Services LLC (“J.H. Whitney”) is responsible for selection of the Index components in accordance with the Index methodology.
Solactive Whitney Future of Warfare Index
The Index is a rules-based index that intends to track companies that support critical emerging defense technologies across the U.S. and its allies. Companies are selected based on affiliation with defense-related modernization priorities, their geostrategic risk rating score and the size of current contracts with the U.S. Department of Defense (“DOD”). The industry affiliation maps designated defense technology priorities to granular industry classifications, and the geostrategic risk rating score measures entanglement in risky countries, from a North Atlantic Treaty Organization (“NATO”) perspective. The result is a diversified constituent list of companies that are expected to produce technologies that will shape defense programs and capabilities, while limiting geopolitical risk from sanctions, trade, and conflict.
Construction of the Index begins with a universe of the component securities of the Solactive GBS Developed Markets Large & Mid Cap USD Index. The Solactive GBS Developed Markets Large & Mid Cap USD Index intends to track the performance of the large and mid cap segment covering approximately the largest 85% of the free-float market capitalization in the developed markets.
Securities from the Index universe are next evaluated based on risk-related criteria to determine an evaluation score of low, neutral and high, based on their activities in “high-risk,” “neutral” or “NATO” countries. High-risk countries include those that face increased risk from sanctions, trade and conflict, and are based on a risk review of the Annual Report of the Secretary General of NATO, as published by NATO. As of the date of this Prospectus, high-risk countries included China, Russia, North Korea and Iran. NATO countries are all member states of NATO. Neutral countries are all other countries not in the high-risk or NATO categories. Securities from companies that are assigned a sufficiently high combined score and are active in Critical Technology Defense Sectors, as defined and made publicly-available by the Office of the Under Secretary of Defense for Research and Engineering of the DOD, are selected for inclusion in the Index. Companies not active in the Critical Technology Defense Sectors are removed from the investable universe. As of the date of this Prospectus, Critical Technology Defense Sectors included: quantum science, future generation wireless technology, advanced materials, trusted artificial intelligence (“AI”) and autonomy, integrated network systems of systems, microelectrics, space technology, advanced computing and software, human-machine interfaces, directed energy, hypersonics and integrated sensing and cyber. Companies without any active contracts with the DOD for the current fiscal year are also excluded from the Index.
The risk-related criteria used to determine the evaluation score include:
•Ownership by Country: This risk component focuses on the location of the relevant company’s shareholders. Shareholders have significant influence over operations and management of a company, so any hostile actions at the shareholder level could pose a threat to the overall value or ability for the company to deliver innovation.
•Country Incorporation: This risk component focuses on where the relevant company is incorporated. Where a company is incorporated may have significance relative to its resilience in the face of geopolitical upheavals. Companies incorporated in a NATO country are likely to be more resilient to evolving geopolitical risks.
•Geographic Revenue: This risk component focuses on whether the relevant company is dependent on revenue streams from high-risk countries.
•Geographic Assets: This risk component focuses on whether the relevant company owns assets, or makes capital expenditures, that are concentrated in high-risk countries.
•Customers: This risk component focuses on the concentration (geographic and otherwise) of the relevant company’s customers. Resilient companies have a diversified customer base. Non-resilient companies are dependent on a small group of customers or have a large concentration of customers in high-risk countries.
•Suppliers: This risk component focuses on the concentration (geographic and otherwise) of the relevant company’s suppliers. Resilient companies have a diversified group of suppliers. Non-resilient companies are dependent on a small group of suppliers or have a large concentration of suppliers in high-risk countries.
•Board Memberships: This risk component focuses on risks posed by the composition of the relevant company’s board of Directors. The board of directors is responsible for the long-term direction and outlook of the company. Companies with board members who are also members of other resilient companies are scored high. Companies with board members who also serve on boards of companies in high-risk countries are scored low.
•Joint Ventures: This risk component focuses on risks posed by the relevant company’s participation in joint ventures. Joint ventures pose a risk of technology transfer that could result in loss by a participant of future market share from a new competitor. Because this risk causes a company to be deemed not resilient for the long-term purposes of government spending, companies that participate in joint ventures in high-risk countries, or with companies that are located in high-risk countries, are scored low.
•Strategic Alliances: This risk component focuses on risks posed by the relevant company’s participation in strategic alliances. Strategic alliances pose a risk of technology transfer that could result in loss by a participant of future market share from a new competitor. Because this risk causes a company to be deemed not resilient for the
long-term purposes of government spending, companies that participate in such alliances in high-risk countries, or with companies that are located in high-risk countries, are scored low.
•SAM Exclusion List: This risk component focuses on whether the relevant company appears on the System for Award Management (“SAM”) exclusion list. SAM is a publicly-available federal procurement database maintained by the U.S. General Services Administration, through which all entities that do business with the U.S. government must be registered. The SAM exclusion list is created to deny government contracts to entities that have engaged in negative activities such as contract non-fulfillment, being agents of a foreign government, or participating in other illicit and/or negligent activities. If a company appears on the SAM exclusion list, it is assigned a low score.
Each component security of the Index is assigned a weight based on the respective companies defense spending weight, with a cap of 7.5% and floor of 0.5%. The defense spending data is based on the current fiscal year DOD contract revenues as publicly reported by SAM. Defense spending data is calculated by J.H. Whitney and Index weights are calculated by Solactive. The composition and weighting of the Index will be revised by J.H. Whitney and Solactive, respectively, on the last Thursday of January, April, July and October (each, a “Selection Day”), and the Index is rebalanced after the close of business on the tenth day following the Selection Day.
The Fund’s Investment Strategy
Under normal circumstances, the Fund will seek to invest at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) in securities of companies that support critical emerging defense technologies across the U.S. and its allies (i.e., 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.
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. The Index, and consequently the Fund, is expected to have significant exposures to companies in the Information Technology Sector. In addition, the Index may have significant exposure to one or more countries at any given time. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single issuer or small number of issuers than diversified funds.

Pacer Solactive Whitney Future of Warfare ETF | Aerospace And Defense Industry Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock ▪Aerospace and Defense Industry Risk. The aerospace and defense industry may be significantly affected by government aerospace and defense regulation, spending policies, and geopolitical stability because companies involved in this industry rely to a significant extent on U.S. (and other) government demand for their products and services. The financial condition of and investor interest in Aerospace and Defense Companies will be negatively influenced by governmental defense spending policies that, outside the occurrence of certain events, such as terrorist attacks, war, and other geopolitical events, are typically under pressure from efforts to control the U.S. (and other) government budgets. The industry’s reliance on the successful development and implementation of new defense and aerospace technologies may result in limited product lines, markets, financial resources, customers, or personnel, all of which may have an adverse effect on profit margins. Products and technologies may face obsolescence due to rapid technological developments and frequent new product introduction, and as such, companies may face unpredictable changes in growth rates, competition for the services of qualified personnel and competition from foreign competitors with lower production costs.
Pacer Solactive Whitney Future of Warfare ETF | Artificial Intelligence Companies Risk Member

Risk [Text Block] rr_RiskTextBlock Artificial Intelligence Companies Risk. AI technologies typically face intense competition and potentially rapid product obsolescence. AI is heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. There can be no assurance these companies will be able to successfully protect their intellectual property to prevent the misappropriation of their technology, or that competitors will not develop technology that is substantially similar or superior. AI companies typically engage in significant amounts of spending on research and development, as well as mergers and acquisitions, and there is no guarantee that the products or services produced by these companies will be successful. AI companies are potential targets for cyberattacks, which can have a materially adverse impact on the performance of these companies. In addition, AI technology could face increasing regulatory scrutiny in the future, which may limit the development of this technology and impede the growth of companies that develop and/or utilize this technology.

Risk [Text Block] rr_RiskTextBlock Biotechnology Companies Risk. Biotech companies invest heavily in research and development which may not necessarily lead to commercially successful products. These companies are also subject to increased governmental regulation which may delay or inhibit the release of new products. Many biotech companies are dependent upon their ability to use and enforce intellectual property rights and patents. Any impairment of such rights may have adverse financial consequences. Biotech stocks, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Biotech companies can be significantly affected by technological change and obsolescence, product liability lawsuits and consequential high insurance costs.

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.

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.

The extent of such technologies’ versatility has not yet been fully explored. Consequently, the Fund’s holdings may include equity securities of operating companies that have exposure to a wide variety of industries, and the economic fortunes of certain companies held by the Fund may be significantly tied to such industries. Currently, there are few public companies for which these emerging technologies represent an attributable and significant revenue or profit stream, and such technologies may not ultimately have a material effect on the economic returns of companies in which the Fund invests.

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.
◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.
◦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 the 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.

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 the FTSE Russell Group (the “Index Provider”).
FTSE PE/VC Index
For both of the FTSE PE (Buyout) and VC indices, there is both a benchmark index (each, a “Benchmark Index”) and a tracking or investable Index.
The FTSE PE Buyout Benchmark Index includes nearly 5,400 private equity- backed companies with a total value of nearly $5 trillion. The FTSE VC Benchmark Index includes over 13,000 venture capital backed companies valued at over $2.5 trillion. Both Benchmark Indices have specific investable indices that seek to track the performance of the FTSE Benchmark Indices through portfolios of liquid assets using proprietary econometric models. These “tracking” indices, the FTSE Private Equity Buyout Index and the FTSE Venture Capital Index, are both available on Bloomberg with daily pricing (tickers: TRPEI and TRVCI).
The Index is a rules-based index that aims to provide exposure to a portfolio that mimics the returns of a theoretical investment in a diversified pool of private equity and venture capital-backed companies. The Index is comprised of varying weights to the FTSE Private Equity Buyout Index (the “Buyout Index”) and the FTSE Venture Capital Index (the “VC Index”). The Buyout Index weight will be set at a range of 50% to 95%, with the balance allocated to the VC Index. The Index’s relative weights to the Buyout Index and VC Index are determined at each calendar month-end based on optimal relative weighting over recent time periods. The Index is calculated and published daily.
The Buyout Index seeks to replicate the return profile of the private equity buyout asset class by constructing a combination of sector portfolio returns that are designed to track the performance of private equity sector investments by holding liquid exchange traded instruments, including publicly traded equities, ETFs and futures contracts on equity indexes, rather than investing directly in private equity-backed firms. The FTSE PE Buyout Index seeks to track the medium-term performance of the FTSE PE Buyout Benchmark Index. The FTSE Venture Capital Index seeks to replicate the return profile of the venture capital industry by constructing a theoretical dynamic portfolio in public, liquid assets, including publicly traded equities, ETFs and futures contracts on equity indexes, that tracks the movements of the FTSE VC Benchmark Index, which in turn tracks the venture capital industry. The FTSE PE Buyout Benchmark Index and FTSE VC Benchmark Index attempt to measure the aggregate gross performance of the U.S. private equity and venture capital industries, respectively, by tracking private equity and venture capital funding transactions, which are not available for public investment. FTSE gathers data on these transactions at select times, including during leveraged buyouts, buyouts, initial and follow-on venture rounds, and exit events.For months in which there is not a new company valuation due to a funding round, the Benchmark Index has a valuation model that uses a combination of private market and public market variables to estimate the value of the company until the next round of funding or a transaction occurs. As new data is gathered each quarter by FTSE, the value of the applicable benchmark Index increases or decreases. The “tracking” Indices are accordingly updated each month as they seek to track the performance of the Benchmark Indices as closely as possible. The Buyout Benchmark Index and VC Benchmark Index are each calculated and published by FTSE quarterly.
The Buyout Index and VC Index are each comprised of six sector portfolios. Each sector portfolio represents a specific business subsector within the private equity or venture capital markets (e.g., consumer, technology, etc.). Each sector portfolio includes a set of equity securities, exchange-traded funds (“ETFs”) and futures contracts that are intended to replicate the returns of the corresponding sector within the Buyout Index or VC Index, respectively. The sectors are then weighted to mirror the distribution of investments across the private equity or venture capital markets, as applicable.
The sectors included in the Buyout Index are:
•Consumer Noncyclical
•Consumer Cyclical
•Energy, Utilities and Industrials
•Health Care
•Technology
•Financials
The sectors included in the VC Index are:
•Materials, Industrials, Energy and Utility
•Consumer Services
•Health Care
•Technology Equipment
•Software and Tech Services
•Telecommunications
Securities are selected for the Buyout Index and VC Index sector portfolios using a systematic process that begins with the universe of securities included in the corresponding FTSE publicly traded sector indices. From each FTSE publicly traded sector index securities are selected in order based upon market capitalization size until a desired beta and correlation to the sector index is achieved. Security weights within each sector portfolio correspond to their relative market capitalization, subject to a maximum weight of 4.5% for any name, within the portfolio.
Once the sector portfolios of the Buyout Index or VC Index have been established, proprietary models are run that provide the additional outputs that are incorporated into the portfolios. These models use statistical and/or econometric techniques and information from the macroeconomic environment, financial markets, and the universe of private equity and venture capital-backed firms to construct portfolios that seek to match the risk/return exposures of the private firms that make up the FTSE PE Buyout Benchmark Index or FTSE VC Benchmark Index, as appropriate. The outputs of these models include potential leverage adjustment (levels ranging from 0x to 2x) and inter-sector weighting adjustments. The adjustments within a sector portfolio seek to more precisely mimic sector risk exposures reflected in the FTSE PE Buyout Benchmark Index or FTSE VC Benchmark Index by increasing or decreasing the relative weights to the sectors. The leverage adjustments do not change the selected total leverage to the portfolio but they may increase or decrease the effective risk exposures of the individual sector portfolio. Leverage and weights are computed after the market close of the final trading day in a calendar month and applied at the market close on the first day of trading of the new month. Sector weights and leverage may change over the course of each month due to performance, and the models do not require trading away from the naturally arising weights and leverage until the rebalance at the end of the month.
The Index was established in 2024 and is owned and maintained by the Index Provider.
The Fund’s Investment Strategy
Under normal circumstances, the Fund will seek to invest at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) in a combination of publicly traded equities, ETFs and futures contracts that provide exposure to the private equity and venture capital markets (i.e., 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.
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. The Index, and consequently the Fund, is expected to have significant exposure to companies in the Technology Sector. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single issuer or small number of issuers than diversified funds.

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 PE/VC 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 PE/VC 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 PE/VC ETF | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk. Derivatives include instruments and contracts that are based on, and are valued in relation to, one or more underlying securities, financial benchmarks or indices, such as futures contracts. Derivatives typically have economic leverage inherent in their terms. Futures contracts can be highly volatile, illiquid, and difficult to value. Adverse changes in the value or level of the underlying asset or index, which the Fund may not directly own, can result
in a loss to the Fund substantially greater than the amount invested in the derivative itself. The use of derivative instruments also exposes the Fund to additional risks and transaction costs. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. A small position in futures contracts could have a potentially large impact on the Fund’s performance. Trading restrictions or limitations may be imposed by an exchange, and government regulations may restrict trading in futures contracts.
Pacer PE/VC 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.
◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.
◦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.

Pacer PE/VC ETF | Futures Contract Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Futures Contract Risk. The primary risks associated with the use of futures contracts, which may adversely affect the Fund’s NAV and total return, are (a) the imperfect correlation between the change in market value of the underlying securities or index and the price of the futures contract; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) the possibility that the counterparty will default in the performance of its obligations; and (d) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it maybe disadvantageous to do so.
Pacer PE/VC ETF | Large-Capitalization Investing Risk Member  
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 PE/VC ETF | Management Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Management Risk. To the extent the Fund uses a representative sampling strategy to obtain exposure to the Index, the Fund’s ability to track the performance of the Index will be contingent on the ability of the Fund’s sub-adviser to identify a subset of Index components whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Index as a whole.
Pacer PE/VC ETF | New Fund Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock New Fund Risk. The Fund is new with no operating history. As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it may experience greater tracking error to its Index than it otherwise would at higher asset levels, or it could ultimately liquidate. The Fund’s distributor does not maintain a secondary market in Fund shares.
Pacer PE/VC ETF | Other Investment Companies Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Other Investment Companies Risk. The Fund will incur higher and duplicative expenses when it invests in other investment companies such as ETFs. 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.
Pacer PE/VC 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 PE/VC 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. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.
Pacer PE/VC 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.
▪Information Technology Sector Risk. The Fund may invest in companies in the information technology sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. 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.
