Pacer US Export Leaders ETF \| Calculation Methodology Risk Member
Prospectus [Line Items]
Risk [Text Block]	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 US Export Leaders ETF \| Concentration Risk Member
Prospectus [Line Items]
Risk [Text Block]	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 US Export Leaders ETF \| Diversification Risk Member
Prospectus [Line Items]
Risk [Text Block]	Diversification Risk. The Fund is classified as “diversified” under the 1940 Act. However, the Fund may become “non‑diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index. Operating as “non-diversified” may make the Fund more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.
Pacer US Export Leaders ETF \| Equity Market Risk Member
Prospectus [Line Items]
Risk [Text Block]	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 US Export Leaders ETF \| ETF Risks Member
Prospectus [Line Items]
Risk [Text Block]	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 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 US Export Leaders ETF \| Foreign Sales Risk Member
Prospectus [Line Items]
Risk [Text Block]	Foreign Sales Risk. The Fund invests in companies that derive a significant portion of their sales to non-U.S. customers. Consequently, investments in such companies may be subject to risk of loss due to unfavorable changes in currency exchange rates, political, economic or social changes or instability in such non-U.S. countries, events affecting the transportation, shipping or delivery of goods to such customers, and changes in U.S. or foreign laws or regulations affecting exports.
Pacer US Export Leaders ETF \| Large-Capitalization Investing Risk Member
Prospectus [Line Items]
Risk [Text Block]	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 US Export Leaders ETF \| Mid-Capitalization Investing Member
Prospectus [Line Items]
Risk [Text Block]	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 US Export Leaders ETF \| Passive Investment Risk Member
Prospectus [Line Items]
Risk [Text Block]	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 US Export Leaders ETF \| Sector Risk Member
Prospectus [Line Items]
Risk [Text Block]	▪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. 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.

Pacer US Export Leaders ETF \| Tracking Risk Member
Prospectus [Line Items]
Risk [Text Block]	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.

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.

Risk [Text Block]	▪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. •Communication 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.

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. Additionally, the Fund’s return may not track the return of the Index if the Fund is not able to replicate the holdings of the Index due to the diversification requirements described above under “Tax Risk,” which apply to the Fund but not the Index.
Pacer Data & Infrastructure Real Estate ETF \| Concentration In Real Estate Risk Member
Prospectus [Line Items]
Risk [Text Block]	Concentration in Real Estate Risk. The Index, and consequently the Fund, is expected to concentrate its investments (i.e., hold more than 25% of its total assets) in real estate companies. As a result, 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, the real estate industry may be out of favor and underperform other industries or groups of industries.
Pacer Data & Infrastructure Real Estate ETF \| Currency Exchange Rate Risk Member
Prospectus [Line Items]
Risk [Text Block]	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 Data & Infrastructure Real Estate ETF \| Emerging Markets Risk Member
Prospectus [Line Items]
Risk [Text Block]	Emerging Markets Risk. The Fund may invest in companies organized in emerging market nations. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value.
Pacer Data & Infrastructure Real Estate ETF \| Foreign Securities Risk Member
Prospectus [Line Items]
Risk [Text Block]	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 Data & Infrastructure Real Estate ETF \| Geographic Concentration Risk 1 Member
Prospectus [Line Items]
Risk [Text Block]	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.
Pacer Data & Infrastructure Real Estate ETF \| International Operations Risk Member
Prospectus [Line Items]
Risk [Text Block]	International Operations Risk. Investments in companies with significant business operations outside of the United States may involve certain risks that may not be present with investments in U.S. companies. For example, international operations may be subject to risk of loss due to foreign currency fluctuations; changes in foreign political and economic environments, regionally, nationally, and locally; challenges of complying with a wide variety of foreign laws, including corporate governance, operations, taxes, and litigation; differing lending practices; differences in cultures; changes in applicable laws and regulations in the United States that affect international operations; changes in applicable laws and regulations in foreign jurisdictions; difficulties in managing international operations; and obstacles to the repatriation of earnings and cash. These and other factors can make an investment in the Fund more volatile than other types of investments.
Pacer Data & Infrastructure Real Estate ETF \| Natural Language Processing (NLP) Model Risk Member
Prospectus [Line Items]
Risk [Text Block]	Natural Language Processing (NLP) Model Risk. Solactive uses NLP models to assist in the development of the Solactive Small Modular Reactor Index, which in turn is used in selecting components of the Index. Solactive’s description of the investment theme is used by the NLP screening models to identify relevant companies for index consideration. The investment theme must be accurately described in order for the NLP models to identify companies that reflect the themes of the Solactive Small Modular Reactor Index. If the description of the theme is incorrect or incomplete, the NLP model may identify companies that are not relevant to the Fund’s investment theme or fail to identify companies that are relevant. As a result, securities may be included in or excluded from the Solactive Small Modular Reactor Index that would have been excluded or included had the description of the theme been correct and complete. If the composition of the Solactive Small Modular Reactor Index reflects such errors, the Fund’s portfolio can be expected to also reflect the errors. There is no guarantee that the Solactive Small Modular Reactor Index will reflect the theme exposures intended. Solactive relies on the integrity of the data being analyzed and its review processes could be adversely affected if erroneous or outdated data is utilized.
Pacer Data & Infrastructure Real Estate ETF \| Nuclear Power Companies Risk Member
Prospectus [Line Items]
Risk [Text Block]	Nuclear Power Companies Risk. Nuclear power companies may face considerable risk as a result of incidents and accidents, breaches of security, ill-intentioned acts of terrorism, natural disasters, equipment malfunctions or mishandling in storage, handling, transportation, treatment or conditioning of substances and nuclear materials. Such events could have serious consequences, especially in the case of radioactive contamination and irradiation of the environment, for the general population, as well as a material, negative impact on nuclear infrastructure companies. In addition, nuclear infrastructure companies are subject to competitive risk associated with the prices of other energy sources, such as natural gas and oil. Consumers of nuclear energy may have the ability to switch between nuclear energy and other energy sources and, as a result, during periods when competing energy sources are less expensive, the revenues of nuclear infrastructure companies may decline with a corresponding impact on earnings. Nuclear activity is also subject to particularly detailed and restrictive regulations, with a scheme for the monitoring and periodic re-examination of operating authorization, which primarily takes into account nuclear safety, environmental and public health protection, and also national security considerations, including terrorist threats in particular. These regulations and any future regulations may be subject to significant tightening by national and international authorities. This could result in increased operating costs, which would have a negative impact on nuclear power companies and may cause operating businesses related to nuclear energy to become unprofitable or impractical to operate.
Pacer Data & Infrastructure Real Estate ETF \| Real Estate Companies Risk Member
Prospectus [Line Items]
Risk [Text Block]	Real Estate Companies Risk. The Fund invests in real estate companies, including REITs and real estate holdings companies, which will expose investors to the risks of owning real estate directly, as well as to the risks that relate specifically to the way in which such companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments. The U.S. real estate market may, in the future, experience and has, in the past, experienced a decline in value, with certain regions experiencing significant losses in property values. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s volatility and losses. Exposure to such real estate may adversely affect Fund performance. In addition to the foregoing risks common to most real estate companies, companies in certain real estate sectors may have additional unique risks. ◦Risks of Investing in the Data & Infrastructure Real Estate Sector. Companies in the Data & Infrastructure Real Estate sector may be affected by unique supply and demand factors that do not apply to other real estate sectors, such as changes in demand for communications infrastructure, consolidation of tower sites, new technologies that may affect demand for communications towers, and changes in demand for wireless infrastructure and wireless connectivity.

Companies in the Data & Infrastructure Real Estate sector may be affected by unique supply and demand factors that do not apply to other real estate sectors, such as changes in demand for communications infrastructure, consolidation of tower sites, new technologies that may affect demand for communications towers, and changes in demand for wireless infrastructure and wireless connectivity.
Pacer Data & Infrastructure Real Estate ETF \| REIT Investment Risk Member
Prospectus [Line Items]
Risk [Text Block]	▪REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. In addition, to the extent the Fund holds interests in REITs, it is expected that investors in the Fund will bear two layers of asset-based management fees and expenses (directly at the Fund level and indirectly at the REIT level). The risks of investing in REITs include certain risks associated with the direct ownership of real estate and the real estate industry in general. These include risks related to general, regional and local economic conditions; fluctuations in interest rates and property tax rates; shifts in zoning laws, environmental regulations and other governmental action such as the exercise of eminent domain; cash flow dependency; increased operating expenses; lack of availability of mortgage funds; losses due to natural disasters; overbuilding; losses due to casualty or condemnation; changes in property values and rental rates; and other factors. In addition to these risks, REITs are dependent upon management skills and generally may not be diversified. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, REITs could possibly fail to qualify for the beneficial tax treatment available to REITs under the Internal Revenue Code of 1986, or to maintain their exemptions from registration under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund expects that dividends received from a REIT and distributed to Fund shareholders generally will be taxable to the shareholder as ordinary income, but may be taxable as return of capital. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting investments.

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.
Pacer Data & Infrastructure Real Estate ETF \| Small-Capitalization Investing Risk Member
Prospectus [Line Items]
Risk [Text Block]	Small-Capitalization Investing Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller capitalization companies than for larger, more established companies.
Pacer Data & Infrastructure Real Estate ETF \| Tax Risk Member

Risk [Text Block]	Tax Risk. To qualify for the favorable tax treatment generally available to regulated investment companies, the Fund must satisfy certain diversification requirements. In particular, the Fund generally may not acquire a security if, as a result of the acquisition, more than 50% of the value of the Fund’s assets would be invested in (a) issuers in which the Fund has, in each case, invested more than 5% of the Fund’s assets or (b) issuers more than 10% of whose outstanding voting securities are owned by the Fund. While the weighting of the Index is not inconsistent with these rules, given the concentration of the Index in a relatively small number of securities, it may not always be possible for the Fund to fully implement a replication strategy or a representative sampling strategy while satisfying these diversification requirements. The Fund’s efforts to satisfy the diversification requirements may affect the Fund’s execution of its investment strategy and may cause the Fund’s return to deviate from that of the Index, and the Fund’s efforts to replicate or represent the Index may cause it inadvertently to fail to satisfy the diversification requirements. If the Fund were to fail to satisfy the diversification requirements, it could incur penalty taxes and be forced to dispose of certain assets, or it could fail to qualify as a regulated investment company. If the Fund were to fail to qualify as a regulated investment company, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income.

Risk [Text Block]	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.

Investment Risks

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.

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]

Diversification Risk. The Fund is classified as “diversified” under the 1940 Act. However, the Fund may become “non‑diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index. Operating as “non-diversified” may make the Fund more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.

Risk [Text Block]

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 US Export Leaders ETF | ETF Risks Member

Prospectus [Line Items]

Risk [Text Block]

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 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.

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.

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.

Natural Language Processing (NLP) Model Risk. Solactive uses NLP models to assist in the development of the Solactive Small Modular Reactor Index, which in turn is used in selecting components of the Index. Solactive’s description of the investment theme is used by the NLP screening models to identify relevant companies for index consideration. The investment theme must be accurately described in order for the NLP models to identify companies that reflect the themes of the Solactive Small Modular Reactor Index. If the description of the theme is incorrect or incomplete, the NLP model may identify companies that are not relevant to the Fund’s investment theme or fail to identify companies that are relevant. As a result, securities may be included in or excluded from the Solactive Small Modular Reactor Index that would have been excluded or included had the description of the theme been correct and complete. If the composition of the Solactive Small Modular Reactor Index reflects such errors, the Fund’s portfolio can be expected to also reflect the errors. There is no guarantee that the Solactive Small Modular Reactor Index will reflect the theme exposures intended. Solactive relies on the integrity of the data being analyzed and its review processes could be adversely affected if erroneous or outdated data is utilized.

Nuclear Power Companies Risk. Nuclear power companies may face considerable risk as a result of incidents and accidents, breaches of security, ill-intentioned acts of terrorism, natural disasters, equipment malfunctions or mishandling in storage, handling, transportation, treatment or conditioning of substances and nuclear materials. Such events could have serious consequences, especially in the case of radioactive contamination and irradiation of the environment, for the general population, as well as a material, negative impact on nuclear infrastructure companies. In addition, nuclear infrastructure companies are subject to competitive risk associated with the prices of other energy sources, such as natural gas and oil. Consumers of nuclear energy may have the ability to switch between nuclear energy and other energy sources and, as a result, during periods when competing energy sources are less expensive, the revenues of nuclear infrastructure companies may decline with a corresponding impact on earnings. Nuclear activity is also subject to particularly detailed and restrictive regulations, with a scheme for the monitoring and periodic re-examination of operating authorization, which primarily takes into account nuclear safety, environmental and public health protection, and also national security considerations, including terrorist threats in particular. These regulations and any future regulations may be subject to significant tightening by national and international authorities. This could

result in increased operating costs, which would have a negative impact on nuclear power companies and may cause operating businesses related to nuclear energy to become unprofitable or impractical to operate.

Real Estate Companies Risk. The Fund invests in real estate companies, including REITs and real estate holdings companies, which will expose investors to the risks of owning real estate directly, as well as to the risks that relate specifically to the way in which such companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments. The U.S. real estate market may, in the future, experience and has, in the past, experienced a decline in value, with certain regions experiencing significant losses in property values. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s volatility and losses. Exposure to such real estate may adversely affect Fund performance.

In addition to the foregoing risks common to most real estate companies, companies in certain real estate sectors may have additional unique risks.

◦Risks of Investing in the Data & Infrastructure Real Estate Sector. Companies in the Data & Infrastructure Real Estate sector may be affected by unique supply and demand factors that do not apply to other real estate sectors, such as changes in demand for communications infrastructure, consolidation of tower sites, new technologies that may affect demand for communications towers, and changes in demand for wireless infrastructure and wireless connectivity.

▪REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. In addition, to the extent the Fund holds interests in REITs, it is expected that investors in the Fund will bear two layers of asset-based management fees and expenses (directly at the Fund level and indirectly at the REIT level). The risks of investing in REITs include certain risks associated with the direct ownership of real estate and the real estate industry in general. These include risks related to general, regional and local economic conditions; fluctuations in interest rates and property tax rates; shifts in zoning laws, environmental regulations and other governmental action such as the exercise of eminent domain; cash flow dependency; increased operating expenses; lack of availability of mortgage funds; losses due to natural disasters; overbuilding; losses due to casualty or condemnation; changes in property values and rental rates; and other factors.

In addition to these risks, REITs are dependent upon management skills and generally may not be diversified. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, REITs could possibly fail to qualify for the beneficial tax treatment available to REITs under the Internal Revenue Code of 1986, or to maintain their exemptions from registration under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund expects that dividends received from a REIT and distributed to Fund shareholders generally will be taxable to the shareholder as ordinary income, but may be taxable as return of capital. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting investments.

Small-Capitalization Investing Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller capitalization companies than for larger, more established companies.

Pacer Data & Infrastructure Real Estate ETF | Tax Risk Member

Prospectus [Line Items]

Risk [Text Block]

Tax Risk. To qualify for the favorable tax treatment generally available to regulated investment companies, the Fund must satisfy certain diversification requirements. In particular, the Fund generally may not acquire a security if, as a result of the acquisition, more than 50% of the value of the Fund’s assets would be invested in (a) issuers in which the Fund has, in each case, invested more than 5% of the Fund’s assets or (b) issuers more than 10% of whose outstanding voting securities are owned by the Fund. While the weighting of the Index is not inconsistent with these rules, given the concentration of the Index in a relatively small number of securities, it may not always be possible for the Fund to fully implement a replication strategy or a representative sampling strategy while satisfying these diversification requirements. The Fund’s efforts to satisfy the diversification requirements may affect the Fund’s execution of its investment strategy and may cause the Fund’s return to deviate from that of the Index, and the Fund’s efforts to replicate or represent the Index may cause it inadvertently to fail to satisfy the diversification requirements. If the Fund were to fail to satisfy the diversification requirements, it could incur penalty taxes and be forced to dispose of certain assets, or it could fail to qualify as a regulated investment company. If the Fund were to fail to qualify as a regulated investment company, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income.

Risk [Text Block]

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.
