Item 1.Security and Issuer The class of equity security to which this statement on Form Schedule 13D relates is the Common Stock, par value $0.01 per share ("Securities"), of IDEX Corporation (the "Issuer), a Delaware corporation, with principal offices located at 630 Dundee Road, Suite 400, Northbrook, Illinois, 60062. This Amendment No. 29 to Schedule 13D on IDEX Corporation (the "Issuer") is being filed on behalf of the undersigned to amend the Schedule 13D, as amended (the "Schedule 13D") which was originally filed on June 16, 1989. Item 2. Identity and Background This statement is being filed by Mario J. Gabelli ("Mr. Gabelli") and various entities which he directly or indirectly controls or for which he acts as chief investment officer. These entities, except for Lynch Corporation ("Lynch"), Spinnaker Industries, Incorporated ("Spinnaker"), Western New Mexico Telephone Company ("Western New Mexico"), Entoleter, Inc. ("Entoleter"), Lynch Telecommunications Corporation ("Lynch Telecom"), Lynch Telephone Corporation ("Lynch Telephone") and Inter-Community Telephone Company ("Inter-Community") (collectively, "Lynch and its affiliates"), engage in various aspects of the securities business, primarily as investment adviser to various institutional and individual clients, includ- ing registered investment companies and pension plans, as broker/dealer and as general partner of various private invest- ment partnerships. Certain of these entities may also make investments for their own accounts. The foregoing persons in the aggregate often own beneficially more than 5% of a class of equity securities of a particular issuer. Although several of the foregoing persons are treated as institutional investors for purposes of reporting their beneficial ownership on the short-form Schedule 13G, the holdings of those who do not qualify as institutional investors may exceed the 1% threshold presented for filing on Schedule 13D or implementation of their investment philosophy may from time to time require action which could be viewed as not completely passive. In order to avoid any question as to whether their beneficial ownership is being reported on the proper form and in order to provide greater investment flexibility and administra- tive uniformity, these persons have decided to file their benefi- cial ownership reports on the more detailed Schedule 13D form rather than on the short-form Schedule 13G and thereby to provide more expansive disclosure than may be necessary. (a), (b) and (c) - This statement is being filed by one or more of the following persons: Gabelli Funds, Inc. ("GFI"), GAMCO Investors, Inc. ("GAMCO"), Gabelli Securities, Inc. ("GSI"), Gabelli & Company, Inc. ("Gabelli & Company"), Gabelli Performance Partnership L.P. ("GPP"), GLI, Inc.

(d) and (e) - On December 8, 1994, the SEC instituted and simultaneously accepted offers for the settlement of an administrative proceeding against Gabelli & Company and GAMCO. The order instituting the proceeding included a finding, which Gabelli & Company and GAMCO neither admitted nor denied, that they failed to implement and maintain policies and procedures reasonably designed to prevent the misuse of material, nonpublic information by not sepecifically addressing the special circumstances that arose from their affiliation with Lynch Corporation, a public company. To resolve this matter, Gabelli & Company and GAMCO agreed to cease and desist from violating Section 15(f) of the 1934 Act and Section 204A of the Advisers Act, respectively. They further agreed to each pay a civil penalty in the amount of $50,000, and to retain, and adopt the recommendations of, an independant consultant regarding their Section 15(f) and Section 204A policies and procedures. On December 13, 1991, the Virginia State Corporation Commission entered an order of settlement in final disposition of matters arising from an allegation that GAMCO had transacted business in Virginia as an investment adviser without having been registered as such under Virginia Code Section 13.1-504A or an exemption therefrom. GAMCO consented to the entry of the order without admitting or denying the allegation and without a hearing. The terms of the order provide that GAMCO would pay a fine and costs totalling fifty-five thousand dollars and would not transact business in Virginia as an investment adviser unless it was registered as such under section 13.1-504A or was exempt from registration. (f) - Reference is made to Schedule I hereto. Item 3. Source and Amount of Funds or Other Consideration All Reporting Persons used an aggregate of approximately $22,799,858 to purchase Securitites beneficially owned by them as reported in Item 5 below. GAMCO and GFI used approximately $14,975,448 and $8,334,906, respectively, of funds that were provided throught the accounts of certain of their investment advisory clients (and, in the case of some such accounts at GAMCO, may be through the borrowings from margin accounts) in order to purchase the Securities for such clients. GIASL used approximately $37,050 of funds from a client account to purchase the Securities reported by it. Item 4. Purpose of Transaction Each of the Reporting Persons, with the exceptions of Lynch and its affiliates, has purchased and holds the Securities reported by it for investment for one or more accounts over which it has shared, sole, or both investment and/or voting power, for its own account, or both. The Reporting Persons, with the exceptions of Lynch and its affiliates, are engaged in the business of securities analysis and investment and pursue an investment philosophy of identifying undervalued situations. In pursuing this investment philosophy, the Reporting Persons analyze the operations, capital structure and markets of companies in which they invest, including the Issuer, on a continuous basis through analysis of documentation and discussions with knowledgeable industry and market observers and with representatives of such companies (often at the invitation of management). The Reporting Persons do not believe they possess material inside information concerning the Issuer. As a result of these analytical activities one or more of the Reporting Persons may issue analysts reports, participate in interviews or hold discussions with third parties or with management in which the Reporting Person may suggest or take a position with respect to potential changes in the opera- tions, management or capital structure of such companies as a means of enhancing shareholder values. Such suggestions or positions may relate to one or more of the transactions specified in clauses (a) through (j) of Item 4 of the Schedule 13D form, including, without limitation, such matters as disposing of one or more businesses, selling the company or acquiring another company or business, changing operating or marketing strategies, adopting or not adopting, certain types of anti-takeover measures and restructuring the company's capitalization or dividend poli- cy. Each of the Reporting Persons intends to adhere to the foregoing investment philosophy with respect to the Issuer. How- ever, none of the Reporting Persons intends to seek control of the Issuer or participate in the management of the Issuer, and any Reporting Person that is registered as an investment company under the l940 Act will participate in such a transaction only following receipt of an exemption from the SEC under Rule l7D-l under the l940 Act, if required, and in accordance with other applicable law. In pursuing this investment philosophy, each Reporting Person will continuously assess the Issuer's business, financial condition, results of operations and prospects, general economic conditions, the securities markets in general and those for the Issuer's securities in particular, other developments and other investment opportunities, as well as the investment objectives and diversification requirements of its shareholders or clients and its fiduciary duties to such shareholders or clients. Depending on such assessments, one or more of the Reporting Persons may acquire additional Securities or may determine to sell or otherwise dispose of all or some of its holdings of Securities. Although the Reporting Persons share the same basic investment philosophy and although portfolio decisions are made by or under the supervision of Mr. Gabelli, the investment objectives and diversification requirements of various clients differ from those of other clients so that one or more Reporting Persons may be acquiring Securities while others are disposing of Securities. With respect to voting of the Securities, the Reporting Persons have adopted general voting policies relating to voting on specified issues affecting corporate governance and sharehold- er values. Under these policies, the Reporting Persons generally vote all securities over which they have voting power in favor of cumulative voting, financially reasonable golden parachutes, one share one vote, management cash incentives and pre-emptive rights and against greenmail, poison pills, supermajority voting, blank check preferred stock and super-dilutive stock options. Exceptions may be made when management otherwise demonstrates superior sensitivity to the needs of shareholders. In the event that the aggregate voting position of all joint filers shall exceed 25% of the total voting position of the issuer then the proxy voting committees of each of the Funds shall vote their Fund's shares independently. Each of the Covered Persons who is not a Reporting Person has purchased the Securities reported herein as benefi- cially owned by him for investment for his own account or that of one or more members of his immediate family. Each such person may acquire additional Securities or dispose of some or all of the Securities reported herein with respect to him. Other than as described above, none of the Reporting Persons and none of the Covered Persons who is not a Reporting Person has any present plans or proposals which relate to or would result in any transaction, change or event specified in clauses (a) through (j) of Item 4 of the Schedule 13D. Item 5. Interest In Securities Of The Issuer (a) The aggregate number and percentage of Securities to which this Schedule 13D relates is 2,165,640 shares, repre- senting 11.29% of the 19,181,604 shares outstanding as reported in the most recently filed Form 10-Q for the quarter ended March 31, 1996. The Reporting Persons beneficially own those Securities as follows: Shares of % of Common Class of Name Stock Common GAMCO As Principal 0 0.00% As Agent 1,361,690 7.42% GFI As Principal 0 0.00% As Agent 742,200 3.86% GIASL 1,000 0.01% Mr. Gabelli 0 0.00% Mr. Gabelli is deemed to have beneficial ownership of the Securities owned beneficially by each of the foregoing persons and GFI is deemed to have beneficial ownership of the securities owned beneficially by each of the foregoing persons other than Mr. Gabelli. (b) Each of the Reporting Persons and Covered Persons has the sole power to vote or direct the vote and sole power to dispose or to direct the disposition of the Securities reported for it, either for its own benefit or for the benefit of its investment clients or its partners, as the case may be, except that GAMCO Investors, Inc. does not have authority to vote 60,750 of the reported shares, and except that GFI has sole dispositive and voting power with respect to the 742,200 shares of the Issuer held by the the Funds, so long as the aggregate voting interest of all joint filers does not exceed 25% of their total voting interest in the Issuer and in that event, the Proxy Voting Committee of each of the Funds shall respectively vote that Fund's shares, and except that, at any time, the Proxy Voting Committee of each such Fund may take and exercise in its sole discretion the entire voting power with respect to the shares held by such Fund under special circumstances such as regulatory considerations, and except that the power of Mr. Gabelli and GFI is indirect with respect to Securities beneficially owned directly by other Reporting Persons. (c) Information with respect to all transactions in the Securities which were effected during the past sixty days by each of the Reporting Persons and Covered Persons is set forth on Schedule II annexed hereto and incorporated herein by reference. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer The powers of disposition and voting of GFI and GAMCO with respect to Securities owned beneficially by them on behalf of their investment advisory clients, of GLI, Mr. Gabelli and GSI with respect to Securities owned beneficially by them on behalf of the partnerships which they directly or indirectly manage, and of GIL and GAL with respect to Securities owned beneficially by it on behalf of its shareholders, are held pursuant to written agreements with such clients and partnerships.
