1、EIA SPECIFICATIONSpecification for M12 Power Circular Connectors EIA-972 March 2018Electronic Components Industry Association EIA-972ANSI/EIA-972-2018 Approved: March 8, 2018 NOTICE EIA Engineering Specifications and Publications are designed to serve the public interest through eliminating misunder
2、standings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Specifications and Publications shall not in any respec
3、t preclude any member or nonmember of ECIA from manufacturing or selling products not conforming to such Specifications and Publications, nor shall the existence of such Specifications and Publications preclude their voluntary use by those other than ECIA members, whether the standard is to be used
4、either domestically or internationally. Specifications and Publications are adopted by ECIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, ECIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties
5、 adopting the Specification or Publication. This EIA specification is considered to have International Standardization implications, but the International Electrotechnical Commission activity has not progressed to the point where a valid comparison between the EIA standard and the IEC document can b
6、e made. This Specification does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Specification to establish appropriate safety and health practices and to determine the applicability of regulato
7、ry limitations before its use. NOTE The users attention is called to the possibility that compliance with this standard may require use of an invention covered by patent rights. By publication of this standard, no position is taken with respect to the validity of any such claim(s) or of any patent r
8、ights in connection therewith. If a patent holder has filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license, then details may be obtained from the standards developer Neither the
9、 standards developer nor ANSI is responsible for identifying patents for which a license may be required by an American National Standard or for conducting inquiries into the legal validity or scope of those patents that are brought to their attention.

12、plied along 3 mutually perpendicular planes, total 18 shocks; see figures 23 and 24. There shall be no discontinuities of 1 microsecond duration or longer. 5 Test schedule 5.1 General This test schedule shows the tests and the order in which they shall be carried out as well as the requirements to b
13、e met. Unless otherwise specified, mated sets of connectors shall be tested. When the initial tests have been completed, all specimens are divided up according to the test groups. Care shall be taken to keep a particular combination of connectors together during the complete test sequence, i.e., whe
14、n unmating is necessary for a certain test, the same connectors as before shall be mated for the subsequent tests. Before testing commences, the connectors shall have been stored for at least 24 hours in the non-inserted state under normal climatic conditions for testing. In the following test sequence tables, where an EIA test is specified without a letter suffix, the latest approved version of that test shall be used.
