Unless otherwise specified, tolerance is .010 (0.25 mm). 4. Terminal numbers need not appear on relay headers
5、provided there is affixed positively identifies each terminal location specified herein. 5. The use of diodes on ac relays is optional. Actual application must be shown on label. 6. Pins to be perpendicular to header surface within one degree. 7. In the event of conflict between the text of this sta
6、ndard and the references cited herein, the text of this standard shall take precedence. 8. Referenced Government documents of the issue listed in that issue of the Department of Defense Index of Specifications and Standards (DODISS) specified in the solicitation forms a part of this standard to the
7、extent specified herein. 9. Socket pin terminals shall provide the operational, environmental, and interface characteristics to provide a reliable interconnect to gold-plated contacts. Terminals shall be gold plated. One system for gold plating that may be used is ASTM B488, type 3, class 1.25 with
8、a nickel underplate of 50 to 150 microinches thick. The gold plating system shall enable the product to meet the performance requirements of this specification and shall be approved by the qualifying activity. 10. Gasket shall provide a reliable seal between the relay and mating socket that will mee
9、t the environmental, operational, and interface requirements of the relay with the mating socket. The gasket shall have thickness .075, recess .047 in bracket .005. Gasket material according to AMS 3332 has been considered acceptable. 11. Gasket shall provide a reliable seal between the relay and ma
10、ting socket that will meet the environmental, operational, and interface requirements of the relay with the mating socket. The gasket shall have shore hardness 20 5, thickness .047 .008. Gasket material according to AMS 3332 has been considered acceptable. FIGURE 1. Dimensions and configurations - C
