Caution note to observe polarity must appear on relays with dc coils. 5/ Terminal numbers need not appear on relay headers provided there is affixed to the relay a suitable legible circuit diagram that permanently and positively identifies each terminal location specified hereon. 6/ The use of d

6、iodes on ac relays is optional. Actual application must be shown on label. 7/ Shock, vibration, and acceleration requirements application with coils de-energized. 8/ In the event of conflict between the text of this specification and the references cited herein, the text of this specification shall

7、take precedence. 9/ 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 specification to the extent specified herein. 10/ Socket pin terminals shall provide th

8、e 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 a nickel underplate of 50 to 150 microinches thick. The gold plat

9、ing system shall enable the product to meet the performance requirements of this specification and shall be approved by the qualifying activity. 11/ Gasket shall provide a reliable seal between the relay and mating socket that will meet the environmental, operational, and interface requirements of t

10、he relay with the mating socket. The gasket shall have thickness .075, recessed .047 in to bracket. Gasket material according to AMS 3332 has been considered acceptable. FIGURE 1.
