Unless otherwise specified, tolerance is .010 (0.25 mm). 4. Terminal numbers shall not appear on relay headers.
5、There shall be affixed to the relay a legible circuit diagram that permanently and positively identifies each term in allocation specified herein. 5. The use of diodes on ac relays is optional. Actual application shall be shown on label. 6. Pins shall be perpendicular to header surface within one de
6、gree. 7. In the event of conflict between the text of this standard 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 Specification and Standards (DoDISS) specif
7、ied in the solicitation forms a part of this standard to the 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 pl
8、ating that may be used is ASTM B488, type 3, class 1.25 with 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 re
9、liable seal between the relay and mating 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 .075 .005 recessed .047 into bracket. Gasket material according to AMS 3332 has been con
10、sidered acceptable. FIGURE 1. Design, dimensions, and circuit diagram - Continued.
