5、 Unless otherwise specified, tolerance is .010 (0.25 mm). 4. Terminal numbers need not appear on relay headers provided there is affixed to the relay a suitable legible circuit diagram that identifies each terminal location specified. 5. Socket pin terminals shall provide the operational, environmen
6、tal, 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 plating system shall enable t
7、he product to meet the performance requirements of this specification and shall be approved by the qualifying activity. 6. Gasket shall provide a reliable seal between the relay and mating socket that will meet the environmental, operational, and interface requirements of the relay with the mating s
8、ocket. The gasket shall have shore hardeness 20 5, thickness .050 .05. Gasket material according to AMS 3332 has been considered acceptable. FIGURE 1.
