3、o reproduction or networking permitted without license from IHS-,-,-MS25455H 2 NOTES: 1/ Dimensions are in inches. 2/ Metric equivalents are given for general information only. 3/ Unless otherwise specified, tolerance is .010 (0.25 mm). 4/ Terminal numbers need not appear on relay header provided th

4、ere is affixed to the relay a suitable legible circuit diagram that permanently and positively identifies each terminal location specified hereon. 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 1 degree.

5、7/ Relay is magnetically latched in both positions. Caution note to observe polarity must appear on relays with dc coils. 8/ Shock, vibration, and acceleration requirements applicable with coils de-energized. 9/ In the event of conflict between the text of this specification and the references cited

6、 herein, the text of this specification shall take precedence. 10/ 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 he

7、rein. 11/ 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 a nickel underplat

8、e 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. 12/ Gasket shall provide a reliable seal between the relay and mating socket that will meet the environmenta

9、l, operational, and interface requirements of the 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. Dimensions and configurations - Continued. Inches mm Inches mm .001 0.03
