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 shall not appear on relay headers.  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 degree.

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) specified 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 plating that may be used is ASTM 8488, 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 reliable 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 considered acceptable.
