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. There shall be affixed to the relay a suitable legible circuit diagram that identifies each terminal location
specified.
5. Permanent magnet drive consists of a permanent magnet with its flux path switched and combined with the
electro-magnet flux.
6. Applicable to horizontal flange mount only. The circuit diagram, manufacturer's PIN, and the military PIN shall
be marked on the near side. The remaining portion of the nameplate data shall be marked on the far side.
7. Applicable to horizontal flange mount only. Relays shall be marked with the manufacturer's name or CAGE
code and date code. Marking shall be with the bottom of the print adjacent to the near side.
8. Socket pin terminals shall provide the operational, environmental, and interface characteristics to provide a
reliable interconnect to gold-plated contacts. Terminals, except the polarizing pin, 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 the product to meet the performance
requirements of this specification and shall be approved by the qualifying activity.
9. 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 15 to 35, thickness .050 ± .005. Gasket material according to SAE-AMS3332 has been considered
acceptable.
10. Track mount base, knob, latching pin, and post shall be corrosion resistant. One way of ensuring corrosion
resistance is to nickel plate stainless steel 303 with 100 microinches minimum thickness in accordance with
McDonnell Douglas P.S.13112 (Deutsch Relays, Inc., Patent number 3.790,915) or equivalent 100
microinches thick minimum.
11. Direction of hook openings does not affect function.
12. Indicated terminals shall be identified by a contrasting bead.
13. Plane of critical motion for vibration and shock is Y-axis.
