Environmental:
Temperature range:
Operating temperature range -70ºC to + 125 ºC.
Wire sealing: A resilient socket grommet is permanently bonded to the wire entry face of the socket
so as to provide moisture sealing capabilities, contact M39029/101-553 wire sealing range diameter
.040 min to .083 max, (1.02 to 2.11 mm), for AWG size 20 wire (for coil contacts) and AWG size 20
wire (for load contacts).
Contacts: Contacts shall be in accordance with table I. Contacts shall be crimp removable type rear
release and accept relay pins size 20 (.039 through .041 inch diameter (0.99 through 1.04 mm)).
Insertion and withdrawal force: The insertion and withdrawal forces shall be as specified in table II.

Durability: Shall be in accordance with MIL-PRF-12883.
Vibration (sinusoidal): In accordance with MIL-STD-202, method 204, test condition G.
a. Except that the frequency range shall be varied logarithmically between the limits of 10 and
3,000 Hz.
b. Except that the procedure of method of 201 of MIL-STD-202, or an equivalent industry
standard, may be applied during 10-55 Hz band of the vibration frequency range.
Vibration (random): In accordance with MIL-STD-1344, method 2005, test condition V, letter G, with a
duration of 15 minutes. The mating relay shall be used as the test gage.
Shock (mechanical): In accordance with MIL-STD-202, method 213, condition C, except peak value
shall be 200 g's.
Torque: Relay sockets and hardware shall be subjected to testing torque as specified in table III.
Sockets shall be installed in mounting panel when test torque is applied. No physical damage will be
permitted. Torque shall be maintained for a reasonable period of time to insure stud, socket, and
associated hardware have not been damaged.
