MIL-DTL-12883/54A
Wire sealing: A resilient grommet is permanently bonded to the wire entry face of the socket so as to
provide moisture sealing capabilities for AWG size 12, 16, and 20 wire as applicable (see figure 1,
front view).
Mechanical:
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 Hz
and 3,000 Hz.
b. Except that the procedure of method 201 of MIL-STD-202 may be applied during 10 Hz to 55
Hz band of the vibration frequency range.
c. Qualified mating relay used as a test gauge.
Vibration (random): In accordance with MIL-STD-1344, method 2005, test condition V, letter G, with
a test duration 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.
Mounting hardware: The mounting hardware shall allow mounting the socket above or below the
panel or chasses (see figure 2), and shall allow mounting and securing the relay to the socket without
disturbing the mounted socket or access to the wiring side of the socket. The hardware shall provide
the nominal spacing between socket surface and relay mounting flange, regardless of mounting
configuration.
Supplied with relay socket:
2 each per mounting stud:
.112-40 self locking nuts (.206 max dia x .176 max height).
.112 flat washers (.220 max O.D. x .018 max thick).
1 each per mounting stud:
.190-32 self locking nuts (.330 max dia x .190 max height).
.190 flat washers (.360 max O.D. x .019 max thick).
Fixed mounting studs: Studs shall be fixed into the mounting flange of the socket and shall be designed
so as to prevent rotation of the stud within the flange (see figure 2).
Insertion and withdrawal forces: The insertion and withdrawal forces of the relay and socket shall be as
specified in table II.
