MIL-DTL-12883/51B
Contacts: Contacts are not supplied with the socket module use the following contacts:
20 gage - M39029/57-357 for (.041) terminal pins.
16 gage - M39029/57-358 for (.062) terminal/ground pins.
Minimum holding force: 3 lbs (13.34 Newton) when assembled to track (MIL-DTL-12883/49).
Part or Identifying Number (PIN): The PIN shall consist of the basic number of this specification sheet
and the dash number from table I.

1/ Reference MIL-PRF-89536 for supersession data on MIL-PRF-6106 relays.
2/ To be used in conjunction with relay mounting track MIL-DTL-12883/49 and applicable relay.
3/ Each socket module delivered shall have a hole pattern that:
a. Permits installation of the mating relay into the socket module when the relative orientation
of the two is correct.
b. Prevents installation of this mating relay into the socket module when the relative
orientation of the two is not correct.
c. Prevents installation of all other relays into the socket module regardless of the orientation
of the socket module and the relay.
4/ Any hole molded into the socket module that results in a pattern that is not consistent with 3/ shall
be filled. The filling means shall exhibit the following characteristics:
a. If a nonmetal, the fill material shall be proved to comply with the reversion resistance and
hydrolytic stability requirements of MIL-HDBK-454, requirement 47.
b. Shall be restrained from motion relative to the module material into which it is inserted.
c. Shall have hardness comparable to that of the module material into which it is inserted.
