MIL-DTL-39030/3E
REQUIREMENTS:
Dimensions and configurations: See figures 1 thru 6.
Electrical characteristics: See table I.
Materials:
Body and connector: Corrosion-resistant steel in accordance with SAE-AMS-QQ-S-763 or
ASTM A484/A484M and ASTM A582/A852M.
Finish: See table I.
Contact pin and contact socket: Beryllium copper in accordance with ASTM B194, ASTM B196/B196M, or ASTM
B197/B197M.
Finish: The male pin shall be plated to a minimum gold thickness of 50 micro inches (1.27µm) in accordance
with ASTM B488, type ll, code C, class 1.27, over 50 micro inches (1.27 µm) minimum of nickel in accordance
with SAE-AMS-QQ-N-290, class 1, measured anywhere along the mating surface, for all series. The socket
contact shall be plated to a minimum of 50 micro inches (1.27µm) of gold in accordance with ASTM B488, type
ll, code C, class 1.27, over 50 micro inches (1.27 µm) minimum of nickel in accordance with SAE-AMS-QQ-N-
290, class 1, including the I.D., measured at a depth of .040 inch minimum.
The plating on non-significant surfaces in the I.D. shall be of sufficient thickness to ensure plating continuity
and uniform utility and protection. This plating may consist of an underplate only. A silver underplate shall not
be permitted.
Bead chain and lug: Corrosion-resistant steel or plastic.
Weight: See table I.
