REQUIREMENTS: Material:

Washer: Brass alloy C24000, C26000 or C26800, temper H02, in accordance with ASTM B 36/B 36M. Shell: Rubber in accordance with ASTM D2000, M3BC610A14C12E034F19.

Mating connectors:

Size 1 mates with connector MS 27143.

Size 2 mates with connector MS 27144, style 1, size 1. Size 3 mates with connector MS 27144, style 1, size 2.

Electrical requirements:

Voltage rating: 30 volts DC.

Current rating:	AWG size	Current (AMPS)
	16	13
	14	17
	12	23

Voltage drop: When connections are coupled, the voltage drop shall not exceed 20 millivolts and shall meet the requirements outlined in MIL-STD-202, method 307.

Dielectric strength: When connectors are coupled, the assembly shall meet the requirements of the dielectric strength test (1000 volts) outlined in MIL-STD-202, method 302.

Corrosion test: When connectors are coupled, the assembly shall meet the salt spray corrosion test outlined in MIL-STD-202, method 101 (5% saline solution, 200 hours duration).

Waterproof requirements: When connectors are coupled, the assembly shall be waterproof. Refer to

MIL-HDBK-1184, or equivalent, for guidance on waterproof testing.

Pull test: The terminal crimped to the cable shall withstand a pull test of 90 pounds (40 kilograms) on size 1, 60 pounds (27 kilograms) on size 2, and 40 pounds (18 kilograms) on size 3.

Separation force: The force required to uncouple the connectors shall not exceed 50 percent of the values expressed in the pull test above at -55°C and at 85°C.
