Pin or socket contacts are removable and carry a gold plating finish.
Contact diameter : (1 mm) .039 dia. (U.S.A. size 20) ; dimensions conform to L 54-125 (MS 3190).
Contacts may be either crimped (specification : M 22520/2-01 and M 22520/2-02) or soldered on to the wire ends.
Meeting the requirements of MIL C 26482 A (Tests NF-C 20-700) (International Specification CEI 68-1).
Contacts resistance between pin and socket : less than 0.0020 ohm.
Maximum current rating : function of the number of contacts carrying this current and the permitted temperature increase.
When N contacts permanently carry a current of I amperes, the temperature increase of the connector is approximately :
(1°C)1.8°F x N where I = 4 amperes
(3° C) 5.4° F x N where I = 7 amperes
