MINIATURE Series



MAIN FEATURES

This series comprises plugs, receptacles and cable connecting plugs with pin or socket inserts.

CONTACTS

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 L54125 (MS 3190).
Special contacts for printed circuits - Consult our sales Engineering office.

CONTACT TERMINATION

Contacts may be either crimped (specification : M 22520/2.01 and M 22520/2.02) or soldered on to the wire ends.

ELECTRICAL DATA

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
Flashover voltage at (20° C) 68° F (mated connectors)4,19 or 37 contacts 3-7-12-27 or 55 contacts
At sea levelhigher than 2,000 V (r.m.s.) higher than 2,500V (r.m.s.)
at (56 mm) 2.20 in. of Hg (66,000 ft) higher than 400V (r.m.s.) higher than 500V (r.m.s.)
at(22mm) .867 in. of Hg (85,OOOft) higher than 350V (r.m.s.) higher than 450V (r.m.s.)
at (7.2mm) .284 in. of Hg (108,000 ft) higher than 300V (r.m.s.) higher than 400V (r.m.s.)

Insulation resistance : greater than 5,000 megohms. (Tested at 500 Volts D.C.).

POLARIZATION

'ent Part Nos, certain types of connectors are available with two alternative keying dispositions. This feature will -ig adjacent connectors with similar contact arrangement.

CONNECTION COUPLING SYSTEM

3-4 and 7 contacts : push-pull type.
12-19-27-37 and 55 contacts : bayonet-lock type (1/6 turn).

IHANICAL DATA

Durability : no damage after 1,000 engagements and disengagements, as in service.
vibration: Specification NF-C 20706 (International Specification : CEI 68-2-6).
