CONNECTORS, ELECTRICAL, (CIRCULAR, ENVIRONMENT RESISTING), RECEPTACLES AND PLUGS, GENERAL SPECIFICATION FOR

Year: 2009

Abstract: This specification covers the general requirements for environment resisting, circular, electrical connectors and their associated contacts and accessories. These connectors must utilize crimp or solder contacts and be capable of operation within the specified range.Intended Use: a. Connector backshells must be installed to meet the specified moisture sealing requirements. b. Class G connectors are stainless steel connectors intended for use in environment resisting applications that require a peripheral shield, 200ºC (392ºF) service temperature, and fluid resistance. c. Class R connectors are intended for use in environment resisting applications at 200ºC (392ºF) service temperature. They have conductive finish with fluid resistance requirements. d. Class H receptacles are intended for use in applications where pressures must be contained by the connectors across walls or panels on which they are mounted. They must have fluid resistance insert face seal. Class H receptacles are limited to 150ºC (302ºF) service temperature. e. Class S connectors are intended for use in firewall applications where RFI protection is required. These connectors have self-locking coupling nuts, which eliminates the need for safety wiring and are rated at 200ºC (392ºF) service temperature. f. Class A connectors are intended for use in applications where a conductive shell is not required. Class A connectors also provide excellent durability and resistance to salt spray. g. Class K connectors are intended for use in firewall applications where RFI protection is not required. Class K connectors are available with self-locking coupling nuts. h. Series II receptacles are to be used for maintenance replacement purposes only. i. Series II plugs are to be used for maintenance replacement purposes only. j. Mechanical strain reliefs are intended for use where a saddle type clamp is desired. k. Shrink strain reliefs are intended to provide wire support and vibration dampening when used. l. To remove unwired contacts, contact contractors for specific tools and instructions. m. Class Y receptacles are intended for use in applications where pressures must be contained by the connectors across walls or panels on which they are mounted. They must have fluid resistant insert face seals. Class Y receptacles are rated at 200ºC (392ºF) service temperature. n. Type T threaded are intermateable but not completely interchangeable with applicable MIL-DTL-26500 threaded connectors except for shell size 8. Type B bayonet connectors are completely interchangeable with applicable MIL-DTL-26500 bayonet connectors. o. Class N connectors are for the same use as class S or Y except they have electrodeposited nickel finish. p. Classes M, T, W and Z connectors are intended for use in environment resisting applications at 175ºC (347ºF) service temperature where extreme corrosion resistance requirements exist.
