These connectors combine the best features Closed-Entry Socket Insert Hard dielectric socket face has of MIL-DTL-26500 and NAS 1599 miniature connector lead-in chamfers for positive alignment of pins (even partially specifications. They are intermateable with both bayonet and bent within pre-established limits) with sockets. threaded 26500 connectors (exception: shell size 8, threaded coupling only) and have the added advantage provided by the Interfacial Pin Insert Seal Raised moisture barriers around rear-release contact retention system. each pin, which mate into lead-in chamfers of hard face sock- et insert, provide individual contact sealing. Interfacial seal is AE833 connectors are widely used on commercial, military never touched by service tools. and aerospace systems requiring general-purpose, miniature cylindrical bayonet or threaded coupling connectors. In Elastomer Wire Sealing Grommet Sealing over a wide addition, Series III threaded connectors with self-locking range of wire diameters is assured by a triple wire seal in each plugs are well suited for engine applications. cavity at the rear of the connector. This family of connectors (bayonet as well as threaded) is Superior Contact Stability Rear release crimp contact offered in wall mount receptacles as well as jam nut mounted system features a stamped beryllium-copper retaining clip receptacles which incorporate O ring seals, designed for captivated by molded-in shoulders of each contact cavity in rear panel D hole mounting. the insulator. A rear-inserted M81969 plastic tool expands the tines beyond the shoulder, releasing the contact. Series III bayonet-coupling plugs are available in two designs - with and without RFI grounding. Threaded coupling plugs are offered with and without RFI grounding, self-locking and RFI/self-locking. In addition we offer quick-disconnect (lanyard release) plugs, which mate with threaded receptacles via an adapter. Thirty-one insert arrangements per MIL-STD-1554 are tooled and qualified to MIL-DTL-83723 Series III, utilizing 2 to 61 M39029 contacts. Contacts come in sizes 20, 16 and 12, terminating wire sizes from 24 to 12 gauge. These connectors are available in wide range of shell materials and finishes. Aluminum shells are offered in electroless nickel, olive drab cadmium and black anodic. Other finishes such as zinc cobalt are available upon request to commercial callouts only. In addition, we offer passivated stainless steel shells with both standard and firewall-rated inserts, and for highly corrosive environments, nickel-aluminum-bronze shells with standard environment-resisting inserts (commercial callouts only). Universal I/R Tool A single, expendable plastic tool is used for both insertion and removal of contacts. www.conesys.com 127 sales aero-electric.com 83723 S III MIL-DTL-83723 Series III Performance Specifications Bayonet and Threaded Coupling Performance Specifications Durability Mated connectors withstand a minimum of 500 mating cycles for bayonet coupling straight plug (M83723/75, Operating Temperature Range 76) 250 mating cycles for bayonet coupling RFI plug Classes A and R: -65C to +200C (-85F to +392F) (M83723/77, 78) and 250 cycles for all threaded coupling Class W: -65C to +175C (-85F to +347F) plugs (M83723/86, 87, 91, 92, 95, 96, 97, 98).
