26482 S 2 MIL-DTL-26482 Features and Application Series 2 Features and Application Closed-Entry Socket Insert Hard dielectric socket face has lead-in chamfers for positive alignment of pins (even partially bent within pre-established limits) with sockets. MIL-DTL-26482 Series 2, bayonet coupling, rear-removable crimp contact connectors were designed as an upgrade to Interfacial Pin Insert Seal Raised moisture barriers MIL-DTL-26482 Series 1. Series 2 connectors are intermount- around each pin, which mate into lead-in chamfers of hard able and interchangeable with both solder and front-release face socket insert, provide individual contact sealing.

Elastomer Wire Sealing Grommet Sealing over a wide Series 2 connectors are widely used on commercial, military range of wire diameters is assured by a triple wire seal in and aerospace systems requiring general-purpose, miniature each cavity at the rear of the connector. cylindrical bayonet coupling connectors. Superior Contact Stability Rear release crimp contact This family of connectors is offered in 4 receptacle-mounting system features a stamped beryllium-copper retaining clip styles. They include narrow flange wall mounting receptacles, captivated by molded-in shoulders of each contact cavity in wide flange wall mounting receptacles, cable connecting recep- the insulator. A rear-inserted M81969 plastic tool expands tacles and jam nut mounting receptacles which incorporate O the tines beyond the shoulder, releasing the contact. ring seals, designed for rear panel D hole mounting. Plugs are available in two designs, with and without RFI grounding. Thirty-three insert arrangements per MIL-STD-1669 are tooled and qualified to MIL-DTL-26482 Series 2, utilizing 3 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 passivat - ed stainless steel shells with standard environment-resisting inserts (commercial callouts only), 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. Insert Polarization Alternate insert clocking positions aid in mating of adjacent connectors having identical insert arrangement. www.conesys.com 108 sales aero-electric.com 26482 S 2 MIL-DTL-26482 Performance Specifications Series 2 Performance Specifications Durability Mated connectors withstand a minimum of 250 mating cycles for RFI plug (MS3475) and 500 cycles for standard Operating Temperature Range plug (MS3476).
