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 126 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 Operating Temperature Range cycles for RFI plug (MS3475) and 500 cycles for standard Classes A, L and S*: -55C to +200C (-67F to +392F) plug (MS3476).
