MIL-C-26482, Series 2 Connectors • Intermatable with MIL-C-26482 Series I • Operating termperature - 55˚C to + 200˚C PV www.DataSheet4U.com The PV connector is designed to meet the rugged requirements of MIL-C-26482, Series 2/MIL-C-83723 Series I*, the specification which delineates the critical requirements of space-age applications. PV connectors have been used extensively on major aerospace programs requiring general-purpose, miniature cylindrical bayonet coupling connectors such as Space Shuttle, Apollo, ATM, OWS Minuteman, Skylab, Thor-Delta, Titan IIIC, and Viking. The PV series is an important member of the Universal Interconnect System (UIS) - the only system that can perform all interconnection missions. This system is adaptable for use with connectors of all shapes and sizes, including circular and rectangular configurations. standard, miniature and subminiature sizes. UIS is a rear servicing system that evolved from the LITTLE CAESAR® rear release contact retention assembly, pioneered and developed by ITT Cannon. Since this time, ITT Cannon, and its licensees, have supplied to industry over 250 million interconnections utilizing this system. PV7 connectors are available under numerous industrial specifications, some of which are listed below: • CS512089 Jet Propulsion Laboratory • 40M39569 NASA, George C. Marshall Space Flight Center • 81D52 Martin Marietta, Denver Division • MG414-0365 Rockwell International Space Division • AC414-0013 Rockwell International Autonetics Division • STS0003 McDonnell Douglas Astronautics This connector series is manufactured to accommodate the following backshells: M85049/31 (MS3416), M85049/51 (MS3418) and M85049/ 52 (MS3417). Backshells are not included with connector and must be ordered separately. Backshells on page 161 are Non-MS type. 3 4 1 2 Universal Insertion / Extraction Tool Style - A single,expendable plastic tool is used for insertion and extraction of both pins and sockets. Simple, Strong Contact Design - One basic configuration eliminates undercuts and maximizes bend resistance for positive contact mating. Closed-Entry Socket Insert - Hard dielectric socket face of mating connector has lead-in chamfers for positive alignment of pins and sockets. Interfacial Pin Insert Seal - Universal interconnect permits design of raised moisture barriers around each pin which mate into lead-in chambers of hard face sockets insert for individual contact sealing. Interfacial sealing is never touched by service tools. Superior Contact Stability - Rear Contact Release System (LITTLE CAESAR contact assembly) features a stamped metal retaining clip captivated by molded-in shoulders of each contact cavity in the insulator. A rear-inserted plastic tool expands the tines beyond the contact shoulder, releasing the contact. Polarized Backshells - Interlocking teeth on the front of the backshell and rear portion of the shell allow endbells to be positioned as desired, eliminating chafing of wire during assembly.
