MIL-C-26482, Series 2 Connectors PV Intermatable with MIL-C-26482 Series I Operating termperature - 55C to + 200C 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 4 1 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 Min- uteman, Skylab, Thor-Delta, Titan IIIC, and Viking. 3 The PV series is an important member of the Universal Interconnect System (UIS) - the only system that can perform all interconnection mis- 2 sions. This system is adaptable for use with connec- tors of all shapes and sizes, including circular and Universal Insertion / Extraction Tool Style - A rectangular configurations. standard, miniature and single,expendable plastic tool is used for insertion and subminiature sizes. UIS is a rear servicing system extraction of both pins and sockets. that evolved from the LITTLE CAESAR rear re- lease contact retention assembly, pioneered and developed by ITT Cannon.
