MIL-C-26482, Series 2 Connectors
• Intermatable with MIL-C-26482 Series I
• Operating termperature - 55˚C to + 200˚C
PV
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 Min-
uteman, 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 mis-
sions. This system is adaptable for use with connec-
tors 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 re-
lease 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 in-
dustrial 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 accommo-
date the following backshells: M85049/31
(MS3416), M85049/51 (MS3418) and M85049/
52 (MS3417). Backshells are not included with
connector and must be ordered separately. Back-
shells on page 161 are Non-MS type.

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 config-
uration eliminates undercuts and maximizes bend re-
sistance 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 chaf-
ing of wire during assembly.
