General
Information
5 & 6 Contact These connectors are universally used in communications equipment where
10 Contact the highest reliability is needed under the most severe environmental
conditions. The standard 5-contact connectors meet all requirements of MIL-
C-55116, latest revision. 6-contact connectors as well as the light-weight
versions are designed to meet all performance requirements of MIL-C-55116.
Mating is accomplished quickly with a twist-lock motion. Non-rigid contacts
are spring loaded and provide positive electrical connection with minimum
voltage drop.
The 10-contact connectors conform to MIL-C-10544, latest revision.
Construction and mating action are similar to the 5-contact line. Years of
successful field experience have proven the remarkable reliability of this line
of connectors for all types of military and commercial communications
equipment.
