These connectors are universally used in communications equipment where 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.
