Audio General Information 5 & 6 Contact Audio 10 Contact 6 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 MILC-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. 5 & 6 Contact Materials & Finish Shells Panel Nuts Contacts Insulators Stainless steel, passivated, sand-blasted.
