Amphenol MS3102A Box Mount Receptacle Connector

The Amphenol MS3102A Box Mount Receptacle Connector is a rugged MIL-DTL-5015 circular connector designed to be mounted directly to equipment boxes and panels. As the box-mount receptacle variant of the MS3102A family, it provides a mating interface for corresponding MS3102A plugs and inserts, with configurations that accommodate a range of contact counts and polarizations depending on the shell size and insert arrangement. Box-mount variants typically feature a polarized, keyed shell to ensure correct mating with the corresponding plug and are attached to the equipment enclosure with mounting hardware integrated into the shell. These box mount interfaces are used in aerospace, defense, and industrial equipment where a reliable detachable connection is required, and the circular metal shell houses the insert assemblies that carry the electrical contacts. When selecting a specific MS3102A box-mount receptacle, you’ll encounter variants with different insertion configurations; consult the manufacturer’s catalog for the exact pin count, contact arrangement, shell size, and finishes for the variant you need.
