Amphenol MS3108A20-S2P Military Circular Connector

Amphenol MS3108A20-S2P is a MIL-DTL-5015 circular connector from Amphenol's MS family, designed as shell size 20 with insert arrangement labeled A20 and configured as a 2-position socket (S2P) variant. The S prefix indicates the receptacle half, and the 2P designation confirms two electrical contacts in this version, enabling a compact two-circuit connection within a rugged circular housing. As part of the MIL-DTL-5015 lineage, this connector offers a proven MIL-spec interface suitable for aerospace, defense, and other demanding applications where reliability in harsh environments is essential. It is designed to mate with the corresponding plug half from the same family, delivering a secure connection in harness assemblies that require a compact, standardized circular interface. This MS3108A20-S2P variant is used in equipment and systems where two electrical paths must be carried through a single, standardized circular connector, benefiting from interchangeability across Amphenol's MS3108 lineup. Accessories such as mating plugs, backshells, and panel-mount hardware are commonly available for the MS3108 family to support harnessing and installation.
