Amphenol MS3106A18-3S Circular Connector Receptacle

Amphenol MS3106A18-3S Circular Connector Receptacle is a two-position MIL-DTL-5015 style circular connector from Amphenol’s MS/Standard family, built around shell size 18 to deliver rugged, high-reliability interconnections in aerospace, defense, and industrial environments where a metal, compact interface is required. This receptacle configuration provides two contact positions with solder cup terminations, enabling robust solder connections to the socket contacts and ensuring reliable mating with the corresponding plug in the same series. Part of the MS3106 family, it shares the same insert arrangement and shell size as other MS3106 configurations and is designed to withstand vibration and temperature variations that are typical in MIL-spec applications. The 18 shell size specified by MS3106A18-3S corresponds to a defined outer dimension and mounting footprint, intended for use where standardization across equipment and components is critical.
