Amphenol MS3106A28-16S Circular Connector Socket

Amphenol MS3106A28-16S Circular Connector Socket is a MIL-DTL-5015 circular interconnect in shell size 28 that serves as the female receptacle in the MS3106A family. It provides 20 contact positions configured in the 16S insert arrangement, with 20 size-16 copper contacts silver-plated for reliable conductivity. Contacts are terminated by solder, enabling permanent terminations using solder cups. The shell size 28 and 20-position insert deliver a compact, rugged connection suitable for aerospace, defense, and other environments requiring MIL-SPEC-grade interconnects. As a socket variant, it mates with the corresponding MS3106A28-16S plug, forming a durable interface when used with appropriate backshells. Typical applications include avionics, control panels, instrumentation, and external assemblies where high-density signal paths are needed in a single, rugged connector. The MS3106A28-16S is part of Amphenol's MIL-DTL-5015 standard circular connector family, offering compatibility with other MS3106A28-16S components and a broad ecosystem of mating partners and accessory options.
