Amphenol MS-3102A-20-21P Circular Military Connector

Amphenol MS3102A20-21P is a 21-position circular MIL-DTL-5015 connector (shell size 20) in plug configuration. As part of the Amphenol MS3102A family, this rugged metal-shell connector is designed for military and aerospace applications where reliable interconnections must withstand demanding environments. The 21 insert positions accommodate multiple conductors in a compact circular form, and the plug designation (P) identifies this half of the mating pair intended to connect with a compatible MIL-DTL-5015 receptacle of the same insert arrangement. This part is manufactured by Amphenol and adheres to the MIL-DTL-5015 family’s standard interface, ensuring interchangeability with other MS3102A components. In practical use, it supports high-reliability electrical connections in equipment such as aircraft, ground support equipment, and naval systems that rely on rigorous, field-assembled connectors.
