Amphenol 3106A-18 MS Circular Military Connector Shell

Amphenol MS3106A18 shell is a straight-plug, MIL-DTL-5015 circular connector housing in shell size 18, built from aluminum alloy for rugged service in demanding environments. As a shell component, it provides the external housing and mating interface for MS3106A inserts and contacts and must be paired with the appropriate insert arrangement and a coupling mechanism to form a complete connector assembly suitable for harsh military and aerospace applications. Typically used in rugged field deployments, the MS3106A family is known for reliable performance in aviation, defense, and industrial systems, and this 18-size shell is designed to accept standard MS3106A inserts with mating hardware, aligning with the broader Amphenol MS series. Common applications include power and signal connections in aircraft, armored vehicles, and rugged equipment where MIL-DTL-5015 connectors are preferred due to durability and resistance to shock, moisture, and temperature extremes.
