MS circular connectors meet the performance requirements of MIL-DTL-5015 specifications while providing cost-effective, well-proven electrical capabilities in critical equipment. MIL-DTL-5051 spec connectors feature threaded couplings and single key/keyway polarization to simplify installation and design.
Class E MIL-DTL-5051 spec connectors are designed with environmental resistance and strain relief for use in applications where the connector is exposed to moisture, vibration, and rapid changes in pressure and temperature.
This MS spec box mounting receptacle (Alternate Part# 3112E123S) is a three-position, straight circular connector with a number 12 shell size and 16 AWG socket size.
- High-grade aluminum shell construction with electrically conductive cadmium-plated finish
- Silver-plated, copper alloy pin and socket material
- Neoprene inserts offer a high dielectric strength and arc resistance while resisting vibration
- Strain-relief clamp reduced tension at the solder connection providing a positive mechanical seal
- Completely field serviceable provided with the strain relief clamp
