MS3112E16-8P is a miniature cylindrical box mounting receptacle connector designed for reliable electrical connections in compact applications. This connector features a shell size 16 with 8-pin solder contact configuration and operates under MIL-C-26482, Series 1 bayonet coupling specifications. The receptacle is rated for 5.0 amperes per #20 contact and supports dielectric withstanding voltage of 1500 volts (RMS) at 60 Hz for Service Rating I, with optional higher ratings available. It includes an open wire seal (Class "E") configuration and is constructed with tin-plated contacts for corrosion resistance. The connector is commonly used in aerospace, military, and industrial applications where miniaturized, high-reliability interconnections are required in space-constrained environments.
