MS3102E16S-1S is a circular threaded socket connector conforming to MIL-C-5015 specifications, featuring a box mounting receptacle design with 7 size 16S solder cup contacts. The connector is constructed with an aluminum alloy shell finished in olive drab chromate coating over cadmium plating, and incorporates hard silver-plated copper alloy contacts with neoprene insulator and grommet materials. It delivers a contact rating of 22 A at +20°C, contact resistance of 6 mO, and operates reliably across an ambient temperature range of -55°C to +125°C with an insulation resistance exceeding 1000 MO and test voltage rating of 1600 Vrms. The connector provides IP65 environmental protection, 500-hour salt spray resistance, and supports a minimum of 500 mating cycles, making it ideal for demanding military, aerospace, and industrial applications requiring robust, sealed electrical connections.
