The MS3106E16-10S is a military-grade circular connector socket designed for reliable electrical connections in demanding applications. It features a straight plug shell style with threaded coupling and endbell with clamp and bushing, accommodating 3 contacts of size 12 with hard silver plating and solder cup termination. The connector is constructed from aluminum alloy with olive drab chromate coating over cadmium plating, neoprene insulator and gromet material, and copper alloy contacts, ensuring durability and corrosion resistance. Key electrical specifications include a contact rating of 41 A at +20°C, contact resistance of 3 mO, test voltage of 1600 Vrms, and insulator resistance exceeding 1000 MO. The connector operates reliably across an ambient temperature range of -55°C to +125°C, maintains IP65 protection rating, and demonstrates 500-hour salt spray resistance with a minimum of 500 mating cycles. This connector is ideal for aerospace, military, and industrial applications requiring robust, high-reliability interconnections in harsh environments.
