Product Description

Amphenol Industrial MS3106A-28-21S is a MIL Spec Circular Connector engineered for high durability in industrial, military, and demanding commercial environments. This connector features a cable-mounted, straight shell design with 37 female contacts made from copper alloy with silver plating, providing both reliable electrical conductivity and corrosion resistance for challenging applications like power distribution, testing, and ground support.

The shell is manufactured from robust aluminium alloy and finished with electrically zinc-plated olive drab chromate, delivering enhanced strength and long-term performance. The connector uses a screw coupling mechanism and single key/keyway shell polarization, assuring secure, accurate mating and preventing misalignment. The resilient synthetic rubber inserts offer high dielectric strength and vibration resistance, crucial for equipment operating in environments subject to mechanical and physical stress.

With a voltage rating of up to 700V AC and a current rating of 5A, the MS3106A-28-21S is suitable for a broad range of communication, control, and power applications. The IP67 rating certifies the connector against dust and water ingress, enabling installation in industrial sites and shipboard systems where exposure to harsh elements is expected. The product conforms to MIL-DTL-5015 military standards, guaranteeing reliability and compatibility with a range of MS Series receptacles (3100, 3101, and 3102).

Installation is streamlined thanks to the cable-mount, straight orientation and strain relief features which ensure cable integrity and stability under continuous use. Operating temperature ranges from -55°C to 125°C, making it suitable for outdoor and demanding indoor environments. The connector accommodates solder termination for secure and consistent electrical joints.

Typical applications include communication equipment, industrial controls, shipboard installations, testing laboratories, and ground support systems. Its modularity and durability make it ideal for equipment assemblies where performance and reliability are critical.
