Amphenol Limited Copper Alloy Straight 37 Way Panel Circular Connector Female 5A 550V MIL-DTL-38999 Series D38999/20FD35PN

Amphenol Limited D38999/20FD35PN is a high-performance circular connector engineered to meet MIL-DTL-38999 Series III standards. This 37 Way Panel Circular Connector features a straight orientation, female connector shell with male contacts, and is constructed from durable Copper Alloy and Aluminium materials. It is designed for harsh environments typical in military, aeronautic, advanced industrial, and electronic applications requiring robust and reliable connectors.

The connector supports an operating current of 5 Amps and voltage rating of up to 550 Volts, making it suitable for a wide range of power and signal transmission requirements. Its compact D15 shell size and subminiature connector size facilitate use in space-constrained panel mount installations.

Key mechanical features include crimp termination type for secure wire connections, a self-locking mating system to ensure reliable fastening and contact integrity, and an operating temperature range from -65°C to 200°C to withstand extreme environmental conditions.

The housing is made of aluminium with an electroless nickel plating that provides excellent corrosion resistance and durability, while the contacts are copper alloy plated with gold to ensure optimal electrical conductivity and minimized contact resistance. The connector also incorporates strain relief for cable protection against mechanical stress.

This circular connector is ideally suited for use in industrial manufacturing, military-grade electronic equipment, aerospace systems, and other demanding environments where superior connector performance and reliability are critical.
