MDM-37SH003B is a 37-contact Micro "D" metal shell socket connector designed for reliable interconnection in demanding applications. The connector features gold-plated copper alloy crimp contacts with a maximum contact resistance of 8 milliohms, an aluminum shell with yellow chromate/cadmium over nickel finish, and a friction coupling mechanism. It supports a maximum current rating of 3 A and a dielectric withstanding voltage of 600 VAC at sea level (150 VAC at 70,000 ft altitude), with insulator resistance exceeding 5000 megohms. The connector is rated for 500 mating/unmating cycles and operates reliably across a thermal shock range of -55°C to +125°C, making it suitable for aerospace, military, and industrial applications requiring robust signal and power transmission.
