The MDM-37PBSP is a 37-contact Micro "D" metal shell connector designed for reliable interconnection in demanding environments. It features a pin gender configuration with gold-plated copper alloy crimp contacts, an aluminum shell with yellow chromate/cadmium over nickel finish, and straight PCB termination for direct board mounting. The connector is rated for 3 A maximum current and 600 VAC dielectric withstanding voltage at sea level, with contact resistance of 8 milliohms maximum and insulator resistance exceeding 5000 megohms. It incorporates jackscrew coupling and is qualified for thermal shock (-55°C to +125°C), physical shock (50 G's), vibration (20 G's, 10-2000 Hz), and 500 mating/unmating cycles. This connector is ideal for aerospace, military, and industrial applications requiring robust, high-density signal and power distribution.
