MDM-37SBSPTL61 is a 37-contact socket (receptacle) Micro-D PCB connector from ITT Cannon's MDM-PCB series, designed for high-density and high-reliability interconnect applications. It features a straight PCB termination (BS), jackpost mounting hardware (P), threaded inserts (T) with #2-56 thread, and a modified termination tail length of 0.125 inches (3.18 mm) per the L61 code. The connector utilizes a Liquid Crystal Polymer (LCP) insulator and a standard metal shell with yellow chromate/cadmium over nickel finish. It is rated for 600 VAC dielectric withstanding voltage at sea level, 5,000 megohms minimum insulation resistance, and supports 500 mating cycles. Common applications include flex circuitry, flat cable, printed circuit boards, and multi-layer boards in board-to-board, board-to-cable, and cable-to-cable configurations.
