MDM-31SBSL61 is a 31-contact Micro-D PCB socket (receptacle) connector designed for use with flex circuitry, flat cable, and printed circuit boards. It features a standard MDM metal shell with Liquid Crystal Polymer (LCP) insulator material and straight (BS) PCB termination with an extended tail length of 0.125" (3.18 mm). The connector provides high density with 0.050" (1.27 mm) contact spacing and operates reliably across a thermal shock range of -55°C to +125°C. It offers excellent electrical performance with dielectric withstanding voltage of 600 VAC at sea level and insulation resistance of 5,000 megohms minimum. Common applications include board-to-board, board-to-cable, and cable-to-cable connections in high-reliability environments requiring compact, high-density interconnects.
