MDM-31PCBRL56-A174 is a 31-contact Micro-D PCB connector designed for high-density, high-reliability board-to-board, board-to-cable, and cable-to-cable applications. It features pin (plug) contacts with 0.050" contact spacing, right-angle board mount termination, and an electroless nickel shell finish (A174). The connector utilizes a Liquid Crystal Polymer (LCP) insulator material and offers dimensions including A Max of 2.040 inches (51.82 mm) and B of 1.800 inches (45.72 mm). It is rated for dielectric withstanding voltage of 600 VAC at sea level, insulation resistance of 5,000 megohms minimum, and can withstand thermal shock from -55°C to +125°C. This connector is ideal for flex circuitry, flat cable, and printed circuit board applications requiring miniature, robust interconnect solutions.
