MDM-100PCBRL56-A172 is a 100-contact Micro-D PCB connector designed for high-density, high-reliability interconnect applications. It features pin (plug) contacts with right-angle board termination and a gold over nickel (A172) shell finish for enhanced corrosion resistance and conductivity. The connector utilizes a Liquid Crystal Polymer (LCP) insulator material and offers 0.050" (1.27 mm) contact spacing with a 0.100" x 0.100" grid pattern termination offset by 0.050". Key dimensions include A Max of 2.74" (69.72 mm), B of 2.500" (63.50 mm), and C of 1.800" (45.72 mm). This connector is ideal for flex circuitry, flat cable, printed circuit boards, and multi-layer board applications requiring reliable board-to-board, board-to-cable, or cable-to-cable connections.
