MDM-51PCBRM7TL61-A174 is a 51-contact Micro-D PCB connector designed for high-density board-to-board, board-to-cable, and cable-to-cable applications. This plug connector features a condensed right angle (CBR) termination type with a 0.100" x 0.100" thru-hole staggered grid pattern and 0.050" contact spacing. The connector utilizes a Liquid Crystal Polymer (LCP) insulator material and includes M7 jackpost mounting hardware with an electroless nickel (A174) shell finish. 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. Common applications include flex circuitry, flat cable, and printed circuit board interconnections where high reliability and miniature form factor are required.
