MDM-51PBR-2 is a 51-contact Micro-D PCB connector featuring a right angle (BR) termination configuration with pin contacts for high-density interconnect applications. It utilizes a standard MDM metal shell with Liquid Crystal Polymer (LCP) insulator material and offers 0.050" (1.27 mm) contact spacing for compact designs. Key dimensions include A Max of 1.875" (47.63 mm), B of 1.600" (40.64 mm), and C of 1.215" (30.86 mm). The connector is designed for use with flex circuitry, flat cable, printed circuit boards, and multi-layer boards, providing high reliability in board-to-board, board-to-cable, and cable-to-cable applications. It meets rigorous environmental specifications including thermal shock from -55°C to +125°C, vibration resistance up to 20 G's, and dielectric withstanding voltage of 600 VAC at sea level.
