MDM-31SCBRM7-A174-F222 is a 31-contact socket (receptacle) Micro-D PCB connector designed for high-density, high-reliability board-to-board, board-to-cable, and cable-to-cable applications. It features a metal shell with electroless nickel finish (A174), right-angle board mount termination (CBR), and grounding metal backshell (M7) for shielding. The connector utilizes Liquid Crystal Polymer (LCP) insulator material with 0.050" (1.27 mm) contact spacing and a 0.100" x 0.100" grid pattern termination configuration. Key dimensions include A Max of 1.335" (33.91 mm), B of 1.115" (28.32 mm), and C Max of 0.952" (24.18 mm). This connector is suitable for flex circuitry, flat cable, and printed circuit board applications requiring robust environmental performance including thermal shock from -55°C to +125°C and vibration resistance up to 20 G's.
