The MDM-31PSB-F222 is a high-performance, microminiature D-sub connector designed for rugged, space-constrained environments. It features 31 pin contacts on .050-inch centers within a Liquid Crystal Polymer (LCP) insulator and a robust aluminum shell that provides EMI/RFI shielding. The terminations are solder pot style, designed to accept up to #26 AWG wire, and a silicone elastomer interfacial seal ensures moisture and humidity protection. These connectors are ideal for demanding applications in aerospace, defense electronics, and industrial automation where size, weight, and reliability are critical.
