Mini Clamp Socket IDC Connector 3M 37308-3163-0W0 FL Compact Design for Board and Panel Space
Product Overview
The 3M Mini-Clamp Socket, 373 Series, is an IDC (Insulation Displacement Connector) designed for wiring applications, particularly for components supplied from Japan and Asia. It offers a 2 mm pitch and supports both wiremount and panel mount configurations. Key advantages include no special wire preparation required, integrated cable retention, and debris-free wire termination. The design accepts multiple wire size diameters and plug latches for reliable interconnections in demanding applications, contributing to a high number of mating cycles. Its compact design saves board and panel space, and the product helps reduce maintenance work by providing higher connection reliability.
