Reduce wiring time by 80%

3M™ Mini-Clamp III Series’ IDC termination technology helps reduce wiring time by 80% compared to crimp-style connectors* while also helping to reduce waste produced from wire stripping. Use the 3M™ Mini Clamp Connector Hand Tool for bulk installations, or standard pliers for smaller installations.

  • Better connections all across the system

    The 3M™ Mini-Clamp III Plug 37A Series offers a reliable termination solution for a variety of applications including wire-to-wire and wire-to-board connections. You can keep installation costs low and help reduce waste when combining with other 3M IDC connectivity solutions such as 3M™ Link Connectors. Wire termination with 3M IDC technology is quick and reliable when compared with traditional crimp-style methods.

    3M™ Mini-Clamp III Plug 37A Series support wire sizes ranging from 30 AWG to 20 AWG.  This versatility across just three connector sizes (for the same number of positions) enables streamlined inventory.

    It’s also easy to mate the connectors: an audible click sound will verify a secure plug-to-socket connection. The compact design of the connectors, with only a 2mm pitch, makes them ideal for solutions where wire routing and board space is limited.
