It uses female sockets in a standard DE-9 shell layout, making it the mating half for any DE-9 male plug. The free-hanging (in-line) mounting suits cable-to-panel or cable-to-cable harness assemblies where a solderless, production-friendly termination is preferred.
The IDC termination accepts 26-30 AWG wire, which means you can terminate individual conductors directly into the insulation displacement slots without stripping or crimping — a clean, repeatable process for low-to-medium volume harness builds.
