What this 3-position IDC receptacle is for
The TE Connectivity 2317222-3 is a 3-circuit, single-row AMPMODU receptacle that terminates discrete or ribbon cable via IDC — no wire stripping, no crimp tool. The 0.079" (2.00mm) pitch matches standard 2mm ribbon cable, and the closed-end housing gives a positive stop so the cable seats fully every time. This is the kind of connector you reach for when you need a quick, reliable mass-terminated harness for a 3-wire signal group — think sensor leads, encoder cables, or control I/O inside an enclosure.
Rated for 26-30 AWG wire — that covers the common ribbon cable sizes for signal-level circuits. The IDC termination forces the contact through the insulation and onto the conductor; staying inside the gauge range keeps the displacement slot from either tearing the wire (too thick) or failing to pierce the insulation (too thin). The free-hanging (in-line) mount means this receptacle lives on the cable end, not on a board — it mates with a 2mm-pitch header soldered to the PCB.
