The closed-end housing has a solid back wall that prevents the cable or individual wires from pushing through the connector during IDC termination — a practical stop for the harness builder.
Termination is insulation-displacement (IDC), so you press the wire into the slot rather than crimping a separate terminal. The slot blades cut through the insulation and make contact with the conductor in one operation. The wire gauge range is 26-30 AWG, which covers common signal-level wiring for ribbon cable and discrete harnesses. The free-hanging mounting style means the receptacle sits in-line on the cable, not on a panel or board.
Where This Connector Fits in a Harness
The 5-position count suits low-pin-count signal runs — think sensor cables, encoder feedback, or control wiring inside an enclosure. The black housing is a visual identifier but has no electrical function. The connector accepts discrete or ribbon cable, giving the harness builder flexibility: use ribbon for a tidy parallel run or discrete wires for a point-to-point loom.
