MTA-156 IDC Receptacle, 5-Position, Closed End
The 0.156" (3.96mm) pitch is the standard spacing for this series, matching the footprint of MTA-156 headers. The closed-end housing acts as a wire stop, so the cable inserts to a consistent depth — critical for reliable IDC termination across all five positions. The red colour is a factory-coded identifier for the 22 AWG wire size this part is specified for.
Termination and Wire Preparation
IDC termination means the contact displaces the insulation on 22 AWG wire as the cable is pressed into the housing — no stripping, no crimping. The closed end sets the insertion depth, so the wire stops at the correct point for the contact to bite through the insulation. This works with both discrete wires and ribbon cable, making it a fast option for harness builds where the same connector serves point-to-point wiring and multi-conductor flat cable.
Contact Finish and Duty
Tin contacts are cost-effective for moderate mating-cycle counts and are common in appliance, lighting, and consumer electronics harnesses where gold plating is not required.
