The closed-end orange housing gives a positive wire stop, preventing the conductor from pushing past the contact zone during assembly. Rated for 18 AWG wire — the IDC slot is tuned to that gauge. Using a thinner or thicker wire risks an unreliable connection or insulation damage. ## Termination and Harness Assembly IDC termination means the wire is pressed into insulation-displacement slots — no stripping, no crimping. For a harness builder, this translates to faster assembly on a bench press or automated tooling, provided the wire is the correct 18 AWG. The free-hanging (in-line) mount is typical for a cable-to-board interconnect; the receptacle stays on the wire harness and mates to a right-angle or vertical header on the PCB. The closed-end feature also prevents the contacts from being damaged if the wire is pushed in too far — the back wall stops it at the right depth.","metaTitle":"TE Connectivity 3-641148-4 MTA-156 Receptacle, 4 Pos, IDC","metaDescription":"TE 3-641148-4 MTA-156 IDC receptacle, 4 positions, 0.156\" pitch, gold contacts, locking ramp.
