The red housing includes a closed end to prevent wire stubbing and a polarizing key that aligns with the matching header to prevent mis-mating. ## IDC Termination and Wire Prep Termination is insulation displacement — no wire stripping, no crimp tool. Works with discrete wires or ribbon cable; the closed end keeps the last wire from pushing through the housing. On-site re-pinning is straightforward if a terminal fails — cut the wire, strip it, and use a new receptacle if the slot is damaged. This receptacle mates with the standard MTA-156 header (0.156\" pitch, straight or right-angle, through-hole). The polarizing key on the closed end ensures the receptacle can only be inserted one way — no reversed connections in the harness. ## Contact Finish and Durability Tin is the standard for moderate-cycle applications; if the harness sees frequent reconnections or a corrosive environment, a gold-plated version of the MTA-156 receptacle would be the better call.","metaTitle":"TE MTA-156 4-643819-2 Receptacle, 12 Pos, 0.156\" Pitch, IDC","metaDescription":"TE MTA-156 4-643819-2 receptacle, 12 positions, 0.156\" pitch, IDC termination for 22 AWG wire.
