The red closed-end housing stops the cable at a consistent depth during IDC termination, so each conductor lands on its slot without over-insertion. IDC termination — no stripping, no crimp. The 80.0µin (2.03µm) tin finish is standard for the MTA-156 series, giving adequate corrosion resistance for indoor equipment environments. This plug mates with any MTA-156 header that has 0.156\" pitch and 4 positions — typically the TE 640441 series vertical headers or 640443 right-angle headers. Both use the same 0.045\" square pin on 0.156\" centers. The closed-end plug body does not accept a secondary TPA; the IDC retention is the only lock, so the wire must be fully seated during termination for the contact to hold.","metaTitle":"TE 3-641437-4 MTA-156 IDC Plug, 4 Pos, 0.156\" Pitch","metaDescription":"TE Connectivity 3-641437-4 MTA-156 IDC plug, 4 positions, 0.156\" pitch, 22 AWG, tin 80µin.
