The TE Connectivity 4-640427-3 is a 13-position IDC receptacle from the MTA-156 series. It terminates discrete or ribbon cable via insulation displacement — no stripping, no crimping — and mates with standard MTA-156 headers.

The closed-end housing blocks the last position, so you cannot accidentally push a contact past the back wall. Wire gauge is 20 AWG, and the cable termination is IDC: the contact beam slices through the insulation and grips the conductor in one press stroke.
