MTA-156 IDC Receptacle, 9 Circuits, Closed End
The TE Connectivity MTA-156 3-640429-9 is a 9-position IDC receptacle in the MTA-156 series, designed for mass-termination of 24 AWG discrete or ribbon cable. The 0.156" (3.96mm) pitch matches the standard MTA-156 header footprint, and the closed-end feature blocks the last position to prevent a one-off cable insertion error.
IDC Termination and Wire Handling
This connector terminates via insulation displacement — no crimp tool, no loose terminals. The 24 AWG wire gauge is fixed by the slot geometry; the wire type is listed for discrete or ribbon cable, meaning the same housing works for both a point-to-point harness and a ribbon-cable assembly. The closed end forces the cable to load from the open side, which is a deliberate orientation key — you cannot insert the cable backwards or one position off.
Locking Ramp and Free-Hanging Mount
Mates with the standard MTA-156 pin header (0.156" pitch, single row).
