0.156" Pitch IDC Receptacle, 4 Positions, 18 AWG
The TE Connectivity MTA-156 3-641217-4 is a 4-position IDC receptacle built for discrete or ribbon cable harnesses. Termination is insulation-displacement — the 18 AWG wire is pressed into the contact slot without stripping or crimping, which speeds harness assembly when the wire gauge is fixed. The housing is orange, a visual key common in the MTA-156 family for quick identification on the line. A closed-end design means the wire stops at the back of the slot, giving consistent insertion depth across all four positions.
