The TE Connectivity MTA-156 4-640426-0 is a 10-position single-row receptacle that terminates 18 AWG discrete wire through an IDC (insulation displacement) slot — no stripping, no crimping, just push the wire in and the contact blades cut through the insulation. The 0.156" (3.96mm) pitch matches the standard MTA-156 header footprint, so this receptacle locks onto the mating pin header with a locking ramp that holds under vibration. The closed-end housing means the IDC slots stop at a solid back wall — the wire can't push through the back during assembly.
No crimp, no solder — just a straight push and the connection is made. The closed end prevents the wire from exiting the back of the housing, so you get a clean stop every time.
Where this fits in the harness
The 10-position count is common for multi-wire signal or low-power distribution in appliances, HVAC controls, and industrial panels. The 0.156" pitch gives more room between contacts than a 0.100" IDC connector — easier to route individual 18 AWG wires without crowding.
