The 0.156\" (3.96 mm) pitch matches the standard MTA-156 header footprint, making it a direct wire-to-board interconnect for power distribution or signal harnesses in appliances, HVAC, and industrial controls. The closed-end housing prevents wire over-insertion, and the orange colour aids visual line identification on the harness board. This speeds harness assembly and reduces inventory of loose contacts. The free-hanging (in-line) mount suits it for cable-to-board runs where the receptacle floats on the wire bundle. Contacts are tin-plated with a thickness of 80.0 µ\" (2.03 µm). The thick finish provides better corrosion resistance than a flash coating, relevant for non-sealed environments with moderate humidity. ## Locking Ramp Retention This prevents accidental disconnection under vibration — common in appliance and HVAC fan assemblies where the harness sees movement during shipping or operation.","metaTitle":"TE MTA-156 4-640426-4, 14 Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 IDC receptacle, 14 circuits, 0.156\" pitch, tin-plated contacts, locking ramp.
