The closed-end housing with a polarizing key prevents mis-mating — the key aligns with the corresponding slot on the header, so the connector cannot be inserted backwards or into the wrong circuit count. The IDC termination eliminates wire stripping and crimping, saving assembly time on multi-conductor harnesses. ## Locking Ramp and Free-Hanging Mount — Field-Ready Retention The fastening type is a locking ramp — an integral latch on the receptacle that snaps over the header's locking ramp. When mated, the latch holds the pair together against cable tug and light vibration, which is the typical duty for internal appliance wiring, control panels, and consumer electronics harnesses.","metaTitle":"TE MTA-156 4-643819-8, 18-Position IDC Receptacle","metaDescription":"TE MTA-156 4-643819-8 18-position IDC receptacle, 0.156\" pitch, 22 AWG, tin plating, locking ramp.
