Tin-plated female sockets and a locking ramp hold the mating header in place under vibration. The closed-end design blocks wire push-through on the last position. The 18-position count matches a BOM line that needs 18 circuits on a single row. The 0.156\" (3.96mm) pitch is the standard MTA-156 spacing — it sets the footprint for the mating header and the wire-to-wire spacing in the harness. The locking ramp provides positive retention against accidental unmate. The IDC termination accepts 18 AWG discrete wire; the closed end prevents the wire from exiting past the last contact. Free-hanging mounting means it sits in-line with the cable, not on a board.","metaTitle":"TE Connectivity 4-640426-8 MTA-156 Receptacle, 18 Pos","metaDescription":"TE Connectivity 4-640426-8 MTA-156 IDC receptacle, 18 positions, 0.156\" pitch, tin contacts, locking ramp.
