The TE Connectivity 3-641435-6 is a 6-position IDC plug from the MTA-156 series, terminated to 18 AWG discrete or ribbon cable. Tin contacts at 80.0 µin (2.03 µm) thickness handle the mechanical and electrical duty for a fixed installation where the connector mates once and stays mated; the closed-end housing prevents a terminal from being pushed past the last cavity, which is a simple polarity check during harness assembly.
No wire stripping or crimping; the tooling is a simple press. The plug mounts free-hanging (in-line) or at a right angle, which suits a harness that exits a panel edge or a board-mounted header at 90°. Mates with the matching MTA-156 header (through-hole or surface-mount, straight or right-angle) — the 0.156" pitch and single-row layout are consistent across the series.
