4-Position IDC Plug for 16 AWG Discrete Wire
The 0.200" (5.08mm) pitch matches the standard Commercial MATE-N-LOK receptacle footprint, so the board layout or mating half is fixed once you commit to this spacing. Tin-plated female sockets are rated for low-cycle, indoor-duty harnesses — the tin finish will fret under vibration or repeated mate/unmate cycles, so this plug belongs in a permanent or infrequently serviced connection. The blue housing provides a visual key against natural or black receptacles in multi-harness panels.
The trade-off is that the wire gauge is locked to 16 AWG; you cannot step up or down without changing the connector. The feed-through feature lets you pass the same wire through multiple plugs in a daisy-chain, which simplifies multi-drop sensor or power-distribution harnesses where each drop needs a local disconnect.
