The 350711-4 is a through-hole, shrouded 4-wall header from TE's Universal MATE-N-LOK series. Rated for general-purpose board-to-cable/wire applications, this header suits power distribution and signal interconnects inside industrial enclosures, control panels, and equipment where the 6.35 mm pitch allows adequate creepage for higher-voltage runs.
Pitch, plating, and locking — what drives the fit
This is a step up from friction-only headers — especially relevant in applications where the cable is subject to movement or shock. The 0.155" (3.94 mm) solder-post length is standard for through-hole boards up to 1/16" thick.
Mating connector and cross-reference
This header mates with TE Universal MATE-N-LOK receptacle housings (e.g., 350711 series) that accept crimp contacts. The 6.35 mm pitch and 3-row layout are specific to the Universal MATE-N-LOK family — confirm the receptacle's position count and row arrangement match.
