What this 4-position header does in the Universal MATE-N-LOK family
For a power-distribution or signal interconnect inside an enclosure that gets mated once at build and maybe again at service, tin is the right call.
Pitch, positions, and what mates with it
At 4 circuits and 6.35 mm pitch, this header mates with the corresponding Universal MATE-N-LOK receptacle housing and crimp terminals — the same 6.35 mm centreline. The single row means you're looking at a 4-position cable assembly that plugs straight in. Compared to a 12-position dual-row sibling like 1-2823056-2 at 2.54 mm pitch, the 350761-4 trades density for easier hand-wiring and higher per-contact current headroom.
