2-position wire-to-board header with locking ramp
Tin-plated phosphor bronze contacts handle the current duty; the tin finish is suitable for infrequent disconnect cycles (typically 25–50 mates before wear-through).
Pitch and board footprint — 0.250-inch spacing
At 0.250" (6.35mm) pitch, the 350759-4 occupies a board footprint significantly wider than signal-level headers (0.100" pitch). This spacing suits wire gauges up to 14 AWG in the matching receptacle, keeping the per-contact current ceiling around 15 A depending on ambient temperature and wire size. The single-row layout keeps the PCB keep-out zone narrow — about 0.275" wide including the housing base.
The 350759-4 mates with Universal MATE-N-LOK receptacle housings that accept crimp-socket terminals (e.g., TE 350777 series).
