Board-fit and orientation
The 2318770-4 is a 4-position, 5.00 mm pitch header from the WireMate series, terminated by right-angle surface-mount solder tails. The 0.252" (6.40 mm) insulation height and board guide feature help align the header during pick-and-place and keep the mating face stable against the PCB. Tin contact mating finish suits moderate mating-cycle applications — the 250 V UL rating covers typical 24 VDC or 120 VAC industrial signal circuits without derating.
