It carries a 1.80 mm pitch, tin-plated copper alloy contacts rated 4 A per circuit at 350 V, and a four-wall shrouded housing with a detent lock that gives positive retention against vibration.
The 1.80 mm pitch is tighter than the 2.00 mm or 2.54 mm common on many board-to-wire headers, which means the board footprint is more compact — useful when routing density is a constraint. The 4 A per-circuit rating is the headline current, but with tin-plated contacts the practical limit for repeated mating cycles is lower than gold; this header is best suited for a one-time or infrequent mate in a harness assembly, not a field-service disconnect cycled daily.
The red insulation colour is consistent across the SFH series, making visual identification straightforward on a populated board.
