4-position power header with a locking ramp
The 641968-1 is a 4-position, single-row header from the Universal MATE-N-LOK series, rated 12 A per circuit at 600 VAC. The locking ramp on the shroud keeps the mating connector from backing out under vibration — a real advantage in a power distribution harness where a loose connection means a hot joint.
The 6.35 mm pitch and 4-position count are the footprint anchors. The board guide feature helps align the header during wave solder, reducing tombstoning risk.
