What This Header Does in the Board Assembly
The 22-28-1041 is a 4-circuit, right-angle pin header from the Molex KK 100 family. The friction lock ramp on the shroud holds the mating receptacle in place against light vibration — a simple, audible latch that prevents the connector from walking apart on the board edge. The 15 S tin plating on the contacts suits moderate mating-cycle duty (typically 25-50 cycles) in a clean, indoor environment.
