The 1720641004 is a 4-position, 2-row header from the Molex Mega-Fit series, designed to carry power from a PCB to a cable assembly. The 5.70mm pitch gives you room to route wider traces on the board without crowding the adjacent circuits. It mates with a Mega-Fit receptacle housing (sold separately) and locks with a ramp latch — that latch keeps the pair together when the equipment vibrates, which is why you see this connector in automotive and industrial cabinets.
