4.20mm pitch, 6-position, 9A — wire-to-board power header
This is a TE Connectivity VAL-U-LOK header, order code 1586038-6, with 6 circuits arranged in two rows at 4.20mm pitch. It carries 9A per contact at 600VAC, putting it in the mid-power wire-to-board class — not a signal header, not a high-current bus bar. The 4.20mm pitch gives you room to route 18 AWG without crowding the board. The 4-wall shrouding and locking ramp mean the mating receptacle clicks in and stays put under vibration. That locking ramp is the same interface used across the VAL-U-LOK family, so the mating half is a standard VAL-U-LOK receptacle housing with crimp terminals.
