4.20mm pitch, 8-position VAL-U-LOK header with board lock
The 1586040-8: This is a vertical through-hole header from the VAL-U-LOK series, 8 positions loaded in two rows at 0.165" (4.20mm) pitch. It mates with standard VAL-U-LOK receptacle housings that accept the matching crimp terminals — a common wire-to-board interconnect for moderate-current harnesses in industrial and lighting applications. Four-wall shrouding and a locking ramp on the top surface provide polarisation and audible latch retention when mated — the ramp clicks into the receptacle's matching window.
Board lock anchors the header during reflow and service
This is useful in any build where the wire exits the connector under tension or the assembly sees vibration.
