The B04P-VL-VN-1.8: The 20 A per circuit rating is the headline — each pin carries bus-level current, so this is not a signal header. The 6.20 mm pitch gives enough creepage distance for the 600 V rating without forcing an oversized board footprint. The UL94 V-0 nylon 6/6 housing meets the flame rating required for equipment inside an enclosure. Operating temperature from -25°C to 90°C covers most indoor industrial and appliance environments but not extended outdoor exposure.
This is a through-hole solder header — the 0.142" (3.60 mm) post length is sized for standard PCB thickness. It mates with the corresponding VL series receptacle housing (crimp terminal style). The latch holder provides positive locking; you will hear or feel it engage. The mated stacking height is 29.2 mm, so plan your enclosure z-height budget accordingly.
