The 4.20mm Pitch Housing That Gets Ordered Without the Contacts
The One Spec That Trips Up Every BOM Line
The listing carries the note "Contacts Not Included" — and it's the most common sourcing mistake on the VAL-U-LOK series. This housing ships as an empty shell. The 4.20mm pitch and dual-row layout match the standard VAL-U-LOK header footprint, so the board-side half is straightforward — but a BOM that lists only this housing will stall a harness build until the contacts arrive.
