VAL-U-LOK 4-Position Plug Housing — Harness-Side Half
It carries a 4.20 mm pitch and uses a latch-lock fastening system for positive retention in harness assemblies.
Contacts Are Ordered Separately — Critical BOM Note
The 1586017-4 accepts male pin crimp terminals (TE part number 1586033-x series, sold separately) that must be crimped onto 18-24 AWG wire before insertion. A common sourcing miss is ordering only the housing and discovering the harness cannot be terminated. Stock both halves of the mating pair and the terminals together to avoid an orphan plug on the shelf.
Dual-Row 4.20 mm Pitch — Compact Power Distribution
Two rows at 4.20 mm pitch give this 4-position housing a compact dual-row footprint that fits standard VAL-U-LOK headers. The 4.20 mm pitch is the same as the row spacing, creating a symmetrical grid that simplifies PCB layout for the mating header.
