Plug Housing for 18-Circuit Wire Harnesses
The 1-1586018-8: It is the dual-row, 4.20mm-pitch member of the VAL-U-LOK series, a family built for reliable power distribution in automotive, industrial, and appliance harnesses.
What the 4.20mm Pitch and Locking Ramp Mean for Assembly
The panel-mount snap-in feature lets you clip this housing into a cutout in the enclosure wall, so the harness exits cleanly without a separate bracket. This is the same latch mechanism used across the VAL-U-LOK family, so any 4.20mm-pitch receptacle with the matching ramp profile will lock in.
Contacts Are Ordered Separately — Here Is What Fits
The 4.20mm pitch and dual-row layout mean each cavity accepts a standard VAL-U-LOK male pin terminal; the exact wire gauge range and current rating depend on which terminal you select. Ordering the housing alone without the contacts is a common mistake — make sure the BOM line for the crimp terminals is filled alongside this plug.
