This housing ships without contacts. The spec line is explicit: Contacts Not Included. The housing accepts the standard VAL-U-LOK crimp pin, which terminates 18-24 AWG wire. Without the terminals, the housing is an empty shell — don't order half a connection.
14 positions, dual-row, 4.20mm pitch
The 14 positions are arranged in two rows with a 4.20mm pitch and 4.20mm row spacing. This is the same footprint as the 10-position sibling 1-1586017-0 — just with four more cavities. The latch lock differs from the locking ramp used on the 1-1586000-4 and 1-1586000-6 siblings — same series, same pitch, same material, but a different retention mechanism. If your application calls for the locking ramp style, the 1-1586000-4 (14-position) or 1-1586000-6 (16-position) are the direct alternatives.
Free-hanging, crimp termination, latch lock
Free-hanging (in-line) mounting means this housing is designed for wire harnesses — no PCB footprint needed.
