12-Position .070 Multilock Plug Housing — Harness-Side Connector Body
Pitch and Row Layout — What Fits on the Board or in the Harness
The 3.50mm pitch and 5.90mm row spacing put this housing in the medium-density range — tighter than a standard 0.250" power connector but roomier than a 2.50mm signal connector. That middle ground means you can run 18-22 AWG wire without fighting for cavity space, and the dual-row layout keeps the overall connector width under control for multi-circuit harnesses. Compared to the 6-position 1-1644055-3 from the same series family, the 368542-1 doubles the circuit count at the same 3.50mm pitch, so if your BOM calls for 12 circuits in a single plug body, this is the direct fit — no need to gang two 6-position housings.
Latch Holder and In-Line Mounting — Field-Ready Retention
The latch holder fastening type is the key mechanical feature here. Unlike a simple friction lock or a screw-down coupling, the latch holder engages with a positive snap that resists unplanned separation from cable tug, thermal cycling, or machine vibration. For a harness builder, that means you can route this connector through a grommet or into a junction box and trust it won't part company when the equipment starts moving. The free-hanging (in-line) mounting style confirms this is a cable-to-cable or cable-to-panel connector — no PCB footprint to worry about, just a clean wire-to-wire join.
