The 10 positions are arranged in two rows of five, so the mating header will have a matching 2x5 layout at the same 3.96mm pitch. The row spacing of 4.60mm means the header's two rows of pins are that distance apart — check your board layout if you're designing the footprint from scratch. The latch lock fastening is the primary retention: it's a molded ramp on the plug that snaps over a catch on the header. It holds against vibration better than a friction-only fit, but it's not a secondary lock — if the harness sees heavy shock, you may want to add a cable tie or clamp behind the housing.
The housing itself is free-hanging, so no board mount is involved on this half. The mating half is a Power Double Lock header (through-hole or right-angle, depending on your board layout) with the same 10-position, dual-row, 3.96mm pitch configuration. For field service, this means you can re-pin the harness on site with a basic crimp tool — no soldering, no special fixtures.
It's RoHS compliant. If you're filling a BOM line, confirm the position count and the mating header part number before committing.
