At a 7.92 mm pitch, the spacing is generous — this is a power interconnect, not a signal-density part, and the wide centres give you room for larger crimp terminals and better creepage across the pair. The housing is self-mating, meaning you use the same part number on both the panel and the flying lead; no male/female halves to track, which simplifies inventory on a harness build.
Panel fit and keying — what the housing expects
This is a panel-mount housing in natural nylon, with a -40°C to 75°C operating range. The nylon body is a standard PA material — fine for dry indoor environments and general industrial enclosures, but not rated for outdoor UV exposure or sustained moisture immersion. The housing accepts non-gendered crimp contacts, which means the terminal itself is identical on both sides of the connection. The self-mating design implies the housing has a built-in polarisation feature — the two identical halves only mate in one orientation, preventing a reverse mate. There is no separate keying insert to spec; the housing geometry handles it.
