10.16 mm Pitch Power Plug Housing
The 3-917809-2: The 10.16 mm pitch and 0.400" row spacing give generous creepage distances for high-voltage or high-current circuits — common in industrial control cabinets, power distribution boxes, and battery interconnect harnesses where the housing carries bus-level current through the mating tab terminals. The housing accepts crimp tab contacts (sold separately), and the built-in polarizing key prevents cross-mating with other D-5200 housings of the same position count.
Panel Mount with Polarizing Key
The polarizing key ensures the plug can only be inserted one way, a practical safeguard in multi-connector assemblies where a mis-mate would short a power rail.
