The 1-917658-5: 12 positions in 2 rows at 5.08 mm pitch — the footprint is a standard 0.200-inch grid with 7.62 mm row spacing. That matches the Dynamic D-3200 receptacle footprint exactly.
Shrouded 4-wall with detent lock
The 4-wall shroud and detent lock keep the header mated under vibration — the shroud guides the receptacle home, the detent holds it. No secondary latch needed for most industrial cabinets.
The tin-plated contacts (78.7 µin on mating surface) suit moderate-cycle industrial duty.
