Unshrouded breakaway header, dual-row 0.100" pitch
The 9-146258-0-12: Tin-plated mating contacts carry 3A per circuit; the header mates with matching AMPMODU Mod II receptacles or IDC sockets via a push-pull interface.
What the unshrouded build means for the board fit
Unshrouded headers expose the square pins for direct mating — no shroud to guide alignment, so the mating receptacle's housing takes the registration duty.
