Product details

The 77311-122-12: The unshrouded design exposes the square pins, making it compatible with a wide range of IDC sockets and crimp receptacles, but provides no keying or polarization against mis-mating.

Board Fit and Mating Half Considerations

The 0.100" pitch and 12-position single-row layout set the PCB footprint. The push-pull fastening type means the connection relies on friction retention only; in high-vibration environments, a secondary locking mechanism or adhesive may be needed. The insulation height of 0.100" (2.54mm) is the same as the pitch, keeping the profile low for dense board layouts.
