The 77311-824-18LF: This saves board space and allows a lower mating profile, but it also means the connector lacks keying polarization and mechanical strain relief at the mating interface. The unshrouded design is common for board-to-board stacking where the mating receptacle provides its own alignment.
All positions are loaded. The pinout is a straight row of male square pins.
This header is unshrouded — the pins are exposed with no plastic shroud around them. A shrouded header has a wall that protects the pins and provides keying polarization. The unshrouded version saves board space but offers less mechanical alignment and no polarization.
