It is unshrouded — the male pins are exposed without a plastic shroud. This mates with standard unshrouded receptacles and keeps the stack height low, but does not provide keying or polarization beyond the pin pattern.
The solder post length is 0.120" (3.05 mm). The PCB footprint is a standard 0.100" pitch header layout.
