Board footprint and mating pitch
The 5-102618-4: The shrouded 4-wall design with detent lock prevents mis-mating and holds the connection under vibration, a step up from unshrouded breakaway headers in environments where the cable gets tugged.

The 5-102618-4: The shrouded 4-wall design with detent lock prevents mis-mating and holds the connection under vibration, a step up from unshrouded breakaway headers in environments where the cable gets tugged.
The mating pitch is 0.100" (2.54mm), and the row spacing is also 0.100" (2.54mm). This is the standard 0.100-inch grid used by most AMPMODU Mod II headers and matching receptacles.
Yes, it is a shrouded - 4 wall header.
