The 5102321-4: The latch lock/eject hooks on the long sides provide a positive mechanical lock; when the mating housing clicks in, the hooks resist vibration-induced separation and also act as ejectors for un-mating. The keying slot and mounting flange on the header body prevent mis-mating and give a secondary anchor point to the panel or PCB for strain relief.
The post tails are tin-plated (100.0 µinch) for good solderability to the PCB.
The mating pitch is 0.100" (2.54 mm), and the row spacing is also 0.100" (2.54 mm). This is the standard pitch for AMP-Latch ribbon-cable IDC connectors.
Yes, it is a shrouded header with a 4-wall shroud. The fastening type is latch lock/eject hooks on the long sides — these provide a positive lock and also act as ejectors for un-mating.
