It's a board-to-board interconnect on the classic 0.100" (2.54mm) pitch, terminated through-hole with solder.
The 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing are the standard DIP footprint — the same spacing as legacy through-hole ICs and proto boards. The 0.430" (10.92mm) mating pin length gives enough reach to engage a standard socket strip, and the 0.200" (5.08mm) post length suits a typical 1.6mm PCB.
It has 24 positions in two rows, all loaded.
It is a through-hole solder termination header.
It is an unshrouded header — no shroud, no keying, push-pull mating.
It is rated 5A per circuit at 110V.
