The unshrouded design leaves the square male pins exposed, which keeps the profile low and allows easy visual inspection of solder joints, but means the pins are vulnerable to bending during handling or blind mating.
Ratings and Plating
That 5 A per pin is fine for logic-level loads, sensor inputs, and general-purpose board interconnects, but it is not a power rail rating; if you need bus-level current, step up to a heavier contact system. The mating pin length is 0.230" (5.84 mm), and the solder post length is 0.090" (2.29 mm) — the post dimension is worth checking against your PCB thickness and through-hole plating depth.
The termination is solder-only (through-hole), so it gets wave-soldered or hand-soldered into the PCB; no press-fit or compliant-pin option on this variant. The square pin profile gives reliable contact with the receptacle's twin-beam or tuning-fork contacts.
