Rated 5 A per contact at 110 V, with gold or GXT™ plating on the mating surface at 15.0 µin (0.38 µm) over phosphor bronze — the gold layer handles repeated mating cycles without fretting corrosion, while the unshrouded design keeps the profile low for tight enclosures.
The 0.100" pitch and single row mean the 32 positions occupy 3.100" of board edge — each pin drops into a 0.040" plated through-hole on 0.100" centers. The right-angle post length of 0.305" (7.75 mm) gives enough tail to clear a standard 0.062" board and still have solder fillet visible on the bottom side.
