All 34 positions are loaded with square male pins in phosphor bronze, with a mating contact finish of either gold or GXT™ at 30.0 µin (0.76 µm) — a plating thickness that supports repeated mating cycles and resists corrosion in moderate environments.
The through-hole termination with a 0.110" (2.79 mm) post length is intended for standard PCB thicknesses, and the overall contact length of 0.530" (13.46 mm) gives a 0.320" (8.13 mm) mating interface — enough to reach into a standard box receptacle.
