23 circuits at 0.100" pitch — BERGSTIK II unshrouded header
Overall contact length is 0.380" (9.65mm), split into a 0.160" (4.06mm) mating pin and a 0.120" (3.05mm) solder tail. The 0.100" (2.54mm) insulation height means the header sits low on the board — the mated stack height with a standard 2.54mm female socket is roughly 0.260" (6.6mm), give or take the socket's own height. This is common for low-cost board-to-board links where the mating connector is a simple female socket strip.
