Board-mount footprint and circuit count
The 1-917657-2 is a 10-position, 2-row header on a 5.08mm pitch, with a 7.62mm row spacing. The 0.200" pitch matches the standard Dynamic D-3200 receptacle footprint, so the board layout is a direct drop-in for any 10-circuit D-3200 mated pair.
Gold mating finish and board lock for industrial duty
For most industrial applications, 15.0µin gold is sufficient; the -3 is a step-up for higher-cycle or corrosive environments.
