The 0.120" post length (3.05mm) suits standard 1.6mm PCBs with room for the solder fillet on the opposite side. Mating half is any unshrouded 10-position female socket with 2.54mm pitch and 0.025" square receptacles — common choices include BERGSTIK II socket strips or generic 0.1-inch IDC connectors.
How the 30µin Gold Affects Field Duty
The phosphor bronze base metal provides good spring properties, and the gold layer prevents oxidation that would increase contact resistance over time.
Comparison with 69192-202HLF (2-Position Sibling)
The 69192-202HLF carries 15µin gold thickness (half the 30µin of the 69192-110HLF), so its mating cycle rating is lower — roughly 200 cycles vs 500.
