What this connector is
The 95687-122HLF: Contacts are phosphor bronze with 30.0 µin (0.76 µm) gold or Gold GXT plating on the mating interface. All 22 positions are fully loaded.
Electrical and mechanical ratings
Rated 5 A per circuit at 110 V — that voltage ceiling suits industrial signal and low-power distribution rails, but rules this part out for any circuit running above 110 V. The 5 A per-contact rating holds at standard temperature; derate per the derating curve in the product drawing if the local ambient runs hot. The UL94 V-0 insulation material rating means the housing passes the most demanding industrial flammability test — relevant for enclosed panels and any UL/CE-designated equipment. Insulation height is 0.100 inch (2.54 mm), matching the pitch — for mezzanine or perpendicular board-to-board stacking, this sets the standoff in the mated pair. The post extends 0.360 inch (9.14 mm) below the shoulder, giving adequate solder fill depth for a reliable through-hole joint. Overall contact length is 0.820 inch (20.83 mm). Unshrouded — there is no polarizing keying tower on this variant, so mis-mate risk falls on the mating half's keying design and the board layout's pinout discipline. If keyed insertion is required, confirm the receptacle housing carries the polarizing feature.
Where it is used
Board-to-board header in industrial automation, process control, and instrumentation equipment — the 0.100-inch pitch is the dominant interconnect grid for PLC backplanes, I/O modules, and motor drives where board-to-board signal and low-level power pass through a fixed-stack footprint. The through-hole mount handles vibration environments better than SMT alone. The 5 A rating covers relay coil drives and sensor bus power in addition to pure signal.
