Single-pin header for test or discrete board wiring
At 1 position, this part is not a multi-signal bus; it is a discrete interconnect point for test probes, board-edge jumpers, or single-wire power taps where the circuit count is exactly one. The gold flash on the post (contact finish thickness - post: Flash) is a thin layer for solderability, not for repeated mating; the mating face carries the thicker gold.
The connector style is listed as Board to Board or Cable, meaning the mating half can be a board-mount receptacle or a crimp-socket cable assembly. The square pin profile is standard AMPMODU Mod II — any Mod II female socket with a 0.025" square post interface will mate.
The UL94 V-0 rating is a material-level approval; the connector itself is not UL Listed as an assembly.
