What this 2-position shrouded header does
The 4.14mm pitch (0.163") gives you room to route moderate-gauge wire without crowding the board.
The mating side of each brass pin is plated with 30µin of gold (0.76µm), which handles repeated mating cycles better than tin — expect several dozen insertions without wear-through. The solder tails get a 150µin tin finish for a reliable solder joint. The housing material (UL94 V-0 nylon) limits the temperature rise, not the contact itself.
