What this 13-pin right-angle header does
The 6-102203-0: Its 0.100" (2.54mm) pitch sets the board footprint and the mating receptacle's contact spacing. Through-hole right-angle mounting means the header sits perpendicular to the PCB, useful for board-edge routing or connecting to a cable assembly that exits parallel to the board.
Contact plating and current rating
In a field-service application where the connector is cycled quarterly, that is decades of reliable contact.
