Board Layout and Mounting Reality
The 1-794108-0: This is a dual-row, 24-position header on a 4.14mm pitch — the footprint is a 2×12 grid with 4.14mm row spacing. The right-angle orientation puts the mated cable assembly parallel to the board, which matters when vertical clearance inside the enclosure is tight. Board-lock features on the through-hole tails anchor the header during wave soldering and transfer cable strain to the PCB rather than the solder joints.
Current Capacity and Contact Finish
The tin-plated mating finish (150.0µin) is rated for standard duty cycles; in a field-service application cycled quarterly, the contact interface will outlast the equipment. The brass pins with tin post plating (150.0µin) are compatible with wave-solder processes.
