What this 60-position header is built for
The 5-104894-6: The 0.050" (1.27 mm) pitch and right-angle SMT orientation let you route signals parallel to the PCB, keeping the z-height low in tight enclosures.
Insulation height of 0.213" (5.40 mm) sets the mated stack height; confirm your receptacle's mating depth to avoid interference with adjacent boards.
Current rating and signal duty — it's a signal connector, not a power bus
The 60 circuits at 0.5 A each sum to 30 A total across the connector, but the limiting factor is the per-contact temperature rise, not the aggregate. In a typical 3.3 V logic chain, the voltage drop across the contact is negligible.
