80-Position Density on 1.27 mm Pitch
The 20021111-00080T8LF: The 80 circuits pack into a board footprint roughly 1.0 inch long by 0.1 inch wide — the routing density demands a fine-trace PCB, but the through-hole termination keeps the mechanical anchor solid. The 1 A ceiling is typical for a 1.27 mm pitch signal header — the fine contact beam and narrow pitch limit current per circuit, so this is a signal interconnect, not a power bus.
In a board-to-board application where the header is mated once at assembly and rarely cycled, the gold provides corrosion resistance and low contact resistance for the life of the product.
