Board footprint and circuit count for the BOM
The 3-534236-0: The 0.100" row spacing matches the mating pin header, so the PCB layout is a simple 2×30 grid of 0.040" plated-through holes.
Gold mating surface and cycle life
The mating contact finish is 30.0 µinch (0.76 µm) gold over phosphor bronze — that thickness is rated for 500 mating cycles minimum in the AMPMODU Mod II series.
The base product number is 534236; the full 3-534236-0 suffix specifies the 60-position, dual-row, through-hole variant with gold mating finish and tin-lead post finish.
