It uses a 0.020" (0.50mm) pitch in a 2-row layout with center strip contacts, keeping the mated pair slim for tight stacking envelopes. Gold contact finish is standard, suited for the moderate mating cycles typical of internal device interconnects.
Stack height range and board layout
This receptacle supports mated stacking heights of 4mm, 4.5mm, 5.5mm, and 6mm, giving the board designer flexibility to pick the gap that fits the component height on the opposite board. The 0.50mm pitch demands careful trace routing — expect to use micro-vias or blind vias for dense fan-out on inner layers. The 50 positions at this pitch are typical for parallel display or sensor interfaces where signal count is high but board real estate is tight.
