10.0 mm free height, stainless steel spring
The Z02L-4G7L1-11000-E000: Single-circuit compression contact with a 10.0 mm free height — the working deflection range is set by that column height; in a typical board-to-board stack-up, you design the gap so the contact compresses 20-30% for stable force. Stainless steel material gives a higher spring rate than copper-alloy pogo pins — the contact holds its normal force through repeated compression cycles without taking a set. Gold flash contact finish provides a corrosion-resistant mating surface; for a non-gendered contact that sees occasional rework, flash plating is adequate — the spring force wipes through any light oxide on each mate.
ROHS3 compliant — meets the current EU restriction on hazardous substances for electronic equipment. CT is available for prototype or low-volume builds.
