Mating pin length is 0.130\" (3.30mm) and the post length is 0.075\" (1.91mm), which together define the stack height between boards.","metaTitle":"87402-120LF Amphenol FCI Rib-Cage™ 40-Position","metaDescription":"87402-120LF: 40-position, dual-row 1.27mm pitch board-to-board header, gold/GXT mating contacts, right-angle through-hole, active production.
