It uses a 0.40mm pitch, dual-row layout with center strip contacts, and mates to a matching DF40 header to achieve a 4mm mated stack height. ## Stacking height and board spacing This is the dimension you design the enclosure or module gap around. The height above board for the receptacle alone is 3.90mm, so the header side contributes the remaining 0.10mm to reach the full 4mm stack. It protects against corrosion during storage and initial mating, but it is not built for hundreds of cycles. For a connector that gets mated once during final assembly and maybe a handful of times for rework or field service, this is fine. If you need frequent connect-disconnect in a test or calibration fixture, look for a thicker gold option in the DF40 series.","metaTitle":"Hirose DF40HC(4.0)-80DS-0.4V(51) Receptacle, 80 pos","metaDescription":"Hirose DF40 series receptacle, 80 positions, 0.40mm pitch, 4mm stacking height.
