Product details

The DF40HC(4.0)-40DS-0.4V(70): The 4mm mated stacking height sets the z-axis clearance between parallel PCBs. The connector body stands 0.154" (3.90mm) above the board surface. For applications needing a tighter gap, the DF40 series offers a 3.40mm stack height variant — the DF40HC(3.5)-40DS-0.4V(51) — which shares the same 40-position, 0.40mm pitch footprint but reduces the board-to-board spacing by 0.60mm.

Position Count and Series Fit

Siblings include a 60-position variant (DF40HC(4.0)-60DS-0.4V(51)) and an 80-position version (DF40HC(4.0)-80DS-0.4V(51)), all at the same 0.40mm pitch and 4mm stack height.

Mating Interface and Contact Finish

The center strip contact design provides a broad wiping surface during mate, which helps maintain contact resistance over repeated insertions.
