40-Position Housing for High-Density Wire Harnesses
Pitch and Row Spacing — Board Layout Fit
Both the pitch between adjacent positions within a row and the row-to-row spacing are 0.100" (2.54mm). For a 2-row, 40-position layout, the overall width across the housing is approximately 2.00" (20 positions x 0.100") and the depth across both rows is 0.100" plus the housing wall thickness. When mating with a PCB header, the board footprint will need through-hole or SMT pads on that same 0.100" grid. The dual-row arrangement doubles the density compared to a single-row 40-position housing of the same pitch.
