Product details

Board-Stacking Fit: What the 0.40mm Pitch and 0.80mm Height Mean

The Hirose BM20B(0.8)-10DS-0.4V(51) is a 10-position receptacle from the BM20 series, designed for parallel board-to-board stacking where the gap between PCBs is tight.

This 10-position receptacle shares the same 0.016" (0.40mm) pitch and 0.031" (0.80mm) stack height with the 34-position BM20B(0.8)-34DS-0.4V(51). Both use gold-plated center strip contacts with 2.00µin (0.051µm) thickness and the same solder retention feature for SMT reflow stability.
