Product details

Mezzanine Stacking Specs for the BM10NB(0.8)-24DS-0.4V(51)

The Hirose BM10NB(0.8)-24DS-0.4V(51) is a 24-position receptacle with center strip contacts from the BM10 series, designed for board-to-board mezzanine stacking at a fixed mated height of 0.8 mm. The 0.016" (0.40mm) pitch and dual-row layout keep the board footprint tight, while the gold-plated contacts (2.00µin thickness) handle repeated mating cycles in compact consumer electronics, wearables, or handheld devices.

The BM10NB(0.8)-24DS-0.4V(51) sits between the 20-position BM10NB(0.8)-20DS-0.4V(51) and the 30-position BM10NB(0.8)-30DS-0.4V(51) at the same 0.40mm pitch and 0.8mm stacking height. The 24-position count matches a 24-signal BOM line without leaving unused contacts — a cleaner fit than the 20-position version for a 24-circuit board, and a smaller footprint than the 30-position alternative.
