Product details

0.6mm Mated Stack – 30-Position BM20 Receptacle

The Hirose BM20B(0.6)-30DS-0.4V(53) is a 30-position receptacle with center strip contacts from the BM20 series, designed for board-to-board mezzanine stacking at a 0.6mm mated height. The 0.016" (0.40mm) pitch and dual-row layout pack 30 circuits into a compact footprint suited for space-constrained portable devices, wearables, and module-to-board interconnects. Gold-plated contacts with a 2.00µin (0.051µm) finish provide a reliable signal path for moderate mating-cycle duty.

30 vs 24 vs 20 Positions – Same Footprint, Different Circuit Count

The BM20B(0.6)-30DS-0.4V(53) shares the same 0.016" (0.40mm) pitch, 0.024" (0.61mm) height above board, and gold contact finish with the 24-position BM20B(0.6)-24DS-0.4V(51) and the 20-position BM20B(0.6)-20DS-0.4V(53). Pick the count that matches your BOM circuit requirement; the mating half and stacking height remain consistent across the series.
