The Hirose BM20B(0.6)-24DS-0.4V(53) is a 24-position receptacle with center strip contacts from the BM20 series, designed for board-to-board mezzanine stacking where the vertical clearance is tight. The 0.016" (0.40mm) pitch packs 24 positions into a dual-row footprint, and the 0.024" (0.61mm) height above board achieves a 0.6mm mated stack height — among the lowest in its class.
The mated stacking height is 0.6mm, with a height above board of 0.024" (0.61mm) for the receptacle alone.
