BM24-24DS/2-0.35V(53): High-Density Board-to-Board Socket
The Hirose BM24-24DS/2-0.35V(53) is a 26-position socket with center strip contacts, part of the BM24 series. It carries 24 signal contacts plus a dedicated 2-power pair, all on a 0.014" (0.35mm) pitch in a dual-row layout. The 0.031" (0.80mm) height above board sets a fixed mated stack height of 0.8mm, making it a tight board-to-board mezzanine interconnect for compact handheld or portable electronics where z-height is at a premium.
Position Count and Power Pair
The 26-position count breaks out as 24 signal circuits plus 2 power contacts. Compared to the BM24-20DS/2-0.35V(53) (22 positions: 20 + 2 power), this part adds 4 signal lines at the same 0.35mm pitch and 0.8mm stack height. The 2 power contacts are dedicated — they are not shared with signal lines, so the board layout can route a local supply rail through the connector without stealing a signal pin.
Surface Mount and Solder Retention
The 0.35mm pitch means the PCB footprint must be tight — expect fine-pitch routing and via-in-pad if the signal count is high.
