0.35mm Pitch Header with Dedicated Power Pair
The Hirose BM24-10DP/2-0.35V(53) is a 12-position header from the BM24 series, configured as 10 signal contacts plus 2 dedicated power contacts in a dual-row layout. The mated stacking height of 0.026" (0.65mm) defines the z-axis clearance between parallel boards in a mezzanine stack.
The 12 total positions break down as 10 signal lines and 2 power contacts. This is not a 12-signal connector — if your circuit count is 12 signal lines, the BM24-20DP/2-0.35V(53) with 20 signal + 2 power (22 total) is the next step up in the same series. The BM24-10DS/2-0.35V(53) is the mating receptacle, a socket with center strip contacts at the same 0.35mm pitch and a slightly taller 0.031" (0.80mm) stack height — confirm the z-height budget before pairing them.
