This socket mates with the BM24-40DP/2-0.35V(53) header, which carries outer shroud contacts and a 0.026\" (0.65mm) height. The combined mated stack height is 0.8mm — the header sits lower, and the socket's 0.031\" (0.80mm) profile sets the total z-height between boards. The 0.35mm pitch means the header and socket must align within a tight tolerance during board assembly; the solder retention pads on both halves help keep the parts registered through reflow.","metaTitle":"Hirose BM24-40DS/2-0.35V(53) Socket, 0.35mm Pitch, 42 Pos","metaDescription":"Hirose BM24 series socket, 42 positions (40 signal + 2 power), 0.35mm pitch, 0.80mm mated height.
