The 0.46mm height above the mounting board gives the connector a low profile on the PCB. That is a thin flash — adequate for the limited mating cycles typical of a mezzanine connector that gets mated once at board assembly and stays there. It is not specced for repeated field disconnect cycles; the gold is there to keep contact resistance stable through the solder reflow and the single mate event. The 34-position BM28B0.6-34DP/2-0.35V(51) sits between the 30-position BM28B0.6-30DP/2-0.35V(53) and the 36-position BM28B0.6-36DP/2-0.35V(53) at the same 0.35mm pitch and 0.6mm stacking height. The position count is the only difference — the footprint length scales with the circuit count, so the board layout changes by the number of signal lines needed.","metaTitle":"HIROSE BM28B0.6-34DP/2-0.35V(51) Header, 34 pos","metaDescription":"HIROSE BM28 series header, 34 positions, 0.35mm pitch, 0.6mm stacking height, gold contacts, RoHS.
