The 0.014\" (0.35mm) pitch and 0.024\" (0.61mm) height above board make it one of the lowest-profile mezzanine connectors available, suited for compact handheld and wearable electronics where every tenth of a millimeter matters. Two of the four positions are dedicated power contacts, allowing a mixed signal-and-power interconnect in a single connector body. ## Pitch and Stack Height Drive the Board Layout The 0.35mm pitch demands a fine-line PCB footprint — expect trace widths and spaces in the 0.15mm to 0.18mm range for breakout. The 0.6mm mated stack height means the two PCBs sit nearly flush; this connector is for applications where the total z-height budget is under 1mm. The gold contact finish on both mating surfaces ensures reliable electrical contact through repeated mating cycles in low-voltage digital circuits.","metaTitle":"Hirose BM29B0.6-2DS/2-0.35V(53), 0.35mm Pitch","metaDescription":"Hirose BM29 series receptacle, 4 positions (2+2 power), 0.014\" (0.35mm) pitch, 0.6mm stacking height, gold contacts, SMT.
