It carries a 0.014\" (0.35 mm) pitch and mates to a corresponding receptacle to achieve a mated stacking height of 0.6 mm — one of the thinnest mezzanine interconnect profiles available. The two-row layout splits 2 signal contacts and 2 power contacts, letting a single connector handle both a low-current data line and a small power feed in wearable or handheld devices. Gold plating on the contacts suits repeated mating cycles and low-voltage signal integrity. The 0.35 mm pitch requires a PCB capable of fine-line etching and solder-mask registration. The 0.016\" (0.41 mm) height above board and 0.6 mm mated stack height keep the assembly low. ## Position Count and Power-Signal Split The 4-position count is listed as 2 + 2 Power, with two contacts dedicated to power delivery and two for signal. No end-of-life notice or successor has been recorded.","metaTitle":"Hirose BM29B-2DP/2-0.35V(51) Header, 0.35mm Pitch, 4 Pos","metaDescription":"Hirose BM29B-2DP/2-0.35V(51) header, 0.35mm pitch, 4 positions (2+2 power), 0.6mm stack height, gold contacts, SMD.
