The 0.35mm pitch and dual-row layout pack 40 outer shroud contacts into a compact footprint, typical for high-density signal interconnects in mobile devices, wearables, and compact camera modules where z-height is tight. Gold flash plating (1.97µin) on the contacts protects against corrosion in the unmated state, though the thin layer limits the connector to a modest number of mating cycles — typical for a one-time assembly or infrequent field service. ## 40 vs 46 Positions — Same Pitch, Same Stack The BM23 series offers the same 0.35mm pitch and 0.8mm stacking height across position counts. The 40-position BM23PF0.8-40DP-0.35V(51) and the 46-position BM23PF0.8-46DP-0.35V(51) share identical footprint geometry per row — the extra 6 contacts extend the connector length along the board edge.","metaTitle":"Hirose BM23PF0.8-40DP-0.35V(51) Header, 0.35mm Pitch, 40 Pos","metaDescription":"Hirose BM23 series header, 40 positions, 0.35mm pitch, 0.8mm stacking height.
