Image of Hirose BK11 Series FPC-to-Board Connectors The Hirose BK11 is an ultra-compact FPC-to-board connector engineered for power and performance in portable electronics. With a 0.35 mm pitch, 0.6 mm stacking height, and slim 1.9 mm width, the BK11 delivers up to 8 A total current through a multi-power hybrid layout featuring two main power contacts (4 A) and four sub power contacts (2.5 A). This structure supports power delivery to multiple modules through a single connector, reducing component count and saving mounting space. Armored metal guides, reinforced solder points, and a tactile click design ensure secure, reliable mating even in compact or vibration-prone devices. Ideal for smartphones, wearables, wireless audio, and other battery-powered products, the BK11 Series offers a robust and space-saving connectivity solution.
