Hirose Electric has developed the FH76 Series, a One Action FPC connector that features the world’s lowest profile (0.5 mm) and narrowest pitch (0.175 mm) among connectors with a One Action structure. Optimized for compact and ultra-thin devices like smartwatches and foldable smartphones, the FH76 Series uses a simple One Action locking mechanism that eliminates the need to operate an actuator during FPC insertion—reducing the risk of assembly errors. This connector helps address the design challenges of increasingly thin and functional wearable devices.
Example of Expected Application
Smartwatches, wearable devices, smartphones, and other compact electronics
Contributing to the advancement of the consumer market through further miniaturization, device thinning, and improved usability.
In compact wearable devices like smartwatches and smartphones, the demand for ultra-low-profile, space-saving connectors continues to grow—driven by thinner designs, more integrated functions, and larger batteries. For smartphones in particular, reducing thickness on one side is key, making low-profile connectors indispensable. However, as connectors become thinner, operating traditional actuators becomes more difficult, slowing down assembly and increasing the risk of error. This has led to growing interest in One Action connectors that simplify the process by eliminating the need to operate the actuator.
To address these demands, Hirose Electric developed the FH76 Series—an ultra-low-profile FPC connector that features the world’s lowest profile (0.5 mm) and narrowest pitch (0.175 mm) among One Action connectors. Its streamlined locking mechanism eliminates the need to operate the actuator during FPC insertion. Even after mounting, the actuator stays securely closed during transport, reducing the risk of detachment or damage. The One Action design also supports automated assembly, helping manufacturers improve efficiency and reduce human error.
