Energy Harvesting Switches from ZF detect status of windows

With an integrated energy harvesting switch, the window handle can provide information on each opening or closing of the window. The mechanical actuation of the RF Switch is created by the change of the window handle status, a small voltage is generated which transmits an RF protocol. This information is used to monitor the status of the window.

The battery free and wireless technology is flexible in-use and can be realised with different RF protocols such as Bluetooth, EnOcean or customer-specific RF protocols. The system can also be used for diverse applications within building automation like lighting, shutters, doors, and windows.

With the help of the ZF products, comfort, safety, and energy efficiency can be increased and improved in a smart way. Energy harvesting switches are a smart, energy-saving solution for the smart home. They work without batteries and are completely maintenance-free.

Versatile and durable in use

Despite its compact size and the high energy output, the generator provides a lifetime of one million switching cycles.

At Light + Building in Frankfurt, 2 – 6 October 2022, ZF will present a window handle demonstration with status monitoring of windows and doors.
