Wireless and battery-less energy harvesting switches
23 June 2015
CHERRY energy harvesting switch modules are designed to meet the demand for simple and flexible wireless data transmission of switch signals with maintenance-free low energy consumption.
The wireless and battery-less energy harvesting technology is said to offer an alternative to wired or battery-powered solutions. Compatible with multiple wireless protocols and with no need to change or dispose of batteries the solution is flexible, environmentally friendly and maintenance-free.
The key to the range is the energy harvesting generator, which employs a patented mechanism to convert mechanical force into electrical energy in the form of an RF output signal. IP40 protected, offering a lifetime of 1,000,000 switching cycles and an operating temperature range of -40 to + 85°C, versions are available with momentary and latching switch actions and can offer a range of up to 300m in open space.
For communicating with host systems CHERRY offers a ZF proprietary protocol, and is happy to work with customer-specific requirements. To ensure worldwide wireless compatibility the system can be specified to operate at 868 MHz and 915 MHz, or 2.4 GHz for lighting applications.
