Switch Energy Harvesting RF Generator

This Energy Harvesting Generator is the rawest form of CHERRY’s technology. When actuated, a mechanical force acts vertically on the end of the generator’s lever. A patented mechanism then converts the mechanical energy generated into electrical energy in the form of an RF signal. Please note that this product must be used in conjunction with suitable RF electronics. The generator is integral to CHERRY’s rocker and snap switches (Rocker – RS P/N 8736671 & Snap – RS P/N 8736675).

Switch Rocker Energy Harvesting RF 868MHz

This wireless momentary rocker switch provides data transfer via RF technology, taking away the need for complex wire assemblies, increasing flexibility for use. The required energy is generated by mechanical actuation of the switch, eliminating the need for batteries. Flexible pairing allows the operation of several switches with one receiver and vice-versa, and the switch “Unique ID” provides clear identification while operating several switches at once. Up to three telegrams are sent per actuation, with pseudo-random timing to assure robust data transmission. This unit works on a frequency of 868 Mhz and uses a proprietary protocol.

Switch Snap Energy Harvesting RF 868MHz

This wireless snap switch provides data transfer via RF technology, eliminating the need for complex wire assemblies, increasing flexibility for use in formerly unreachable locations. The required energy is generated by mechanical actuation of the switch, eliminating the need for batteries. Flexible pairing allows the operation of several switches with one receiver and vice-versa, and the switch's “Unique ID” provides clear identification while operating several switches at once. Up to three telegrams are sent per actuation, with pseudo-random timing to assure robust data transmission. This unit works on a frequency of 868 Mhz and uses a proprietary protocol. A rocker switch version is also available (RS P/N 8736671). A compatible receiver is also available (RS P/N 8736684).

Energy Harvesting Receiver Board 868MHz

This receiver module works with CHERRY Energy Harvesting wireless switches to receive data transfer via RF technology (Rocker – RS P/N 8736671 & Snap – RS P/N 8736675). The system eliminates the need for complex wire assemblies and increases flexibility for use in formerly unreachable locations. Flexible pairing allows the operation of several receivers with one switch and vice-versa, and the “Unique ID” excludes mutual interference between different RF switches.
