Wireless KNX-Ready Energy Harvesting Switch

CHERRY presents new energy harvesting KNX-RF wireless switch module

CHERRY Industrial Solutions presents an energy harvesting wireless switch module for KNX-RF at Light+Building 2014 in Frankfurt from 30th March until 4th April in Hall 9.0 at Stand A66. In recent years the KNX-standard has developed from a cable-based twisted-pair approach and radio technology to a fully integrated radio technology with ETS configuration. The wireless switch module now even adds the energy harvesting aspect.

The ready-to-assemble KNX-RF wireless switch module from CHERRY can directly be integrated into switches with customized control units or design-parts and requires no wires or batteries. It is designed for all switch series with a standard inner frame of 55x55mm. The actuation of the switching unit produces enough electrical energy to transmit a complete KNX-RF ready protocol in S-mode directly to any KNX-receiver. There is no need for a gateway and the configuration is done via ETS as standard. The transmitter has a range of 30m in the 868 MHz band. The radio electronics can also be used in the 915 MHz band.

The maintenance-free module has been optimized for a low actuation force and a low operation noise. Variants with a double rocker and two channels including a complete dimming function are currently being developed.

On 30th March 2014 at 4.15pm, Arno Erzberger, Product Manager for energy harvesting wireless switch products at CHERRY, is giving a paper about ‘Energy harvesting as fully integrated part of building automation’ at the Technology Forum of ZVEI and Messe Frankfurt at Light+Building 2014 in Hall 8.0 at Stand C41.
