energy harvesting wireless switch for industrial applications from CHERRY

Easy connection with standard SPS bus system like OpenCAN and Profibus

Auerbach / OPf, Germany, 26th November 2013 – At SPS IPC Drives 2013 in Nuremberg from 26th to 28th November in Hall 7A on Stand 604 CHERRY Industrial Solutions shows its energy harvesting wireless switch for industrial applications as a batteryless alternative for wired micro-switches.

With the progressive intelligent networking in the industry and the trend for the ‘intelligent factory’ the energy harvesting switch from CHERRY offers many advantages in applications where a complex wire assembly would be disproportionate to the actual application. The required RF-energy is created by the mechanical actuation of the switch and the data is transmitted wireless via RF-technology. Because of this there is no need for expensive and complex connection systems and no wear of any cable-connection. Thanks to its compact design the wireless switch is very easy to install – even in hard-to-reach places.

The energy harvesting wireless switch for industrial applications is available in two package versions: as a rocker switch (monostable and bi-stable) for actuation by hand and as a snap-action switch for mechanical actuation, e.g. by a machine. The switch can easily be connected with a standard SPS bus system like OpenCAN and Profibus. The signal received by the receiver is simply transmitted to a SPS.

CHERRY’s energy harvesting wireless switch offers a high energy yield of 2x min. 0,33mWs (monostable) and 1x min 0,33mWs (bi-stable), an operating temperature range of -40 up to +85 degrees Celsius, and a long mechanical life of up to 1.000.000 operations. The operating force is 8N (monostable) and 3N (bi-stable). The vibration resistance is 5g and the shock resistance is 15g. Furthermore the switch is fully network-compatible.

Several available radio frequencies (e.g. 868 MHz and 915 MHz (with a radio range of 30m) and 2.4 GHz (with a radio range of 10m)) enable worldwide use in numerous applications. A flexible pairing allows for operation of several receivers with one switch (and vice versa). A ‘unique ID’ excludes a mutual interference between different RF-switches. As there is no need to change or dispose any batteries, the switch is very environmentally friendly and maintenance-free.

Serial production for the two package versions with receiver for industrial applications was launched at the end of July 2014.
