Design and mode of operation

Our industrial switchgear are based on the innovative EnOcean radio technology. The energy required for the radio technology is generated from the process or ambient energy. Examples for this freely available process energy are switching processes, light, vibrations or even temperature differences. Through this method switchgear can be operated without batteries – they are self-sustaining and aretherefore wireless and maintenance-free.

steute offers radio industrial switchgear for the most various aplications. The radio switches draw their energy from a powerful, miniaturised solar cell. Inside the compact EnOcean radio module integrated in the switch there is also a tiny energy supply which secures the autarkic function during day/night cycles or shift operation in artificiallighting up to 2 days in darkness.

The signal transmission is carried out on the licence-free SRD band (Short Range Devices) at 868 MHz at 10 mW transmission power. On actuation of the switchgear a very short telegram is spontaneously sent out that contains an individual 32 bit identification number and the usable information. A safety protocol and multitransmission of this information guarantees highest transmission safety. As an additional safety feature a periodic presence signal is sent in order to recognise interferences in the system early enough.

The radio signals are processed by receiver units with integrated EnOcean radio technology. Assessment of the switching information is carried out in the compatible receiver solution. Therefore specific industrial receiver solutions with digital outputs for direct signal evaluation, as well as EnOcean receiver terminals for industrial control units, e.g. the WAGO-System 750 are available.

We develop specific switchgear concepts that use other energy sources for the design of maintenance-free radio solutions. For example the energy drawn from the actuation of the switch itself. For special cases long-lived batteries that have stand-by times of up to 10 years can also be used. Discuss your requirement profile with us.

Optimise processes

This goal is playing an increasingly important role in the definition and design of industrial systems and machines. Radio technology offers many advantages: flexibility of installation, information about moving and rotating parts, reduction in installation and standstill times, sensor technology directly in the manufacturing process, early fault detection by integrated radio sensors. Maintenance-free radio sensors allow for many different applications and are revolutionising the processing sector.

Increase process quality

For example with radio position switches that are applied where moving parts on machines and systems must be positioned, controlled and monitored.

Reduce process times

For example with pull-wire switches that are mounted in the right place in no time at all and are applied to start machines or to open and close electrically-operated doors, gates and fences.

Optimise process costs

For example with wireless door handle switches that are applied for the unlocking of solenoid interlocks on guards and doors.
