sWave® 2.4 GHz-safe

A new system with essential advantages

In order to offer a reliable, manageable and practicable wireless technology steute has developed especially for safety-related industrial application the wireless system »sWave® 2.4 GHz-safe«

On the basis of years of experience with different wireless technologies, a new system has been designed with essential advantages:

  • low energy consumption
  • fast link connection
  • low costs
  • long battery life

All requirements regarding robust and safe application in an industrial environment are met.

The new wireless standard has been especially designed for the requirements of machine and plant engineering. It meets high safety standards: The TÜV evaluation according to ISO EN 13849-1 Performance Level PL d or according to IEC 62061 SIL 2. The signal transmission is reliable even under unfavourable environmental conditions.

High interference resistance

sWave® 2.4 GHz-safe has been optimised for a sensing range of 15 m under consideration of perturbation that is evident in a production site. Safety-related signals are transmitted wireless without disturbing cables. The values can be depending on the environmental conditions go below or beyond target.

sWave® 2.4 GHz

Application field wireless technology

Wireless foot switches have many advantages in machine and plant engineering, for different reasons. On the one hand, cables are dangerous tripping hazards; on the other hand, cables restrict ergonomic comfort because the operator cannot position the foot switch freely in front of the machine. This technology, operating on the license-free 2.4 Ghz frequency band, offers high reliability and robustness.

Wireless Coexistence

Most of the wireless technologies in use today operate on the 2.4 GHz frequency band. Devices using these wireless technologies have become an integral part of the existing infrastructure in offices and production lines. In cases where WLAN, IEEE 802.15.4 (ZigBee) and sWave® 2.4 must be operated in parallel, the 2.4 GHz frequency band is working to full capacity. Through a special procedure a coexistence with sWave® and other technologies is secured to the greatest possible extent.

sWave® 868 / 915-e MHz self-sufficient, bi-directional

Wherever movable parts of machines and plants need to be positioned, controlled and monitored, cables are undesirable or a hinderance, reducing the viability of the plants. The solution: wireless, self-sufficient command devices which are applied to authorise solenoid interlocks on safety fences and protective guards. Wireless position switches which position, control and monitor machines and plants.

sWave® 868 / 915-b MHz battery-operated, bi-directional

Application field wireless technology
Industrial sensors, for example wireless inductive sensors, GMR sensors or optical wireless sensors, require additional energy for operation. These sensors draw their energy from a powerful longlife battery integrated in the sensors (e.g. position switches, operating devices, non-contact wireless sensors).

Special features

  • Bi-directional self-sufficient wireless path
  • High sensing range: up to 60 m inside buildings and 700 m in free field
  • No interference with DECT, WLAN, PMR systems, etc.
  • Good integration in automation systems
  • Short telegrams (small duty cycle) lead to low collision probability
  • Also possible with battery operation
  • Non-contact wireless sensors possible

EnOcean

The EnOcean wireless technology has already been established as a technology for green, intelligent buildings and applications. Wherever an interoperability with the EnOcean standard ISO/IEC 14543-3-10 is required for industrial applications, this standard is integrated in our wireless switchgear and sensors. It has been optimised for uni-directional wireless systems, based on an energy harvesting system.
