Area of application

  • Obstacle Detection (Detection of objects locked in between LX-barriers)
  • Vehicle detection (outside danger area) for optimized traffic flow on Level crossings in combination with traffic
    light signals
  • Traffic surveillance

  • SIL 3 fail-safe system according to CENELEC resulting from its multi-redundant design
  • Permanent detection of moving and non-moving objects in the entire surveillance area
  • Up to 4 different zones of interest (danger zones) can be configured and evaluated independently
  • Fail-safe operation based on continuous self-testing
  • Several track crossings within the reach of the sensor can be covered by one system, for example additional
  • Preventive maintenance free over the entire lifetime.
  • Not influenced by day to day and seasonal variations
  • Not influences by weather conditions such as rain, fog, snow, ice, etc.
  • For complicated crossing sites, several sensors (up to 8) can be combined to cover the entire LX.
  • No interference with other electronic systems
  • Operates in the free 76-77 GHz Band.


The flex ray system is based on the newest radar technology and has been especially designed for the purpose
of detecting and analyzing road traffic (vehicles and pedestrians).
The technology has proven its capability and reliability in a thousandfold traffic control applications worldwide.

This system takes advantage of state of the art radar technology in combination with the large frequency bandwidth of 1 GHz. This provides very high accuracy and guarantees reliability of the detection.
