  • Safe: Safety Integrity Level (SIL) 4, based on CENELEC EN 50129

  • Flexible: Observes a parallelogram shaped area with configurable angles and size

  • Modular: up to 4 radar sensors can be used in the same installation site covering all geometries of level crossing

  • Performance: Extremely low false alarm probability even in harsh weather conditions (fog, rain, snow) and in all light conditions

  • Reliable: MTBF > 10 years

  • Diagnostic Video Camera: Video (closed circuit TV) transmission when obstacle detection occurs for system diagnostic purposes



The basic configuration is 1 radar and 1 outdoor cabinet.

Radar Sensor:

  • Obstacle detection

  • Communicates with the cabinet through RS485

Corner Reflector:

  • Sensor diagnostic functions


  • Interfaces with signaling through relays

  • Provides power to the radar sensor

  • Records video of the monitored area

  • Transmits information to the remote control system

Remote Control Terminal:

  • Receives all information about the status of the level crossing via LAN or GSM-R .
