Radar sensors

Your Benefits

  • The resistant collision avoidance system and driver assistance made to work in a diverse range of applications under any weather conditions
  • A configurable sensor even makes it possible to detect awkward objects in extreme situations
  • Large sensing ranges and detection beams are ideal for detecting objects early to provide reliable collision avoidance even under high workloads
  • Quick and cost-effective adaptation to local conditions
  • Long maintenance cycles to provide high levels of availability
  • No additional wiring is required thanks to high level of independence from interference signals


The RAS4xx product family is made up of radar-based sensors for collision avoidance with a high sensing range and a large detection beam. They are suitable for applications in ports, large cranes, or large devices in the mining and construction machinery sectors. And when it comes to detecting potential collisions and outputting the appropriate signals, they are reliable in any weather conditions.

At a glance
  • Optional and simple sensing range adjustment of up to 20 m
  • High level of availability even with contamination and in poor weather conditions
  • Simple mounting and adjustment
  • Additional sender / receiver modules
