Radar sensor for distance measurement and positioning

The compact RAD51D radar sensor is suitable for the tightest installation situations and the harshest environmental conditions.
With a narrow opening angle of ±3° (6°), the sensor offers maximum focusing for positioning tasks.
Thanks to a measuring rate of 100 Hz and measuring ranges between 0.15 m ... 20 m or 0.3 ... 40 m, countless applications can be realized with the latest radar technology. The simplest tools not only help with implementation, but also create transparency in operation.

Wide range of applications
  • Small opening angle ±3° (6°) for precise distance and position detection
  • Different data output options: In addition to the analog output of 4 ... 20 mA, 3 switching outputs are available for a wide range of applications.
Compact and easy to install
  • 92 mm total length incl. M12 connector
  • Standardized mounting due to M30 mounting thread
  • Matching mounting accessories for easy mounting and alignment on the application
Maximum robustness
  • Latest radar technology for reliable measurement even under the most adverse environmental conditions such as dust, fog, rain, smoke, wind or unfavorable light conditions.
Simple commissioning and setting of parameters
  • Connection of the radar sensor to the PC using a configuration box (ConfigBox). Communication via the RS485 interface
  • “See what the sensor sees” through real-time visualization of the echo curve using appropriate software tools. This also enables simple and intuitive commissioning, as the measurement can be tracked live during installation.
  • Numerous setting options, such as setting the measuring range, setting switching points, filters or other features, to customize the sensor system to the respective application requirements.
