Radar sensor for object recognition and collision avoidance
The compact RAD51C radar sensor is suitable for the tightest installation situations and the harshest environmental conditions.With an opening angle of ±8° (16°), the sensor offers maximum reliability for object detection.
Thanks to a measuring rate of 100 Hz and measuring ranges between 0.15 m ... 20 m or 0.3 ... 30 m, countless applications can be realized with the latest radar technology. Simple tools not only help with implementation, but also create transparency during operation.

Wide measuring range
- Measuring range 0.15 m to 20 m or 0.30 m to 30 m
- Small blind area of only 0.15 or 0.3 m
- Measurement rate up to 100 Hz
- Repeatability up to ±2 mm
- Wide opening angle ±8° (16°) for reliable object 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.
- For flexible and reliable monitoring of safety areas, up to 4 sensor zones can be set via the switching outputs
- 92,65 mm total length incl. M12 connector
- Standardized mounting due to M30 mounting thread
- Matching mounting accessories for easy mounting and alignment on the application
- Latest radar technology for reliable measurement even under the most adverse environmental conditions such as dust, fog, rain, smoke, wind or unfavorable light conditions.
- 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.
