Radar sensors for object detection and collision avoidance

Collision avoidance systems are not only found in cars in the form of distance warning systems, lane change and emergency braking assistants. Trucks, tractors, construction vehicles, cranes, robots and drones are also dependent on reliable collision warning sensors in order to avoid damage and accidents caused by collisions with people or obstacles. Weather-independent radar technology is particularly suitable for collision protection.

Weather-independent radar technology is particularly suitable for collision protection.

Radar sensors for collision protection detect obstacles by
obstacle detection by measuring the position of static or moving objects in the radar beam. If the radar sensor detects an obstacle within defined distance values, a multi-stage safety process can be activated. Trucks, tractors, construction vehicles, cranes, robots and drones depend on reliable sensors for collision warning to prevent damage and accidents caused by collisions with people or obstacles. Weather-independent radar technology is particularly suitable for collision protection in outdoor applications.

  • analog output 4 ... 20 mA + 3 switching outputs

Maximum signal strength

Mounting bracket for optimum alignment of the sensor to the application

Precise alignment of the sensor to the measurement object is crucial for optimum measurement results. The maximum signal strength of the reflected radar wave is achieved by aligning the radar sensor at right angles to the surface of the measurement object. Especially with a narrow aperture angle, the tolerances for a deviation from the vertical are relatively small in order to receive a signal at all.

For quick and precise alignment, corresponding mounting brackets are available for the RAD5xx series.
RAD5xx series, either for rotation about one or two axes perpendicular to the measuring direction.

Angle reflector for optimizing the signal strength in the application

Uneven surfaces or problematic focusing on a target object at a greater distance can strongly influence the signal strength of the radar signal to be received. Angle reflectors can help to increase the signal strength for greater measurement accuracy.

  • Increasing the signal strength received from a target.
  • Increasing the possible angle between the sensor
    and the target.

Angle reflectors "bundle" the radar signals over a larger area. The geometry is designed so that reflections at any point (b+c) travel the same distance to and from the sensor as the direct reflection (a) at a 90° angle.

Maximum transparency

ConfigBox for easy visualization of the echo curve as well as
Setting the parameters and filter functions

For transferring the sensor data to a PC/laptop. After connecting the sensor to the PC via the ConfigBox, the configuration software is opened via the browser.

The software can be used to configure the sensor to the respective
application requirements or to check its status during operation. In addition to the visualization of the echo curve, the following settings can be configured:

  • Configuration of the analog interface
  • Setting the switching points for the switching outputs
  • Setting the measuring range
  • Definition of the signal threshold value
  • Selection of the desired signal for multiple peaks
  • and much more.
