  1. Mobile control systems
  2. Radar sensor for collision avoidance

Robust and reliable radar sensor for collision avoidance

Advanced radar technology enables reliable object detection under harsh environmental conditions. Frequency modulated continuous wave radar technology combined with doppler effect enables the sensor to detect distance, position, speed, and the direction of movements of multiple objects.

The robustness of radar technology, the wide range of operating temperature, and the high protection rating makes them perfect for outdoor applications.

Distance Position Direction Speed


Obstacle detection and collision avoidance
Detects obstacles around the moving mobile equipment before a collision happens.
Displays the process values of the nearest obstacles and alerts the driver in real time.
Supports the drivers in monitoring blind spots.
Position detection of vehicles
Ignores fog, steam, and smoke that "blinds" most vision-based technology.
Detects vehicle in a car wash reliably before automatic washing starts.
Load height and speed detection
Simultaneously detects belt speed and conveyor load height without contact.
Users can calculate volume of the loads with this information.
Distance and height monitoring
Detects the ground and measures the height of crops reliably.
Impervious to dust that is challenging for vision-based technology and wind that adversely affects ultrasonic technology.

Collision avoidance in airports -- Belt-loader use case

Millions of people fly each day and airports must be efficient and safe. A reliable collision avoidance system ensure safe operation during loading and unloading of cargo.

Radar sensors detect the parked airplane as the belt-loader approaches. It signals the machine to slow down when it enters a danger zone and stops the machine at a predetermined distance.

The operator then has control, using other sensing technologies, to move the belt-loader the final few inches and land the belt safely in the cargo.

Radar sensor uses wide angle field of view (in red) to detect the plane as the belt-loader approaches

System overview

The radar sensors can be connected in an architecture using ioControl I/O modules or IO-Link masters as desired.

Connection architecture for motor control with HMI controller, I/O, and CAN connections.

ioContol I/O modules are available with DEUTSCH connectors or M12 A-coded connectors

IO-Link communicates to the controller via Ethernet and uses standard M12 patchcords for sensor connection
