Radar sensors


The radar sensors of the QT50 and Q120 series can be used under almost all environmental and climatic conditions. They use FMCW technology (Frequency Modulated Continuous Wave) to detect stationary and moving objects, such as cranes, cars, trains, trucks and cargo.

Radar barrier for easiest object detection

Measuring distances from 0 to 8.5 m
Fast response time (5 ms)
Ideal for object with irregular surfaces

The radar sensor is also available in a configuration, where it operates similar to a light barrier. Via a special teach-in-algorithm the sensor learns the reflector position. After teaching the sensor monitors the reflector position. If an object breaks the line of sight between the sensor and reflector, the sensor output switches. The advantage of this configuration is that it is unnecessary for the object to reflect a signal back to the sensor. Therefore even randomly-shaped objects or radar absorbing objects can be reliably detected.

Distance measurement through a cover

This model measuring distances to 8.5 m
Continuous measurement signal plus discrete switching signal
Voltage, pushpull
Ideal for objects covered or protected by a semi-transparent material

Distance measurement to flat or round objects

RR30 series
Can be used outdoors and in a wide temperature range of -40 to 65 °C / -40 to 150°F without additional protective housing. The sensor withstands stress tests such as IP68 / IP69K test and the even more demanding proTect+ without any problems

Wide Beam (90° x 76°) Collision Avoidance Radar Sensor

High sensitivity radar-based sensors ideal for collision avoidance on board mobile equipment, like reach stackers, forklifts, and mining vehicles.

Fourth generation FMCW (true-presence) radar detects moving and stationary objects
Higher sensitivity and longer range
Adjustable sensing field — ignores objects beyond setpoint
Easy setup and configuration of range, sensitivity, and output with simple DIP switches
Sensing functions are unaffected by wind, falling rain or snow, fog, humidity, air temperatures, or light
Sensor operates in Industrial, Scientific, and Medical (ISM) telecommunication band no special license required
Rugged IP67 housing withstands harsh environments
