Your benefits
  • Designed for extreme environments
    • Can be used outdoors and in a wide temperature range, from -40 to 70 °C, without additional protective housings. The sensor withstands stress tests such as the IP68 / IP69K test and the even more demanding proTect+ without any problems
  • Stable measuring signal, even with adverse ambient conditions, ambient light, and dirt
    • Good repeatability < 1 mm and limited temperature drift < ± 10 mm
  • Low total cost of ownership due to its very rugged design
    • Maximum chemical resistance due to the wear resistant housing (stainless steel body with Ecolab certificate and thermoplastic polyetherimide (PEI) front surface or off-highway-compatible plastic housing)
  • Simple and versatile installation
    • The radar sensor is available in a very small design, making it suitable for very confined installation spaces
  • Quick measurements and reaction to position changes
    • Extremely short reaction times < 5 ms
  • Distance measurements in a narrow cone across long distances
    • Focused, very narrow radar beam with a measurement range of up to 40 m

Technology
Distance measurement to flat or round objects

Distance measurement to flat or round objects

For flat objects it is very important that the tilt of the surface is not greater than half the opening angle. This is to ensure that radar beams reflected from the surface are reflected back into the sensor for proper detection. Round objects have the advantage that they are rotationally symmetric. This makes alignment much easier, as round objects always reflect something back to the sensor. Compared to a flat object with comparable size, the signal strength of the reflected  beam is reduced.

Radar beams can penetrate certain materials (such as plastic panes). The covers do not require full transparency to be penetrated by radar beams. For example it is possible to look through black plastic sheets. A small portion of the radar beam will be reflected back to the sensor from the cover. Through a special teach-in-algorithm the sensor learns the profile of the reflection. It subsequently measures objects behind the cover, as if the cover is none-existent.

Radar barrier for the most reliable object detection

Radar barrier for the most reliable object detection

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.
