More features & usability.

Our radar sensor offers the highest precision and speed, a wide measurement range – and much more.

Maximum precision

The OndoSense apex radar distance sensor offers a measurement accuracy in the micrometer range: Benefit from a unique measurement precision of up to ±1 µm with a linearity error of only ±300 µm!

High measuring rate

In some applications, the measurement speed can be decisive: With our OndoSense apex radar distance sensor, you will benefit from the highest measurement rate with up to 300 Hz.

Very narrow opening angle

With an opening angle of only ±2 °, which is very narrow for radar sensors, our distance sensor enables focused and reliable measurements with minimal interference.

Established interfaces

Benefit from high-performance industrial interfaces for data transmission: analog current loop (4–20 mA), digital switching outputs (3x push-pull), serial (RS485) and Profinet (via gateway).

Wide measuring range

Our distance radar sensor is great for close-range measurements. In addition, the OndoSense apex offers a wide measuring range from 0.1 m to 6 m (long range version: 0.3 m to 40 m).

Attractive & practical UI

Our browser-based configuration software offers a user-friendly GUI with many practical features e. g. the "Peak Finder", which lets you select the peak that corresponds to your target object very easily.

More applications & challenges.

Our smart distance radar sensor supports numerous applications in a wide range of industries.

Distance measurement & complex dimensioning

  • Simple distance measurements to objects, even through packaging
  • Complex dimensional measuring of objects – e. g. width, length, height, profile etc.
  • Measurement of tolerances and deviations

Presence control & detection of concealed objects

  • Non-destructive, non-optical presence control of concealed components
  • Detection or positioning of objects in or behind plastics, cardboard, packaging or other non-conductive materials

Positioning of machines or objects

  • Precise positioning of machines in one or more dimensions
  • Determination of the position and size of objects
  • Detection of obstacles for basic collision avoidance

Continuous monitoring & profiling

  • Level monitoring of liquids and solids in difficult environments (e. g. dirt, dust, steam, etc.) at close range and in narrow spaces
  • Creation of surface profiles – even with rough materials
  • Measurement of flatness or edge camber – e. g. for metal sheets or plates

Condition or status control via switching outputs

  • Configuration of 3 push-pull outputs for the classification and detection of objects
  • 2 control modes: single point (1 switching point) & window function (2 switching points)
  • Optimized output stability through hysteresis – e.g. in case of unsteady distance measurements in the vicinity of the switching point

More robustness & reliability.

Our radar technology is insensitive to dust, smoke, fog, rain or adverse light.

The OndoSense apex radar distance sensor stands for highly precise and reliable measurement results – even with dirt, smoke, steam, rain, snow, poor lighting conditions, flashes of light or rough surfaces. With its dust-tight, jet-proof housing (IP 67) and its resistant PTFE lens, our robust distance radar is the ideal choice for challenging production environments.

You would like to use our radar sensor for distance measurements in extreme conditions – e. g. in the metal industry? No problem! Our optional heavy-duty housing offers maximum protection via a connection for water cooling. This enables reliable measurement results even in the harshest settings.
