OndoSense introduces new distance radar sensor
OndoSense’s new distance radar sensor offers real-time precision up to ±1µm, a 500Hz measurement rate, and easier PLC integration via a Profinet interface.
OndoSense has launched a new distance radar sensor designed for automation in harsh industrial environments.
The sensor features a Profinet interface and a higher measurement rate of 500Hz, providing real-time measurement speed and precision of up to ±1µm.
Additionally, the apex radar sensor can now be integrated into PLC systems more easily than before via the Profinet interface.
The Germany-based company explained that the sensor’s application range includes micrometre-precise distance measurements, complex dimensional measurements, as well as highly accurate level, height, and throughput measurements. It can also determine the position of hidden objects (e.g., behind plastic sheets or packaging).
According to OndoSense, the product has a measuring range of 0.1 to 40m and can be used reliably at both close and long distances.
Moreover, the sensor is suitable for a wide range of industries, including steel, metal, and mining, as well as mechanical engineering, the energy sector, and transport and logistics.
Profinet interface
“With the new Profinet interface for the OndoSense apex, we have reached an important milestone, as customers can now integrate our radar sensor into their PLC systems with ‘plug and play’ simplicity,” explained Mathias Klenner, Co-CEO and founder of OndoSense.
In addition to the Profinet interface, OndoSense also offers variants with an analogue current interface (4-20mA) and digital switching outputs (PNP/NPN).
Optical calibration
The new OndoSense sensor is equipped with an optical calibration aid, visible from all sides, which is attached to the corners of the housing. Four LEDs help easily align the sensor with the target object to achieve the strongest possible radar signal.
“This ensures the radar sensor is quickly ready for use at any time, even for the most challenging measurement tasks, and without requiring specialist knowledge,” OndoSense added. “With a radar lens opening angle of just ±1.5 degrees – remarkably narrow for radar – the sensor delivers stable, reliable measurements with an extremely small measurement spot.”
Harsh environments
The company further noted that the sensor remains reliable even in the presence of dirt, smoke, steam, rain, heat, vibrations, poor lighting, or rough surfaces.
Additionally, with its hexagonal aluminium housing, PTFE lens, and IP67 Protection Class, the radar sensor is well-suited to adverse production environments.
For extreme operating conditions, optional heat shields with air cooling are available, providing additional protection against high temperatures or excessive dirt build-up.
