Packaging industry

High standards for process safety combined with maximum flexibility for the detection of various packaging materials and shapes

  • Increase plant availability and master variant diversity: Ultrasonic sensors detect objects regardless of material, color, transparency, and gloss, as well as surface properties. The parameter server function and fast parameterization via the IO-Link interface allow simple and fast format changes.
  • Save development time and costs: Fast design-in of the ultrasonic sensors thanks to a very short blind region with a long range, small design, and standard hole spacing.

Electronics industry

Differently perforated and glossy surfaces with narrow space requirements for sensors

  • Save development time and costs: Fast design-in of the ultrasonic sensors thanks to a very short blind region with a long range, small design, and standard hole spacing.
  • Maximize plant availability: Ultrasonic sensors detect objects regardless of material, color, transparency, and gloss, as well as surface properties.
  • Increase throughput: Short response times and high repeatability enable maximum throughput.

Feeding technology

Wide variety of object geometries and surfaces with narrow space requirements for sensors

  • Highest process safety: Safe object detection independent of the object. Not affected by dust, light, or moisture.
  • Save development time and costs: Thanks to integrated adjustment and filter options, various application requirements can be optimally met with one sensor type. This reduces the variety of sensors and thus warehousing costs.

Reliably high-performance ultrasonic sensors with integrated setting and filter options
 

The new generation of the ultrasonic sensors U300, U500 and UR18 impresses with reliable integrated setting and filter options via the IO-Link interface in every situation. The choice of the preset sonic cone width (narrow, medium, wide) allows individual adjustment to the format. This means that different application options can be reliably handled by a single sensor, reducing variant diversity. Watch the video to find out more about the setting and filter options and how you can benefit from them. What is more, the unique combination of the shortest blind region on the market and extensive range offers new opportunities for machine construction and simplifies the design process.

Technology

Ultrasonic sensors are based on the measured propagation time of the ultrasonic signal. They emit high-frequency sound waves which reflect on an object. The objects to be detected may be solid, liquid, granular or in powder form.  Ultrasonic sensors reliably detect transparent and other demanding objects where optical technologies fail.

Ultrasonic proximity switches – Functionality of ultrasonic sensors

Ultrasonic proximity switches

Transmitter and receiver are integrated in one housing. The sensor switches as soon as the sonic signal is reflected back by an object within the adjusted sensing range (background suppression principle).

Advantage: simple installation, low cabling efforts

Ultrasonic retro-reflective sensors

Ultrasonic retro-reflective sensors

Transmitter and receiver are integrated in the same housing. The sensor detects the sound reflected by a fixed reflector. The sensor switches as an object interrupts the distance between sensor and reflector.

Advantage: Independent of object attributes, reliable signal even with extremely weak or diffuse reflective or sound-absorbing objects

Ultrasonic through beam sensors

Ultrasonic through beam sensors

Transmitter and receiver are mounted opposite each other in two housings. The sensor switches as soon as an object interrupts the sound waves.

Advantage: shortest response times of all ultrasonic sensor principles, longer ranges than in the size comparable retro-reflective sensors or proximity switches
