Robust ultrasonic sensors – U500 and UR18

The next generation of ultrasonic sensors excels with reliability in any situation due to the integrated setting and filter options via IO-Link interface. The unique combination of the narrowest blind range on the market combined with the large sensing range provides new freedom in machine construction by simplified design-in.

The U500 and UR 18 ultrasonic sensors are more robust than ever and highly cost-efficient. Due to a hermetically sealed sensor element with an extremely robust PEEK foil, the ultrasonic sensor becomes considerably more robust.

Thanks to the OneBox design, they are identical in design and size to their optoelectronic pendant, offering the user maximum flexibility in the planning phase or for later retrofitting measures.

The integrated settings and filters allow the ultrasonic sensors to be optimally adjusted to the application. This not only reduces the variant diversity but also ensures an even more reliable solution. The video shows the following examples:

• The flexibly adjustable sound cone for a stable measurement
• The reliable double sheet detector
• The interrupt filter using the example of a clock unit

• Synchronization function for simultaneous monitoring of filling levels at high process speed
• Multiplex function enables maximum process safety by preventing mutual interference

• Detection of one, two, or more layers of materials such as foil, paper, cardboard, labels, or even thin metal sheets
• In addition to double sheet testing, typical applications are film tear detection, bonding surface detection, and label inspection

• Detection of a great variety of materials with different geometries
• Flexible sonic cone adjustment for optimal sensor setting to the application

• Fastest object detection due to barrier principle independent of the shape and nature of the objects
• Due to the hermetically sealed sensor element, the sensor is chemically and mechanically robust and can withstand even intensive cleaning processes

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

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
