Video "Robust ultrasonic sensors U500 / UR18"
How robust are the new U500 and UR18 ultrasonic sensors?

The new U500 and UR18 ultrasonic sensors from Baumer are more robust than ever and highly cost-efficient. This is achieved by a PEEK foil, which protects the sensor element and is hermetically sealed by laser welding. The cubic U500 is identical in design and size to its optoelectronic pendant O500, offering the user a high degree of flexibility in the planning phase or for later retrofitting measures.

What can this sensor survive? How about sandblasting? Find out in this video.

Your benefits
  • Highest process reliability and longevity
    • Uniquely robust and resistant sensor thanks to hermetically sealed sensor element with PEEK foil
  • Flexible and application-specific parameterization
    • Various setting options, such as sonic beam width or filter functions, with IO-Link
  • Measurement almost to the sensor surface
    • Extremely short blind range of 20 mm with a range of up to 1000 mm
  • Consistent operation thanks to interference resistance
    • Detection of transparent, high-gloss and multi-color objects with maximum resistance to soiling, water drops or chemical substances such as rinsing and antifreeze agents or isopropyl alcohol
  • Simple and fast commissioning
    • Adjustment of sensor characteristics directly at the sensor via qTeach as well as centrally via IO-Link
  • Industrie 4.0 and IIoT ready
    • Standardized communication interface IO-Link
  • Freedom in plant planning
    • Identical functions and various mounting options in cubic and cylindrical design as well as identical dimensions of the U500 and the optical counterpart O500
  • Hybrid operation - analysis of additional process data parallel to operation
    • Read out process data, e.g. number of parts or temperature values, while the machine is controlled via the switching output

  • Detection of full or empty bottles in the splash zone
  • Detection of pallets with foil packaging thanks to long range
  • Level detection/vibratory feeder monitoring during material feed
  • Detection of wooden trunks in very dusty environments
  • End detection at metal strips with plastic content with only one sensor thanks to wide sensing range
  • Position monitoring of big bag packages in bulk packaging
  • Optimum foil detection thanks to easy, flexible configuration via IO-Link or qTeach
