UF

• The clear choice for detecting transparent labels
  
• The UF ultrasonic sensors reliably detects labels and materials,
  regardless of printed design, transparency or surface characteristics. Unlike
  optical sensors, the UF3 relies on damping – a process where the thickness of
  a material determines the degree to which the sensor absorbs sound waves.
  
• A high level of positioning accuracy and stable response times make the
  fork sensor suitable for nearly any environment.
  
• Due to its small, compact metal housing, the UF can be used in harsh
  conditions and where space is limited.
  
• As a result, the UF3 can distinguish between labels located just 2 mm
  apart from one another on an adhesive tape.
  
• Applications include detecting transparent labels on transparent
  substrates, detecting labels with different printed designs or differentiating
  between single- and two-ply materials.
