Reliable detection of objects with critical surfaces and highly transparent objects

Ultrasonic sensors

Highlights

  • Reliable detection of objects with critical surfaces and highly transparent objects
  • Available in cubic (32 x 20 x 12 mm) or barrel type (M12/M18/M30) housing options
  • Simple adjustment via teach-in, control input or display

As a result of its narrow sound cone, UT-20-S allows the detection of objects even through the smallest of openings and drilled holes with a diameter of less than 5 mm.

Typical Ultrasonic sensors

Ultrasonic sensors may be a useful alternative where optical sensors come up against their physical limits. This applies, for example, for objects with uneven surfaces or under difficult ambient conditions, or with highly transparent media as well as moving, highly reflective liquid surfaces.

Typical uses of ultrasonic sensors are therefore checking the presence of highly transparent foils and measuring the filling levels in liquid containers. A major advantage of ultrasonic sensors is the absolutely reliable background suppression resulting from their sound time-of-flight measurement principle.
