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. For example 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.

• 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
