Ultrasonic Sensors

Ultrasonic sensor solutions for almost any application

Ultrasonic sensors – the allrounders amongst the sensors – always come into use when optical systems reach their limits. Hence, partially and fully transparent or extremely dark objects can be detected just as easily as objects with reflect- ing surfaces or objects in dusty, vaporous or humid environments.

Other advantages at a glance:

  • Mainly surface-independent switching behavior with sound reflecting materials;
  • Excellent background suppression due to propagation time measure- ment;
  • Systems with especially narrow sound cone for the detection of small objects or of objects with extremely small openings;
  • Systems with teach-in function on the device and /or by cable Systems with adjustable switching frequency or sound cone shape.
