Ultrasonic proximity sensors use sound waves to detect an object or measure distance and are unaffected by color, transparency, shininess, or lighting conditions. These cylindrical sensors come with both discrete (presence) and analog (distance) outputs, offer detection ranges up to 400mm, and integral 2m pigtail cable or quick-disconnect termination (model-dependent).
Ultrasonic sensors are ideal for applications in which the sensed object is made of clear, transparent or varying surface color materials. You can standardize on one sensor for many materials, without any extra setup or sensing concerns.
