U1KT003 Distance Sensor

available on request
These ultrasonic sensors evaluate the sound reflected from the object. They detect almost any object regardless of the material and its condition. They are therefore especially well suited for monitoring fill levels of liquids and bulk goods and for detecting transparent objects. The measured value can be read out via IO-Link, and the sensor can be optimally adapted to the application. The sensor can be used in reflex mode operation and as an ultrasonic through-beam sensor.
