Wenglor UMS303U035, Distance Sensor

These ultrasonic sensors evaluate the sound reflected from the object. They can detect almost any object and are especially well suited for monitoring fill levels of liquids and bulk goods and for detecting transparent objects. The sensor detects objects regardless of material, state of matter, color or degree of transparency. The graphical display is menu-guided for easy setup of the sensors. The IO-Link interface makes parametrization and diagnosis quick and easy. The sensor can only be used in reflex mode operation.
