UMD123U035 Distance Sensor

available from stock
These ultrasonic sensors evaluate the sound reflected from the object. They detect almost any object regardless of the material and its condition. Thanks to the innovative transducer, this sensor has a particularly wide sonic cone at close range. This allows a very wide range of pieces to be reliably detected on conveyor belts.
