U1RT004 Distance Sensor

available from stock
These ultrasonic sensors evaluate the sound reflected from the object. They detect almost any object, regardless of material, state, color or transparency. 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.
