Ultrasonic sensors transmit and receive sound waves in the ultrasonic range. The object to be detected reflects the sound waves and the distance information is determined via time of flight measurement. As opposed to photoelectric sensors colour, transparency or the object’s surface shine do not play a role. Blister packages in packaging technology or transparent plastic bowls in the food industry can be reliably detected.
The ifm ultrasonic sensors in M18 design provide a particularly small blind zone and long sensing ranges up to 2,2 m, which are usually only achieved by sensors of a considerably larger design. The round and cube designs are available in a plastic or a particularly robust high-grade stainless steel housing.
The vibrating sound transducer reduces the deposit of dust. The sensors operate reliably with heavy soiling so that they can be used in applications in which photoelectric sensors meet their limits. They are set to the application via teach button, wire teach or IO-Link. Besides the sensors with the diffuse reflection principle ifm also offers versions for retro-reflective operation for orientation-independent object detection, for example wire mesh.
