ifm efector ultrasonic sensors

With ultrasonic sensors, colour, transparency or the object’s surface shine do not play a role in the detection. Blister packages in packaging technology or transparent plastic bowls in the food industry, for example, can be reliably detected.

The ifm ultrasonic sensors in M18 design provide a particularly small blind zone (only in the diffuse version) and long sensing ranges, which are usually only achieved by sensors of a considerably larger design. In the case of the retroreflective version there is no blind zone.

The sensors operate reliably with heavy soiling so that they can be used in applications in which photoelectric sensors meet their limits. The vibrations from the sonic transducer also assist with the reduction of soil build-up on the measuring face. The ultrasonic sensors also have a scratch-resistant surface.

The ifm ultrasonic sensors can be easily set up using any one of three methods: through a teach button on the sensor; via a direct connection to a PLC; or via IO-Link making them Industry 4.0 (IIoT) ready.

The ifm ultrasonic sensors are available in diffuse and retroreflective versions, and with 1.2 m and 2.2 m sensing distance options. Digital (PNP and NPN), analog (4–20 mA and 0–10 V) and IO-Link outputs are available. M8 cube and M18 cylindrical body designs offer various mounting options, and long and short body versions are available in both plastic and stainless steel.
