Turck adds IO-Link to ultrasonic sensors
March 2018, Sensors & Transducers

Turck has added a variant with an IO-Link output to its basic Compact series of ultrasonic sensors. Users can use IO-Link for the process values or continue to use the switching output of the sensor. The switch point is taught via IO-Link or via a teach adaptor as before. Besides the known benefits of IO-Link, such as inexpensive wiring, intelligent data retention and predictive maintenance, the sensor offers a special mute function feature. This enables the selective switching on or off of the sonic transducer via the IO-Link master. This simplifies the synchronised or staggered operation (multiplex) of several sensors via the controller. Synchronous or multiplex operation was previously only possible by using complex wiring solutions.

The compact RU-U sensors with IO-Link are available as diffuse mode or retro-reflective sensors in the M18 housing in straight or angled designs with ranges of 40 and 100 cm.

Turck’s RU ultrasonic sensor series consists of three product lines: the compact version, the standard version or the high end version. The three lines have different sets of functions and output options. The optimised control electronics gives the entire series large ranges with short blind zones. The smooth sonic transducer front prevents the collection of dirt and moisture.
