A new smart sensor from IFM alerts users to maintenance issues it says would otherwise only become obvious when it’s too late.

“Its high resolution allows the sensor to detect even tiny changes in the switching area,” the company said in a statement.

In addition to its position sensor functions, it also provides additional information for condition-based maintenance in the user’s installation. The MQ2 continuously detects ferromagnetic objects in front of its active face. It signals soiling via IO-Link when the current value exceeds the set threshold so that cleaning can be arranged.

The same applies to changes in the switching area, for example those caused by mechanical wear. The integrated operating hours and switching cycles counter allows the provision of a signal if the selected number of switching operations has been reached, enabling targeted maintenance of tools.
