The Controltec division at steute Technologies focused on two goals in redesigning the RF IS FL radio inductive sensors. The first: the cylindrical sensors in diameters M 8, M 12, M 18, and M 30 are now also suitable for flush mounting. This was not previously possible because battery-powered wireless inductive sensors with a fixed switching point detect the surrounding metallic material in such cases and switch accordingly. This has unfortunately often ruled out their use in some applications, such as the detection of handled goods in robot grippers or the detection of workpieces in machine tools or assembly and handling units.

steute engineers were able to open up these additional areas of application by developing the latest generation as FLexible sensors with digital auto-calibration. This means that the inductive sensors are no longer equipped with a fixed switching point, but automatically and dynamically adjust their switching point to the respective conditions. This also includes distinguishing between flush and non-flush installation. The sensor technology can even adapt to dynamic changes such as increasing contamination. The sensors are therefore always ready for use and only switch when the situation or the operator's request requires it.

The second optimization goal—reducing energy consumption—was also achieved. Certain measures have significantly extended the battery life in the universal radio modules, which are suitable for connecting up to four RF IS FLs. Overall, energy consumption has been reduced by up to 80 percent compared to the previous model.
