Plant designers have long had to use different types of sensors or deal with time-consuming reconfiguration when tasked with detecting objects made of different types of metal. Standard inductive sensors can only detect non-ferrous metal targets at reduced switching distances. This is because reduction factors can vary from one metal to another. Pepperl+Fuchs’ reduction factor 1 sensors circumvent this issue and unify switching distances for all types of metals.

The expanded portfolio of reduction factor 1 sensors can give a boost in welding areas, standard usage, and for applications that require cleaning operations-with or without IO-Link. Pepperl+Fuchs’ inductive sensors with IO-Link offer identical switching distances for all metals and new installation, diagnostics, and maintenance capabilities using the IO-Link device connectivity.

New reduction factor 1 sensors with IO-Link configure via the PLC while data control functions can ensure automated reconfiguration through an IO-Link master in case a device needs to be replaced. The new sensors prove themselves in applications with mechanical tolerances that would lead to detection issues with standard sensors, and now with the IO-Link sensors’ stability alarm, the system can be triggered in the event the activation target drifts outside the assured operating distance. This function not only makes commissioning easier with a flashing integrated LED for visual indication of assured setup, but also makes predictive maintenance possible. If an activation target drifts from the assured operating distance due to mechanical influences-the intelligent sensor detects this condition, the integrated LED flashes, and the signal is automatically transferred to the control system. This is how intelligent sensing via IO-Link and the control system is used for smart automation and diagnostics in the modern application era.

If necessary, a reduction factor 1 sensor can serve as a temperature indicator that shows whether it is operating within the specified temperature range, or whether it is being exposed to a critically high temperature. These indicators provide early detection of temperature increases before the sensor or other sensitive system components, like those found in paint shops or foundries, may be damaged. With the help of the stability alarm and the temperature indicator, pre-failure information is continuously communicated so maintenance can be carried out prior to sensor fault.
