F90 – Intelligent linear path measurement system

... with high accuracy and resolution, even in harsh environments – has that always been a wish of yours, but only a wish? Now the new intelligent F90 linear path measurement system from Pepperl+Fuchs can make your wish come true.

Proximity switches have been used for years in industry, proving their reliability in the most wide-ranging applications. As the result of constant change and higher requirements, however, continuous position sensing is demanded more and more frequently instead of simple binary signals. Now Pepperl+Fuchs has combined these requirements with the proven capabilities of inductive sensors and has created an extremely reliable inductive linear path measurement system that easily masters even critical positioning tasks.

The new Pepperl+Fuchs sensor system F90 is based on a highly precise evaluation of a number of coil systems. The basic version returns a continuous current and voltage signal. In addition to extremely high resolution and accuracy, the F90 also boasts a minimal temperature drift, thanks to its integrated temperature compensation. Unlike conventional systems, the F90 linear path measurement system is not linked to a ferrite target. The activator can be designed in any type of metal, just as for an inductive proximity switch. An advantage compared to conventional path measurement systems based on the magnet inductive principle is insensitivity to horizontal shifting of the target and vibration. These do not result in any loss of accuracy for the F90.

Beyond the analogue current and voltage output of the basic version, the convenience version also offers two separate switching points that can be programmed directly on the device with a teach-in process.
