Hannover Fair 2005: Pepperl+Fuchs exhibits intelligent linear path measurement

Hannover, Germany— To provide accurate, high-resolution, non-contact position sensing, even in harsh environments, Pepperl+Fuchs is exhibiting its intelligent F90 linear path measurement system at Hannover Fair 2005 this week.

Proximity switches already have proven their reliability in the many applications, but continuous position sensing is being demanded more frequently than simple binary signals, according to the company. Consequently, Pepperl+Fuchs reports that it has combined these requirements with the proven capabilities of inductive sensors, and created a reliable inductive linear path measurement system that masters even critical positioning tasks.

F90 is based on precise evaluation of several coil systems. The basic version returns a continuous current and voltage signal. Besides high resolution and accuracy, F90 also features minimal temperature drift, due to its integrated temperature compensation. Unlike conventional systems, F90 isn’t linked to a ferrite target. The activator can be designed in any type of metal, similar to an inductive proximity switch. Another advantage over conventional path measurement systems, based on the magnet inductive principle, is F90’s insensitivity to horizontal shifting of the target and vibration, which don’t cause F90 to lose any accuracy.

Beyond the analog current and voltage output of the basic version, F90’s convenience version also offers two separate switching points that can be programmed directly on the device with a teach-in process.
