Foil Potentiometer Sensofoil®

Sensofoil® membrane potentiometers are ultra-flat and very accurate linear and rotary position sensors.

The potentiometer offers flexibility,  a diverse range of solutions can be achieved. Due to its compositions, the ultra-flat design, and the easily adaptable features, Sensofoil can be conveniently integrated into existing applications.

With Sensofoil® the collector foil is always in place to function as electrical tap. A mechanical plunger in the form of a wiper or magnet forms the electricalcontact between the resistor track and collector (tap).

Sensofoil is available in different types – precisely tailored for your individual needs:

  • Sensofoil PET – The ultra flat membrane potentimeter for temperature ranges between -40°C to +55°C
  • Sensofoil HYBRID – The longlife membrane potentiometer for high temperatures up to 105°C and vacuum-enabled operations
  • Sensofoil MAGNET – The membrane potentiometer for non-contact operations via magnet
  • Sensofoil FR4 – The membrane potentiometer for needs of alternative mounting or alternative connections
  • Sensofoil MODULE – The modular membrane potentiometer solution for almost any customer application
