Sensofoil® FR4-Magnet

Resistive track printed on circuit board

  • 0 °C bis +55 °C
  • contactless operation
  • placement of additional electronics possible

Magnetic potentiometers can also be manufactured on FR4 material. The integrated ferromagnetic material creates a magnetic pull, strong enough to work through an enclosure using the appropriate magnet. This technology allows for contactless and wear-free operation. Due to the circuit board, the Sensofoil® FR4-Magnet provides various mounting options besides the standard adhesive film.


  • IP Rating up to IP54
  • Life cycle up to 20 million operations
  • Contactless operation
  • Easily adapted to customer specific design
