Sensofoil® Membrane Potentiometer

Sensofoil® FR4-Hybrid

Resistive track printed on circuit board – integrated metal strip for higher temperature resistance and longer life cycle

The Hybrid technology already mentioned for Sensofoil® potentiometers on PET can also be implemented on circuit boards. The PET layer with printed resistive track is simply replaced by the FR4 material. The Sensofoil® FR4-Hybrid was specifically developed for high operating temperatures of up to +105°C. The integrated, flexible metal strip is what makes this potentiometer particularly robust.

How does it work?

The operating principle of the Sensofoil® PET-Hybrid can be applied to the Sensofoil® FR4-Hybrid as well. The base membrane is replaced by a circuit board, providing further connecting and mounting options. The FR4 board can also be equipped based on customer requirements.
