Due to their technical specification they meet the requirements of convetional precision potentiometers or even show better cha- racteristics. Excepting the standard product range are numerous customer specific solutions available. Membrane foil potentiometers are used successfully since fairly long time in different industries.

4 In the robotic indust- ry cylinders and actuators can use it to determine accurate positions. Numerous applications have been realised also in medical devices. They are used as manual input systems, as well as for the determination of precise measurement values, for instance, in pumps. In automotive applications Membrane foil potentiometers can control for instance, the convertible hood or the electrical seat adjustment. Doorsystems can be controlled and monitored by foil potentiome- ters. Also the use in locking cylinders as well as in electrical doors is realizable with this components. ordering informations Detailed information: LSF 25 2,5k F1.
