Flat, wear-free and hermetically sealed: SENSOFOIL® membrane potentiometers from Hoffmann + Krippner are ultra-flat and very accurate linear and rotary position sensors. They can be used instead of conventional mechanical potentiometers and work as voltage dividers. In comparison to mechnical potentiometers, Sensofoil ® offers significant cost advantages as well as a much longer lifecycle.

Due to their flat design of 0.7 mm (0.027 in.) to 1.7 mm (0.066 in.) and their simple adaptation to customer requirements, SENSOFOIL® membrane potentiometers from Hoffmann + Krippner are the ideal solution for restricted installation conditions.

The technical specifications of the SENSOFOIL® membrane potentiometers correspond to those of conventional precision potentiometers or even surpass these. They offer an attractive cost advantage and are easy to use.

Standard elements of 50 mm to 500 mm are available, as well as very favorably priced customer-specific variations. In particular the good repeat accuracy, the easy to achieve redundancy and the problem-free integration into new and existing designs represent decisive advantages.

SENSOFOIL® follows the shape and function of the specific application: linear, circular or customer-specific shapes are available, also available with non-contact connection (SENSOFOIL ® Magnet).

Depending on various parameters, the service life comprises 1 million operations to 60 million operations and the repeat accuracy 1 mm to 500 µm. All SENSOFOIL® standard products are sealed to IP 65/NEMA 4X, enhanced sealing is available as well.
