SENSOFOIL: Ultra-flat membrane potentiometer as linear and circular sensors from Hoffman + Krippner
Flat, wear-free and hermetically sealed: the Sensofoil membrane sensors from Hoffmann + Krippner represent the ideal functional level for linear and rotational potentiometers and sensors.
Due to their flat design of 0.5 mm to 1 mm 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 favourably priced customer-specific variations, In particular the good repeat accuracy, the easy to achieve redundancy and the problem-free integration represent decisive advantages.
Sensofoil® follows the shape and function of the specific application: linear, circular or customer-specific shapes are available, on request also with non-contact connection.
Depending on various parameters, the service life comprises 1 million cycles to 60 million cycles and the repeat accuracy 1 mm to 10 µm. The standard products are sealed to IP 65.
