In addition to foil material, we offer versions with base material FR4, which is known from circuit board production. This completes the wide range of properties of the membrane potentiometer. The use of FR4 increases the stability of the element and the variability of the connections.Customer-specific requirements can also be mapped for the designs. This applies to length, angle, shape, connection area or additional functions such as impulse switching points.A special feature is the width of linear elements. The standard width is 22 mm. Common sensors are reduced to a width of 10-13 mm. A width of 9 mm is also possible with our foil potentiometers.The membrane potentiometer is available with an effective area of 50-500 mm as standard. Shorter distances are also possible on customer request. Rotary membrane potentiometers are available from an outer diameter of approx. 40 mm. There are already a number of available standard measuring angles.Since the sensors are very flat (from 0.5 mm), these potentiometers are an ideal addition to our range, which also represents a cost-optimized alternative, especially in cramped installation conditions.
Foil Membrane Potentiometer
Foil Membrane Potentiometer for Industrial Applications
The foil membrane potentiometer is a robust and versatile sensor solution for applications requiring precise position or angle measurement in confined spaces. Its flat design, starting from only 0.5 mm thickness, makes it an excellent choice where traditional potentiometers with housings cannot be used effectively.
Reliable Design and Flexible Options
By combining foil membranes with optional FR4 base materials—commonly used in circuit board manufacturing—these membrane potentiometers offer enhanced stability and flexible connection options. They are suitable as voltage dividers and can be customized to meet specific requirements regarding length, angle, shape, or additional functions such as impulse switching points.
