Membrane Potentiometer operates in complete vacuum environments.
Press Release Summary:
Constructed from PET, FR4 and Kapton materials, SENSOFOIL® Hybrid membrane potentiometer can be used in complete vacuum environments and at temperatures up to 125°C. While standard linearity is around 2%, it can get as low as 1% with PET materials and 0.5% with FR4 and Kapton materials. It can be produced in linear, rotary, or customer specific shapes. Wiper design delays denting effects and soemtimes returns foil back to its original state after denting occurs.

Next-Generation SENSOFOIL® HYBRID Membrane Potentiometer Sets the Standard in Ultra-Flat Position Sensing
Peachtree City, GA - Hoffmann + Krippner Inc.'s SENSOFOIL® is an ultra‐thin membrane potentiometer that can be used to replace larger, more expensive mechanical potentiometers in a variety of applications. The newest addition to the SENSOFOIL ® product line is the next‐generation SENSOFOIL® Hybrid (Patent Pending), which utilizes a new technology that is not available from any other company. Unlike existing membrane potentiometers, this technology allows the SENSOFOIL® Hybrid to be used in complete vacuum environments. In addition to their successful operation in this type of environment, they can also be used at temperatures up to 125°C (257°F).
Constructed from PET, FR4 and Kapton materials, the SENSOFOIL® Hybrid can be produced in linear, rotary, or customer specific shapes. While standard linearity is around 2%, it can get as low as 1% with PET materials and 0.5% with FR4 and Kapton materials.
SENSOFOIL® potentiometers exhibit excellent repeat accuracy and hysteresis. Another advantage of the SENSOFOIL® Hybrid involves the wiper. Typically, standard PET‐based membrane potentiometers are operated with a mechanical wiper that makes contact with the collector foil. When the wiper experiences prolonged periods of standstill at high temperatures, the collector foil can become dented. The SENSOFOIL® Hybrid will allow a
delay in these denting effects and in some cases will return the foil back to its original state after the denting occurs.
Hoffmann + Krippner SENSOFOIL® products can be purchased at a very competitive price when compared with other standard mechanical potentiometers that are available.
