THINPOT
Spectra Symbol is a premier source for high quality linear position sensors. We offer a range of potentiometers with varying features to suit any application. Our line of linear sensors includes the ThinPot, a component that serves as a variable analog voltage divider. This membrane potentiometer measures 10mm wide and 0.5mm thick, making it ideal for applications in even the most difficult locations. It has all the features offered by the SoftPot, but is narrower. this sensor operates in linear or rotary configurations and is available in lengths of up to 2400mm.

What is a ThinPot?
In simple terms, the ThinPot membrane potentiometer is a resistive element, which comprises a conductive resistor, a sealed encasement and a simple wiper assembly. A membrane potentiometer can also function as a voltage divider.
The ThinPot is a three-wire system with two resistive output channels and an electrical collector channel.
By pressing a wiper down onto the top circuit the ThinPot produces the desired electrical output.
The “wiper” is a non-conductive mechanism that depresses the top circuit actuating the potentiometer from the outside of the element. The top and bottom circuits are separated by 0.15mm (0.006″) of spacer adhesive build-up and contact between the circuit occurs by pressure (usually 1-3 Newtons) from the wiper on the top circuit, pushing down until the top circuit connects with the bottom circuit to create a potentiometric output.
The construction of the wiper design can adapt to any application because most materials can serve as the wiper: plastics, metals, sliders, rollers, wheels, etc. Also, the ThinPot can also be manually (hand) actuated.

What Is ThinPot™?
The ThinPot™ is a membrane potentiometer – a variable analog voltage divider – designed with simplicity and adaptability in mind. The sensor features a flat resistive element sealed between two flexible layers, activated by pressure from an external wiper.
It’s a three-wire system, composed of:
-
Two resistive output channels
-
One electrical collector (wiper signal) channel
When pressure is applied to the surface, typically by a non-conductive wiper, the top layer is pushed down to make contact with the bottom layer, producing an accurate analog output signal. The spacer between the layers is just 0.15mm (0.006″), enabling rapid and reliable response with just 1–3 Newtons of force.
Why Medical Innovators Trust ThinPot™
Medical devices demand components that are:
-
Compact and lightweight
-
Highly accurate and repeatable
-
Resistant to environmental challenges
-
Easy to integrate with minimal intrusion
The ThinPot™ delivers on all fronts. It has become a standard sensor in critical medical equipment for its performance in:
-
Oncology therapy systems (linear position feedback)
-
IV infusion systems (volume and rate control)
-
Surgical tools (precise hand-actuated feedback)
-
Patient monitoring devices
Unmatched Flexibility and Customization
The ThinPot™ is designed with versatility in mind. Its wiper design can be adapted to a variety of materials including plastics, metals, sliders, wheels, rollers, and even manual touch (finger actuation). This flexibility makes it perfect not only for medical applications, but also for industrial, aerospace, and automotive use cases.
