Potentiometers for Extreme Temps & Environments

Operating in high temperature environments calls for a more reliable heat resistant position sensor or potentiometer. Spectra Symbol’s HotPot potentiometer makes reliable mechanical control or tracking movement in a volatile environment easier. It has a thin and sealed form factor that allows it to operate at temperatures ranging from -40°C to +85°C. This feature makes the HotPot an ideal heat resistant potentiometer or position sensor for industrial, military, and automotive applications. Design engineers choose the Spectra Symbol HotPot because of its robust design and high life cycle output.

Made from impregnated fiberglass material, the Spectra Symbol HotPot potentiometer is highly resistant to temperature fluctuations. It operates either via direct actuator contact, finger contact, or ideally a wiper or plunger under controlled pressure for maximum reliability.

The Hotpot is an invaluable tool for applications that require precise control or absolute position sensing when the environment it is operating in is less than gentle. You can combine multiple HotPots in a single control panel. You can change the resistance by simply pressing down on different parts of the strip, which can measure up to 1000mm+. By changing the resistance, you can easily calculate the relative position on the strip.
