Description: When you need to track movement in a volatile environment, HotPot provides a thin and sealed form-factor with operating temperature tolerances of -40 to +85C. The HotPot is the preferred product for industrial and outdoor applications. By pressing down on various parts of the strip, the resistance linearly changes from 100Ohms to 10,000Ohms allowing the user to very accurately calculate the relative position on the strip. Can be used as an accurate positional indicator for CNC head positioning, variable user input (volume level input for example), straight user input (multiple button areas translate to given resistance levels), and many other applications.

The HotPots are ideal for higher temperature environments, but many users also find that the HotPots which are made out of a impregnated fiberglass material, ‘feel’ better than the SoftPots which are made out of a polyester base. If you’re planning on using these pots with finger contact (versus with the actuator), you may want to consider using the HotPot line.

Unit comes with adhesive backing. Connector is 0.1" spaced and bread board friendly.

Note: These potentiometers work great with a finger, or stylus. For premium repeatability, the wiper listed below is perfect for machine and object positioning.

Customer Comments

  • What’s the connector on the end? Is there a corresponding socket we can get?

    • It’s just a basic 3-pin connector with 0.1" spacing. It can be plugged into a breadboard, though I’ve had difficulty plugging it into female headers-the tension isn’t great enough to keep it inserted. Otherwise customers generally just solder regular headers to those pins or jumper wires.

  • more size choices would be great. i’ll experiment with the softpot, but I have a feeling they’ll not meet the demands of my project due to the harsh environment it will be used in.

I can not assess the reason I have not received. At the time of purchase I was in the USA, spent two days in exception and then the snow did not allow me to receive in time. Has arrived in the USA office, but I’ll have to wait a while yet. Why all the purchases made in sparkfun enter the exception status?
