Description: An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center pin to an ADC on a microcontroller and get a variable input from the user!

This pot has a ¼" mounting diameter and has a 10K logarithmic taper. Check the datasheet for dimensional drawings.

  • Also, are these true Logarithmic pots, or simulated logarithmic pots?

    Ive been looking for one forever, but they were always out of stock.

  • These are reverse logarithmic pots - C10K. Is there any way to order A10K pots?

  • unlikely mate,
    “A logarithmic taper potentiometer has a resistive element that either ‘tapers’ in from one end to the other, or is made from a material whose resistivity varies from one end to the other. This results in a device where output voltage is a logarithmic function of the mechanical angle of the potentiometer.
    Most (cheaper) "log” potentiometers are actually not logarithmic, but use two regions of different resistance (but constant resistivity) to approximate a logarithmic law. A logarithmic potentiometer can also be simulated with a linear one and an external resistor. True logarithmic potentiometers are significantly more expensive.“ - wikipedia
