Large Slider Potentiometer 20K ohm

The Large Slider Potentiometer 20K ohm is a slide potentiometer with a 20 kΩ resistive track and a lever that moves in a straight line instead of turning. The lever position is easy to see and set by hand, so it is a natural choice for faders and control panels where the user should read the setting at a glance. The 20 kΩ value keeps the current through the track low while still giving steady readings on an Arduino or ESP32 analog input.

Large Slider Potentiometer 20K ohm Specifications

• Type: slide (straight-travel) potentiometer, large size
• Resistance: 20 kΩ end to end
• Control: lever moved along a straight track
• Function: the wiper picks off any voltage between the two track ends
• Track current at 5 V: about 0.25 mA

Large Slider Potentiometer 20K ohm Applications

• Fader-style controls for mixers, lighting desks and control panels
• MIDI controllers and DIY control surfaces
• Speed, brightness or position input for Arduino and ESP32 projects
• Adjustable reference voltages on the workbench
• Electronics classes and STEM demonstrations

What's in the Box

• 1 × large slider potentiometer, 20 kΩ

Tip: Connect the two track-end pins to 5 V (or 3.3 V) and GND and the wiper pin to an analog input; an Arduino Uno then reads 0 to 1023 along the travel. Check the pin markings on the body, as the pin layout varies between slider models.
