Multiturn Potentiometer 20K ohm

The Multiturn Potentiometer 20K ohm is a fine-adjustment variable resistor with a 20 kΩ track. Its adjuster needs several full revolutions to move across the whole track, so each turn changes the resistance only a little and a setting can be made precisely and repeated. The 20 kΩ value is a versatile choice for calibration, gain setting and precise analog inputs on Arduino and ESP32 boards.

Multiturn Potentiometer 20K ohm Specifications

• Type: multiturn potentiometer
• Resistance: 20 kΩ (20,000 ohms) end to end
• Adjustment: several full turns across the track for fine control
• Connections: two track ends and a wiper
• Track current at 5 V: about 0.25 mA

Multiturn Potentiometer 20K ohm Applications

• Fine analog input for Arduino and ESP32 projects
• Op-amp gain and offset adjustment
• Setting comparator thresholds, for example with the LM393
• Calibrating sensor, thermostat and meter circuits
• Electronics labs and experiments

What's in the Box

• 1 × multiturn potentiometer, 20 kΩ

Tip: Connect the two end pins to 5 V and GND and the wiper (usually the middle pin, check the markings) to an analog input. A 20 kΩ pot has an output impedance of at most 5 kΩ, so it drives the Arduino Uno ADC directly with steady readings.
