500Ω Rotary Precision Potentiometer 3590S-2-501L - (AD56786)

Description:

An adjustable potentiometer can open up many interesting user interfaces. Turn the knob 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 potentiometer's rotation. Hook the center pin to an ADC on a microcontroller and get a variable input from the user! This is a precision 10-turn multi-turn potentiometer.

Electrical characteristics:

- Standard resistance range: 500 ohm
