5 Pin Round Dial Potentiometer Rotary Volume Control Switch 50K 16mm

Description

Round Dial Potentiometers are variable resistors whose resistance can be varied by moving the handle linearly from one end to another. This item includes 50K potentiometers with a common ground. It has a nice big 16mm diameter dial which can be used to manually adjust the required resistance. This potentiometer is popularly used in radios and stereos. This is basically a variable resistor, which means when the handle is at one end the resistance is 0 ohms. Moving the handle towards the other end will change the resistance towards 50K as per the handle movement. Can be easily connected to the analog pin on an Arduino or a Raspberry Pi to get the handle position. But is great for controlling lights or a fan, linear encoder, etc.
