This is a multiturn potentiometer with a resistance rating of 2.5M ohms. Unlike single-turn potentiometers, multiturn potentiometers offer multiple turns of the shaft for more precise and fine-tuned resistance adjustments. The resistance makes it suitable for applications where accurate and repeatable adjustments are necessary. This multiturn potentiometer is commonly used in electronic circuits and projects that require fine control over voltage or signal levels. The extended rotational range allows for increased precision in setting resistance values.
