1M Ohm Linear Potentiometer

1M Ohm Linear Potentiometer 

The 1M Ohm Linear Potentiometer is a variable resistor designed for smooth, proportional adjustment of high-resistance values. Its linear taper ensures that resistance changes evenly with shaft or slider movement, making it ideal for precision voltage control, analog signal tuning, and calibration tasks. This potentiometer is commonly used in sensor circuits, audio applications, microcontroller projects, and other electronics requiring high-resistance adjustment.
