1M ohm 16mm Rotary Pot Variable Potentiometer

• This is a 16mm size 1M ohm rotary potentiometers (plastic shaft).
• Turn the pot 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 rotation of the pot.
• This is used for adjusting various parameters like voltage, current, etc. in an electronic circuit.
• It has a tolerance of 20%.

Potentiometers play a crucial role in modifying the electrical characteristics of a system. The described potentiometer is a single-turn 1M potentiometer equipped with a rotating knob, often referred to as a rotary potentiometer or simply “POT.” For aesthetic reasons, a knob can also accompany this POT.

This potentiometer features a carbon track and is a single-turn adjustable resistor with a value of 1M Ohm. Designed for panel mounting, it comes complete with an attached knob. The knob, fixed to the plastic spindle of the potentiometer, rotates the spindle, thereby altering the resistance. The resistance variation is directly proportional to the rotation degree. In electronics, a potentiometer is essentially a manually adjustable resistor. Although commonly used to control sound volume or tone in receivers, it’s colloquially termed “volume” or “tone.” Unlike a meter with a scale and needle, potentiometers’ appearance varies based on factors like size, power capacity, application, resistance value, and material type. Nonetheless, they all share a common trait: a wiper that moves across a resistive material length. Both ends of this material, along with the wiper, serve as electrical connection points, allowing users to access variable resistance between the wiper and the two ends.
