Trimmer Potentiometers

The 91AR2MEGLF is a type of trimmer potentiometer that is commonly used for many purposes, including audio signal gain control, DC motor speed control, and position control of robotic arms. Trimmer potentiometers are adjustable resistances or some type of voltage/current regulators, wherein the resistance or regulator level can be adjusted through manually turning the knob or shaft.

Application Field

Trimmer potentiometers are widely used to precisely adjust parameters in a circuit. A trimmer potentiometer consists of a small wiper coupled with a slowly rotating shaft, the resistance value or the voltage/current level is adjusted by the amount of rotation of the knob or shaft.

The 91AR2MEGLF trimmer potentiometer can be used to precisely adjust various parameters in many circuits. For example, it can be used to adjust the DC motor speed, the signal strength and gain in audio input circuits, and to precisely tune parameters in other controls.

Working Principle

Trimmer Potentironics 91AR2MEGLF is a 3-terminal variable resistor, the working principle is quite simple. When the knob rotates clockwise or counter-clockwise, it is connected to one of the outer terminals, and the wiper is connected to the center terminal, thus, the resistance between the outer terminals can be adjusted by turning the knob.

Due to its low-power and low-cost design, the 91AR2MEGLF is suitable for various types of control applications such as signal gain control, DC motor speed control, as well as robotic position control.

Conclusion

The 91AR2MEGLF is a 3-terminal trimmer potentiometer that is used to precisely adjust various parameters in a circuit. Its low-power and low-cost design make it an ideal choice for various types of control applications such as signal gain control, DC motor speed control, as well as robotic position control.
