Trimmer Potentiometers

Trimmer potentiometers are variable resistors that are used to tune or adjust electrical signals to the desired level. They are most often used in operational amplifiers (op-amps) as well as other applications such as radio receivers, clocks, and tachometers. The 84PR20KLFTR is one such trimmer potentiometer. This section examines the application field as well as the working principle of the 84PR20KLFTR.

Applications

The 84PR20KLFTR is a contactless trimmer potentiometer. It has a wide range of possible applications, including audio production equipment, volume controls, and various frequency-dependent circuits. It is also applicable in low-power amplifiers, power supplies, adjustable filters, and adjustable regulators, as well as in automation, communications, and instrumentation systems. The 84PR20KLFTR is also a good choice for applications that require flexibility or ease of adjustment, such as temperature or pressure control systems.

Working Principle

The 84PR20KLFTR is a non-contact trimmer potentiometer. It uses a rotary mechanism with a flexible plastic wheel to control the electrical connection. The wheel is mounted to a control shaft that is rotatable in either direction. The outside of the wheel is coated in a conductive material that is connected to the supply voltage of the circuit.As the wheel is rotated, it moves across the surface of the trimmer potentiometer, creating a variable resistance. The amount of resistance is directly proportional to the angle of rotation since the more conductive material is exposed, the higher the resistance. The overall resistance of the trimmer potentiometer is determined by the distance between the contacts and the wheel, as well as the size and shape of the wheel itself.

Conclusion

The 84PR20KLFTR is a versatile trimmer potentiometer with a wide range of applications in both commercial and industrial applications. The non-contact design allows for easy adjustment without the need for complex internal mechanisms. Its ability to produce a variable resistor is determined by the distance between the contacts and the wheel, as well as the size and shape of the wheel itself. The 84PR20KLFTR is an excellent choice for any application requiring a trimmer potentiometer with an adjustable resistance.
