Introduction

Trimmer potentiometers are electrical components that are used to set and adjust desired levels of electrical circuits and systems. The RJR24FP105R is one of the more popular trimmer potentiometers, and is widely used in many applications. This article discusses the application fields and working principle of the RJR24FP105R, to provide insight into its capabilities and understand how it functions.

Application Fields of the RJR24FP105R

The RJR24FP105R is a general-purpose trimmer potentiometer, which is suitable for a variety of circuit design needs. It is often used as a voltage divider to provide adjustable voltage control, and to increase or reduce resistances for current flow. It is also used as a positional sensor, and can be found in VU meters, which measure audio signals from production and broadcasting equipment. Additionally, the RJR24FP105R is helpful in motor speed regulation and can be used to customize the response of various sensors.

Working Principle

The RJR24FP105R functions by separating the internal potential equal to the applied voltage in proportion to the contrast between the resistance of its resistive elements - R1, R2 and the contact resistance of R3. The RJR24FP105R has two sets of leads, the first two R1, R2, form a resistor network that is used to create the voltage division, the third R3 is the element used to adjust the level of resistance. When an external voltage difference is applied, a current flows through R1, R2, and the resultant electromotive force between two points drives the current Y. As the position of the contact moves, the resistance of R3 changes, and the balance of the current flows through R1, R2, R3, and the resistance changes. This position can be used to set or adjust the voltage or current levels.

Conclusion

This article discusses the application fields and working principle of the RJR24FP105R, a popular trimmer potentiometer that is widely used in various electronics fields. The RJR24FP105R is capable of dividing and adjusting voltage levels, as well as regulating motor speed and customizing the response of various sensors. It works through the variation of the resistance between R1, R2 and R3.
