Introduction

PCW1J-B24-BAB102L is a type of rotary potentiometer, or rheostat, used in a variety of fields. It is a device capable of altering or adjusting the resistance of an electrical circuit with a rotary motion. It was first developed at the end of the 19th century and has developed ever since.

Application Field

The rotary potentiometer PCW1J-B24-BAB102L is mostly used in the frequency control or resistance control, such as adjusting the frequency of an oscillator, or adjusting a mechanical device as an adjustable resistor. It is also used in audio and video equipment for volume and tone control, as well as in laboratory and industrial equipment.

Working Principle

ThePCW1J-B24-BAB102Lis composed of a resistive element, a tracking mechanism, and a control mechanism. Through the rotation of the rotary shaft, the parameter of change will be proportional to the angle of rotation of the rotary shaft. The resistive element consists of a set of resistors connected in series. As the knob of the potentiometer is turned, the sliding contact, known as the wiper, moves across these resistors, and the resistance between the wiper and one of the terminals changes. This resistance value is converted to a voltage signal, and the signal is fed to the control circuit to adjust its operating parameters.

Conclusion

The rotary potentiometer PCW1J-B24-BAB102L has wide applications due to its simple structure and easy operation. It is mainly used in frequency control or resistance control, and also in audio and video equipment, laboratory and industrial equipment. Its working principle is that, through the rotation of the rotary shaft, the parameter of change will be proportional to the rotation angle of the rotary shaft.
