Introduction

The PTD902-1015K-B504 is a rotary potentiometer, rheostat that is ideal for a variety of general-purpose applications. This device is specially designed to provide linear actuation characteristics, allowing user to adjust the resistance value between 0 and 10K ohms at a range of up to ±5K ohms. It also features a low power consumption rating to help conserve energy. Furthermore, this unit offers excellent accuracy and response time, making it an excellent choice for applications that require precise resistance adjustment.

Application Field

The PTD902-1015K-B504 can be used in a wide range of applications, such as volume control, gain control, light dimmer, low pass filter, audio balance control and power switch, as well as being able to adjust the speed of a motor or help to adjust the brightness of an LED. This device is especially suited for applications which need a large or precise range of resistance control.

Working Principle

This unit has a simple working principle; the user turns the knob to create a resistive path with the help of terminals provided. As the resistance path is increased, the electrical charge travelling through it is lowered. This resistance path is indicated by the resistor or LED (depending on the application) connected to it. The connected device will thus indicate how much resistance is present.

The potentiometer is made up of an electroconductive wiper, that is set in motion by rotating the knob, to come into contact with the resistance ladder, which is physically created in the body of the potentiometer itself. This ladder is made of a set of resistive strips leading from one side of the potentiometer to the other, effectively functioning as an array of resistors connected in series. As the resistance pathway is modified by the wiper, the charge in the system is reduced.

Limitations

Although the PTD902-1015K-B504 is a very suitable unit for a range of applications, its performance must be considered within the limitations of its design. These include the fact that the resistance value can only be adjusted between 0 and 10K ohms, and the resistance ladder is limited in width and number of stepped sections, meaning that a very large or precise range of resistance values is not possible. Furthermore, due to its mechanical nature, this unit might suffer from wear and tear over time.

Conclusion

The PTD902-1015K-B504 is a rotary potentiometer, rheostat ideal for a variety of general-purpose applications. It offers excellent accuracy and response time, whilst featuring a low power consumption rating to help conserve energy. This unit has a simple working principle; the user turns the knob to create a resistive path with the help of terminals provided. As the resistance path is increased, the electrical charge is reduced. This unit, however, is limited due to its mechanical nature, and its resistance value can only be adjusted between 0 and 10K ohms.
