Rotary Potentiometers, Rheostats

PTD901-1025K-B203 is a rotary potentiometer designed to control the amount of electrical current allowed to flow through it at a given time. This type of electrical component is often referred to as a variable resistor, because it is able to regulate the amount of electrical current passing through it in a manner comparable to a resistor. PTD901-1025K-B203 can also be referred to as a "rheostat".

Application Field

The PTD901-1025K-B203 rotary potentiometer is commonly used in a broad range of applications. It is often used in audio and electronic circuits to make fine adjustments to the levels of amplification and volume. It can also be used to adjust the brightness of a light bulb or the speed of a motor. Additionally, it can be used to control the temperature of an oven or to regulate the flow of liquid through a system.

PTD901-1025K-B203 can also be used in medical and laboratory equipment to adjust the voltage and current supplied to various instruments. This makes it possible to accurately control the reactions of complex chemical and biological samples. It is also often used in automotive and machine control systems, where it is used to regulate the amount of fuel, air, and other elements supplied to the engine.

Working Principle

PTD901-1025K-B203 is composed of three main components: a stationary terminal, a moving terminal, and a rotary body. The stationary terminal is usually connected to the power source, while the moving terminal is connected to the load. The rotary body is a shaft which is connected to a resistive element. As the shaft is rotated, the resistance of the element changes, resulting in a change in the amount of current flowing through the circuit.

PTD901-1025K-B203 is designed so that the amount of current flowing through the circuit can be finely adjusted. The resistive element is designed with a wiper that can be finely adjusted as the shaft is rotated. This allows for precise control over the amount of current flowing through the circuit.

The PTD901-1025K-B203 rotary potentiometer is a versatile and reliable electrical component. Its simple design and ability to fine-tune the amount of current passing through it make it ideal for a wide range of applications. It is a popular choice for audio and electronic circuits, medical and laboratory equipment, automotive and machine control systems, and other applications requiring precise control over the amount of current passing through the circuit.
