PTD901-1015F-B203

Rotary Potentiometers, Rheostats

PTD901-1015F-B203 is a type of rotary potentiometer. Rotary potentiometers are three-terminal variable resistors with wiper contacts that move over a resistive element when the knob is rotated. When the knob is turned, it causes a change in electrical circuit resistance. This change is transmitted to the wiper contact, which allows the connection between the terminal and the resistive element.

Application field

PTD901-1015F-B203 is mainly used in audio level control, audio equalization, and other professional audio equipment to adjust the signal level. It is also used for a variety of industrial control applications, such as controlling the speed of motors and adjusting the light intensity of lamps. Its fine adjustment accuracy and stable performance make it widely used in industrial control.

Working principle

The PTD901-1015F-B203 comprises three terminals and a resistive element connecting them. The rotary action of the knob turns the wiper contact, which is in contact with the resistive element and transmits the change in resistance to the terminals. The three terminals correspond to the end contact, fixed contact and variable contact. The end contact and the variable contact are connected to the resistive element. When the rotary knob is turned, the resistance between the end contact and the fixed contact changes. This change can be transmitted to other electronic components and used to adjust the voltage and current in the circuit.

In summary, PTD901-1015F-B203 is a type of rotary potentiometer mainly used for audio level control and industrial control applications. It consists of three terminals and a resistive element connected between them, and the rotary knob is used to turn the wiper contact and cause a change in resistance, which can be transmitted to other electronic components in the circuit.
