Rotary Potentiometers, Rheostats are commonly used components in a wide variety of mechanical and electrical machines. The PTD901-1215F-B103 is one such product, which is applied as a voltage or current control component in many machines. This article will discuss the application field and working principle of PTD901-1215F-B103.

The PTD901-1215F-B103 is a rotary potentiometer, containing a shaft that rotates against a resistive element. It is suitable for use in areas with tight spaces in industrial control systems and other instruments. The product is RoHS-compliant and has an operating temperature range between -5 and 75°C.

The PTD901-1215F-B103 is mainly used to adjust and monitor the operation of alternating current devices and circuits. It acts as a two-wired resistance potentiometer, with one end connected to the adjustable positive voltage and the other end connected to the adjustable negative voltage. The variable resistance of the product can be adjusted with a thumb wheel on the shaft and is used to regulate the electric current flowing through the circuit. This enables the user to control the output of the current, allowing fine adjustments to be made.

The PTD901-1215F-B103 is also applicable to the control of DC motors. It is used to control the speed of the motor by altering the amount of current travelling through it. The shaft rotates in the opposite direction to the current, thus controlling the speed of the motor. In addition, it can also be used to control the direction of the current, allowing the device to be used for forward and reverse motor control.

The working principle of the PTD901-1215F-B103 is based on the triboelectric effect, in which a rotating conductive surface causes an electric charge to be induced in the resistive element. As the shaft rotates, the electric charge builds up along the tracks on the resistive element and is transferred to the output terminals, thus providing a variable resistance in the circuit. Depending on the angle of rotation, the resistive element will provide a higher resistance or a lower resistance, which can be used to control the output of the circuit.

The PTD901-1215F-B103 is a versatile component as it can be used in a variety of applications including voltage and current control as well as DC motor speed and direction control. Its simple and robust design makes it suitable for a variety of applications and its triboelectric effect-based working principle enables it to provide reliable control of circuits.
