Working Principle

The PTV09A-2020F-A104 acts as an adjustable resistor, or rheostat, whose resistance varies depending on the position of the shaft. The device consists of a coil of enclosed wire, with an adjustable contact or wiper attached to the rotor that moves along the coil when the shaft is turned. When the contacts slide along the resistor’s track, they make an electrical contact with different parts of the coil, thereby changing the resistance of the resistor.

The resistance of the resistor increases or decreases in proportion to the angle between the wiper and the start of the track. When the wiper is turned clockwise, the resistance increases, and when it is turned counterclockwise, the resistance decreases. This makes it ideal for applications in which the output must vary according to the angle of the shaft, such as radio and television receivers.

PTV09A-2020F-A104 is a versatile device that offers adjustable resistance in a wide range of applications. It is a convenient and cost effective way to control and adjust the voltage or current in a circuit, making it an essential component in a variety of electronic and electrical projects.
