Slide Potentiometers

PTL30-19R1-103B2 is a type of slide potentiometer. It consists of a resistive material called a track, that is cut into a specific shape along a line, forming a resistive circuit. The track is sometimes made from graphite or carbon. A single contact, attached to a slider and a moving wiper, travels along this track, making connections and changing the resistance of the circuit.

Application field

Slide potentiometers are widely used in many industries. They are commonly found in stereo systems or automotive, industrial, and other electronic equipment, providing resistance and life expectancy. In audio applications, they can control a variety of sound parameters, including volume and tone, when used in conjunction with preamplifiers and loudness control. In automotive applications, they can be used for speed, acceleration, traction, and variable brake control. Industrial and medical applications may include controlling the speed of transmission, measuring currents, and controlling temperature.

Working Principle

A slide potentiometer consists of three terminals: one that is fixed in place and two that are connected to the slider. The slider is moved along the resistive track by the user, thereby changing the amount of resistance in the circuit. As the slider is moved, the resistance between the two terminals increases or decreases accordingly. The voltage applied at the fixed terminal is divided between the two terminals, providing a voltage signal output that changes as the slider moves. This signal is then used to control the output of the circuit.

The output of the slide potentiometer is directly proportional to the movement of the slider. The movement of the slider causes the resistance to increase or decrease according to the position of the slider, and the output is a voltage that changes to reflect this. As the slider moves across the track, the voltage output increases or decreases accordingly, and this changes the output of the circuit.

The operation of the PTL30-19R1-103B2 is quite simple. It connects three terminals; one that is fixed in place and two that are connected to the movable slider. Moving the slider changes the resistance in the circuit, and as this resistance changes, the voltage output changes accordingly. With this control, users can adjust the output of the circuit depending on their needs.
