Slide Potentiometers are essentially variable resistors whose resistance is directly dependent on the position of a sliding element along a resistive material. PTL45-10R0-104B2 is a type of slide potentiometer whose application field and working principle will be discussed in this paper.

PTL45-10R0-104B2 is a high-precision slide potentiometer, whose resistance range is 10kΩ ±20%. It is made up of resistive strip, wiper, central spindle and mounting portion. This product is specially designed to feature special wiring, installation and performance.

The application field of this type of slide potentiometer is quite extensive. It can be used as a linear motion sensor in equipment like LCD screed, laptop touchpad and game controllers. It can also be used to measure position and rotation angle in motors, robots, aircraft instrument systems and so on. In addition, it can be used for various adjustable circuits such as sound volume controls, microphone preamplifiers, and AD and DA conversion system.

The working principle of this slide potentiometer is based on the law of proportion. The central spindle of this device has a conductive strip attached to one end and a wiper bar at the other. When the spindle rotates, the wiper bar slides and contacts the resistive strip, which changes the resistance along the path of the sliding wiper bar. As the wiper bar slides across the 40 mm length of the resistive strip, it changes the resistance between 0 ohms (minimum end) and 10K ohms (maximum end). Therefore, the resistance is proportional to the amount of the sliding element and will generate a voltage signal or resistance value that can be used to drive a certain device.

In conclusion, PTL45-10R0-104B2 is a type of slide potentiometer with a wide application field and simple working principle. It is a multi-function device, which has already been widely used in various industries like electronics, medical, aerospace and so on.
