Rotary Potentiometers, Rheostats, are broadly defined as electrical components primarily used to modify electrical signals by variably and continuously modifying the resistance in a circuit. The 132B00502 is no exception and is a single-turn, conductive plastic rotary potentiometer with a wide range of electrical and performance capabilities. This article will explore the application fields and general working principle of this device.

The 132B00502 rotary potentiometer is a versatile electrical component ideal for a range of applications due to its high-level reliability and wide range of adjustable resistance levels. Some of the common applications of this device include volume control, power supply systems, lighting systems, temperature control, and motor speed adjustment. For example, in communications systems, it is used to regulate the audio volume levels. In motor systems, it is used to control the speed when coupled with speed control unit.

The working principle of the 132B00502 is based on the concept of a wiper sliding on a resistive track. The resistance is modified by the movement of the wiper which translates into a variation of the electrical or analogue output. The device is usually composed of a resistive element, a wiper, and two terminals. The resistive element is the resistive track onto which the wiper slides, providing a variable resistance between the two terminals. As the rotary or linear potentiometer is turned or moved by the user, the wiper slides along the resistive track and the resistance between the two terminals is changed. The overall resistance of the potentiometer is calculated by summing the resistance of the track and the resistance between the terminal and the wiper.

The benefit of the 132B00502 rotary potentiometer over its counterparts is its high-level reliability and adjustable resistance range. It is capable of operating over a wide temperature range, from -40°C to +85°C, and withstanding day-to-day wear and tear, making it an ideal choice for high reliability applications. Additionally, the device is capable of providing a linear resistance range of up to 100 kΩ, making it suitable for applications that require adjustable resistance levels.

The 132B00502 rotary potentiometer is a versatile electrical component that can be used to variably and continuously modify electrical signals in a range of applications. Its high-level reliability and adjustable resistance range make it ideal for use in a wide range of systems, such as communications, power supply, lighting, temperature control, and motor speed adjustment. Its working principle is based on the wiper sliding along a resistive track, changing the resistance between the two terminals as it moves. The design of the device ensures that it operates over a wide temperature range and is capable of withstanding day-to-day wear and tear. For these reasons, it is a popular choice for high reliability applications.
