Rotary Potentiometers, Rheostats

A rotary potentiometer is an electronically controlled variable resistor used to adjust the voltage and current in a circuit. The resistance can be changed by simply turning the knob of the potentiometer. The resistance can also be varied by rotating the wiper shaft, which is linked to the knob. This type of variable resistor is most commonly used for volume and tone controls on the popular electric guitars.

The 450T328S502A1C1 rotary potentiometer is a precision device designed for measuring output potential in power electronic applications. It has a stainless steel construction, and is highly reliable. It features a single-turn rotary design and a max resistance of 155 ohm.

Application Field

The 450T328S502A1C1 rotary potentiometer is used primarily in audio, video, telecom, automotive, and computer applications. It is widely used in audio amplifier systems, for adjustment of sound levels, as well as in video recording and editing systems. The potentiometer is also used in the modem industry, where it is used to control optical signal amplifications and converters for the transmission and reception of data. In automotive applications, it is used for controlling the fuel management system.

Working Principle

The 450T328S502A1C1 rotary potentiometer works on the principle of resistive splitting. It consists of three terminals, namely a common terminal (C-Terminal), a variable terminal (V-Terminal) and a wiper terminal (W-Terminal). The C-terminal is connected to the power source, while the W-Terminal is connected to the load. As the knob or the shaft is rotated, the resistance between the W-Terminal and the V-Terminal is varied, thus regulating the amount of current that flows through the circuit.

The 450T328S502A1C1 rotary potentiometer is a highly reliable and accurate device, with single-turn accuracy to 0.5%. It is small in size, making it suitable for use in confined spaces. The device is rated to withstand temperatures up to +125°C, and provides excellent noise and vibration immunity. The 450T328S502A1C1 rotary potentiometer can be used in a wide variety of applications, thanks to its versatile design and high precision.
