Thumbwheel Potentiometers

The 3352T-1-301LF by Bourns is a digital thumbwheel potentiometer used for providing a variable resistance. It offers high taper accuracy, long life and low power consumption. It is designed for the application in digital signal processing and lighting control systems. A thumbwheel potentiometer can be used for many applications including motor speed, temperature and voltage control.

The 3352T-1-301LF has a wide operating range typified by a linear rotary motion, adjustable resistance range of 10 to 90%, and an adjustable travel of up to +/- 30°. It is well-suited to the increasingly popular and sophisticated field of digital control as well as in any form of application where a precise and reliable variable voltage or resistance is desired.

Working Principle

A thumbwheel potentiometer works by exerting control over an electrical circuit via a manually operated rotary switch. The knob is rotated, allowing an internal wiper to move along a resistance element, increasing or decreasing resistance. The movement of the wiper changes the current that runs through the potentiometer, which in turn adjusts the voltage or resistance of the electrical circuit.

The thumbwheel potentiometer offers significant advantages due to its simple design. The design allows for an adjustable resistance range of 10-90%, a relatively small size, low power consumption, long life expectancy, and precise taper accuracy. Additionally, the 3352T-1-301LF is designed for use in digital signal processing and lighting control systems and is a great choice for applications where an adjustable voltage, current or resistance is desired.

Applications

The 3352T-1-301LF is specifically designed for use in applications where an adjustable variable resistance or voltage is desired. It can be used to adjust the speed and direction of motors, voltage control, temperature control, and many other applications. Its low power consumption and long life expectancy make it ideal for use in a variety of applications including digital signal processing and lighting control systems.

It is also suitable for other applications such as audio equipment, VFD displays, and analytical instrumentation.
