Thumbwheel Potentiometers

The 3352V-1-203LF thumbwheel potentiometer is a user-adjustable resistor with a rotating wheel or a slider that can be used to adjust the resistance. It is also known as a thumbwheel encoder and is typically used in the industrial and commercial control systems and automation sectors.

Application Field

The thumbwheel potentiometers are usually used in the industrial control systems and automation industry due to their high precision. They are used in motor speed controllers, industrial temperature controllers, and other commercial and industrial settings. The 3352V-1-203LF model is specially designed to be used in precision instruments and digital controls where accuracy and reliability are paramount. It is also designed for the extreme environmental requirements of the medical and aeronautical sectors.

Working Principle

The 3352V-1-203LF operates by means of a two-pole design. The rotating wheel or sliding element is connected to two wiper contacts that contact a resistance track. As the wheel is rotated, the wiper contacts slide along the resistive track, adjusting the resistance and providing an analog voltage signal. The 3352V-1-203LF is designed to accurately measure the resistance in a wide range of environments and electrical conditions.

The resistance of the 3352V-1-203LF is accurate to within +/- 0.3% across the full rotation of the wheel or slider. It is designed to operate in temperatures ranging from -20 to +85 C and in humidity levels of 95% RH, without affecting its performance. The body is designed to be resistant to both shocks and vibrations, making it ideal for industrial use.

Conclusion

The 3352V-1-203LF thumbwheel potentiometer is a precision instrument designed for use in the industrial and commercial control systems and automation industry. It is designed to provide precise and reliable operation in extreme environments, such as those encountered in the medical and aeronautical sectors. Its two-pole design allows for accurate resistive tracking, and the resistive accuracy is within +/- 0.3% across the full rotation of the wheel or slider.
