Thumbwheel Potentiometers

Thumbwheel potentiometers are rotary potentiometers with a thumbwheel. These potentiometers are designed for use in applications requiring the user to make adjustments and to be easily accessible as they are often used with an integrated thumbwheel on the device itself. The most common type of thumbwheel potentiometer is the single-turn type, which consists of a resistive element with a variable position thumbwheel.

The 3352V-1-200LF is a single-turn thumbwheel potentiometer that features an anodized electrolytic aluminum construction and a plastic thumbwheel. This potentiometer also features an A/C switch, which allows the user to switch between two resistances (A or C), allowing a greater range of adjustment. The resistive element of this potentiometer is made of a conductive carbon-filled film, which offers resistance values between 200Ω to 5,000Ω and tolerance ranges of +2% to -10%.

Application Field

The 3352V-1-200LF thumbwheel potentiometer is primarily used in applications requiring precise adjustment of equipment such as amplifiers, lighting, and music instruments. It is also used in automotive electronics, industrial automation, and medical instrumentation. The application fields of this thumbwheel potentiometers range from audio, video, security, IT, communications, and human-machine interfaces.

Working Principle:

The working principle of a 3352V-1-200LF thumbwheel potentiometer is based on the electric charge. The resistance is electrically charged between two terminals, and the adjustable thumbwheel is connected to a wiper terminal which produces a variable resistance value. When the thumbwheel is rotated, the position of the wiper changes to adjust the resistance between the two terminals, thus producing a variable voltage. The voltage can then be used to adjust the output of the device or to control the current output.

This thumbwheel potentiometer is designed for panel mount applications and features a mounting system that is durable and secure. It can withstand the vibrations and shocks encountered in most applications and is designed to last for several years.

The 3352V-1-200LF thumbwheel potentiometer is an excellent choice for applications requiring the user to make frequent adjustments. Its adjustable resistance and robust design make this potentiometer a reliable and versatile component.
