Thumbwheel Potentiometers

A thumbwheel potentiometer is a rotary potentiometer with a horizontally-mounted swing arm and a thumbwheel-like knob attached to the arm. The arm and knob turn together, allowing the user to adjust the knob by moving it back and forth. Thumbwheel potentiometers are ideal for applications that require precise and repeatable adjustment of resistance values or voltages.

The 3352T-1-152LF is a thumbwheel potentiometer that offers solid performance and reliability in applications such as audio and instrumentation. This potentiometer features a low profile package and an extended neck for secure mounting. It has a linear taper, meaning that its output is proportional to its input. This makes it suitable for use in automation and process control systems.

The 3352T-1-152LF is a single-turn potentiometer, meaning that it has one rotation cycle. Its rotation cycle is 15.2 mm (0.596 in) and its total deviation is 3.15 mm (0.123 in). Its resistance range is 10 kilohm ± 10%, with a power rating of 0.5 W at 70°C.

The 3352T-1-152LF can be used in a variety of applications such as volume control on audio equipment, adjustable gain amplifiers, security systems, and motor speed control. It is also suitable for use in medical devices, industrial equipment, and consumer electronics.

Working Principle

The working principle of the 3352T-1-152LF is simple and straightforward. The thumbwheel knob on the potentiometer is connected to the arm and shaft. As the knob is turned, the arm and shaft turn together, which causes a change in resistance. This change in resistance is proportional to the amount of rotations, allowing for precise and repeatable adjustment.

The 3352T-1-152LF also has a built-in switch. The switch is actuated by the thumbwheel knob and is used for on/off control of the potentiometer. When the knob is turned off, the switch is open and the potentiometer is inactivated. When the knob is turned on, the switch is closed and the potentiometer is activated.
