The 3345W-1-502T series of thumbwheel potentiometers is commonly used in automotive, industrial, security, air-conditioning, HVAC, and other electronic fields. In a typical application, it allows the user to easily adjust the electrical signal from a given device such as a thermostat to a certain degree or other value, without relying on an external, expensive component or device.

The 3345W-1-502T series of thumbwheel potentiometers is popular in many automotive fields where it is used to adjust a variety of parameters such as throttle position or automatic transmission shift points. Automotive technicians can easily calibrate and adjust the throttle position with the help of the 3345W-1-502T series of thumbwheel potentiometers.

It is also frequently used in industrial sectors to adjust parameters like flow, temperature, velocity, power, or pressure. Industrial engineers can quickly and easily adjust settings of valves, pumps, and other components with the help of the 3345W-1-502T series of thumbwheel potentiometers.

A 3345W-1-502T series thumbwheel potentiometer can also be used in air-conditioning and HVAC systems, providing an easy-to-understand interface for users to adjust the voltage, current, and other settings of their air-conditioning and HVAC systems.

Working Principle

The 3345W-1-502T series of thumbwheel potentiometers are designed to detect and adjust the electrical signal to a certain calibration point, in a range from 0 to 5Vdc. The potentiometer has a linear characteristic, meaning that the output signal will be proportional to the rotation angle of the knob.

The thumbwheel potentiometers are equipped with an integrated screw-threaded fixing piece, allowing them to be securely mounted to a device or panel. The potentiometer is constructed of an injection molded plastic casing and an O-ring for moisture protection. It utilizes a molded shaft with plastic bushings to provide smooth control and has an operating temperature range of -20°C to +85°C.

The 3345W-1-502T series of thumbwheel potentiometers are typically used with three or four terminals, depending on the models and application requirements. The main terminals are labeled with a ’+’ and ’-’ sign, usually indicating the input and output of the electric circuit, while the additional terminals are used for sense or other control purposes.

The 3345W-1-502T series of thumbwheel potentiometers are highly reliable and are designed to withstand vibration and shock, which makes them suitable for use in industrial, automotive, and other harsh environments. They are also easily adjustable, making them the ideal choice for users needing to make quick and accurate adjustments to their devices.
