3352E-1-204 Application Field

The type 3352E-1-204 thumbwheel potentiometer from Spectrol is a popular choice for position sensing applications. This device is used in many applications such as automotive, industrial automation, or medical equipment that require accurate measurement of position. Even the most demanding use cases require reliable position sensing.

Working Principle

The 3352E-1-204 thumbwheel potentiometer features an integrated spiral-wound element and mechanical switch. The device is constructed using a custom shaped conductive wiper element and a three-wire composition. This design allows for accurate positioning and sealing of the device to prevent any leakage of vapor and dust. The mechanical switch that is integrated into the device acts as a failsafe indicator, alerting the user when the device is in an incorrect position.

As the user rotates the thumbwheel, the movement of the connected wiper element changes the electrical resistance between the leads. This effectively allows for a direct correlation between the position of the knob and the device output. The output is a linear voltage that is equal to the ratio of the angle of rotation over the full range of the potentiometer.

The 3352E-1-204 is rated for over one million rotations and has a potentiometer resistance range of 100 ohms. It is designed to optimize performance in a variety of environmental conditions including temperature, humidity, and vibration. The device is certified to IP67 standards, making it water and dust resistant.

Summary

The 3352E-1-204 thumbwheel potentiometer from Spectrol is a great choice for any position sensing application. It offers an improved mechanical switch, increased rotational life, and a reduced potentiometer resistance range compared to other devices. Furthermore, the device is IP67 rated, ensuring it is protected against water and dust. This device is an ideal choice for applications where precision and reliability are paramount.
