Thumbwheel Potentiometers

3352P-1-104LF Application Field and Working Principle

Thumbwheel potentiometers are most commonly used as the input devices in industrial environments. They are a type of variable resistor which allows the user to select a specific resistance based off of a rotatable element. The 3352P-1-104LF thumbwheel potentiometers are commonly used for controlling the voltage, sound, or brightness of a device.The 3352P-1-104LF thumbwheel potentiometers are built using conductive plastic which is an ideal material for applications requiring precise relative motion sensing. This device consists of a stationary element, contact arm, resistive element, and a rotatable element which is the thumbwheel. The mechanism behind the device is that when the thumbwheel is rotated, the contact arm and resistive element move against each other which in-turn changes the resistance value of the device.The 3352P-1-104LF thumbwheel potentiometers have a large electrical rotation angle of 500°. Its low temperature coefficient of resistance and its high linearity is desirable in many applications as it helps reduce errors due to temperature drift. It has a low contact resistance and is protected against electrostatic. The device’s output Rating can either be DC 0 to 10k, 12k, or 15k, dependant on which model you pick.The 3352P-1-104LF thumbwheel potentiometers are suited to a wide variety of industrial applications where precise voltage control is needed. Typical applications include audio volume control, medical equipment, audio power gain control, rotary encoders, instrumentation, and gaming machinery. The device is also suited to environments which require high-shock or vibration resistance; such as those found in robotics, aerospace engineering, or military applications.Overall, the 3352P-1-104LF thumbwheel potentiometers are a reliable and precise device choice for applications needing a fine control of voltage. The devices high linearity and low resistance temperature coefficient makes it a popular choice among engineers looking to reduce errors due to temperature drift. The device’s polyamide housing makes it more resistant to shock, molding, dust, and short circuits. Additionally, a wide number of models are available with resistance levels ranging from 0 to 10k, 12k, and 15k. As a result, the 3352P-1-104LF thumbwheel potentiometers can be used in a variety of industrial applications.
