Applications

The 3352T-1-104LF is asked for in many control space applications where a small form factor potentiometer is needed. It is commonly used in medical devices for diagnostics applications, and other industrial equipment such as servo motors, CNC systems, actuation systems, etc. Additionally, it may be used in robotic research projects.

Working Principle

The working principle of the 3352T-1-104LF is based on the linear voltage divider effect. The resistance of the wipers arm is increased or decreased with its movement from one terminal to the other. The wipers arm is connected to the thumbwheel, thus turning the knob controls the voltage output of the more distant part of the divider.

To understand how the 3352T-1-104LF works, we must first understand the basics of a voltage divider. In a voltage divider circuit, the voltage across any resistor is a direct reflection of the resistance of that resistor and inversely proportional to its value. Thus, if one resistor has a high resistance and the other has a low resistance, the high resistance resistor will have a high voltage across it and the low resistance resistor will have a low voltage across it.

The 3352T-1-104LF works in a similar manner. As you turn the knob, the resistance of the wiper arm is increased or decreased. Because the voltage across each terminal is inversely proportional to its resistance, and the wiper is connected to the thumbwheel, the voltage output of the more distant part of the divider is controlled by the knob.

Conclusion

The 3352T-1-104LF is a miniature thumbwheel potentiometer that is well-suited for applications including volume control or other applications that require a fine adjustment. It is a reliable choice for applications that require a small form factor potentiometer, including medical diagnostic equipment, servo motors, CNC systems, and actuation systems. The working principle of the 3352T-1-104LF is based on the linear voltage divider effect, with the resistance of the wipers arm being increased or decreased with its movement from one terminal to the other.
