Potentiometer classification and model

The following is the circuit diagram of Classifier and Model of Potentiometer. A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. It is widely used in electronic circuits for controlling signals, adjusting volume, brightness, and other parameters.

1. Classification by Resistor Body Material:

• Wirewound Potentiometer: The resistor body is made by winding a wire around a metal or non-metal plate coated with an insulating material. This type includes general-purpose, precision, high-power, and pre-calibrated versions, often denoted by the model number WX.
• Non-Wirewound Potentiometer: These are further divided into solid and membrane types.

2. Solid Potentiometer: This category includes:

• Organic Synthesis (WS)
• Inorganic Synthesis (WN)
• Conductive Plastic (WD)

3. Membrane Potentiometer: This type includes:

• Carbon Film (WT)
• Metal Film (WJ)

4. Classification by Adjustment Method:

• Rotary Type
• Push-Pull Type
• Linear Slide Type

5. Classification by Resistance Change Rule:

• Linear Type
• Logarithmic Type
• Exponential (Index) Type

6. Classification by Structural Characteristics:

• Single Turn, Multi-Turn
• Single Joint, Double Joint, Multiple Joints
• Tap Type, With Switch, Locking, Non-Locking, Surface Mount

7. Classification by Driving Mode:

• Manual Adjustment
• Electric Adjustment

8. Other Classification Methods:

• Standard
• Magnetic Sensitive
• Photo-sensitive
• Electronic
• Step Potentiometer

Understanding these classifications helps engineers and designers choose the right type of potentiometer based on their application requirements, such as power handling, accuracy, environmental conditions, and ease of use. Whether it's for audio control, sensor calibration, or industrial automation, selecting the correct potentiometer is essential for optimal performance.
