PRODUCTION DESCRPTION

working principle

When a voltage is applied between the two fixed electric shocks of the resistor body, the position of the contact on the resistor body is changed by a rotating or sliding system, and a fixed contact position can be obtained between the moving contact and the fixed contact. relationship voltage. It is mostly used as a voltage divider, which is that the potentiometer is a four-terminal element. Potentiometers are basically sliding rheostats. There are several styles. They are generally used in speaker volume switches and laser head power adjustment. Potentiometers are an adjustable electronic component. It consists of a resistive body and a rotating or sliding system. When a voltage is applied between the two fixed electric shocks of the resistor body, the position of the contact on the resistor body is changed by a rotating or sliding system, and between the movable contact and the fixed contact, a position that is consistent with the position of the movable contact can be obtained. voltage of a certain relationship.

Naming and labeling method

(1) The naming rules of potentiometers are the same as those of resistors, except that they start with the letter W.

(2) Potentiometer labeling method: Potentiometers generally use the direct labeling method, and letters and numbers are used on the potentiometer shell to mark their model, nominal power, resistance value, and the relationship between resistance value and rotation angle, etc. For example: WT-Ⅱ-1-1k-X potentiometer is expressed as a single carbon film potentiometer type II, the power is 1W, the resistance value is 1kΩ, and the curve is linear.

Wiring method

For potentiometers (or trimmer resistors, etc.) regular pins (for example, a potentiometer with 3 pins), the resistance value at both ends is fixed, and the resistance value of the middle pin to either end pin is variable;

It is equivalent to dividing the potentiometer into two series resistors from the middle pin, and the total series resistance value is fixed;

Therefore, if it is used as a variable voltage divider resistor, one end is connected to the input voltage, the middle end is connected to the output, and the remaining end is grounded;

If it is used as a variable resistor, one end is connected to the input voltage, the middle end is connected to the output, and the rest can be left floating or connected to the middle end.
