The potentiometer is a continuously adjustable resistor. When the rotary or sliding handle of the potentiometer is adjusted, the movable contact slides on the resistor body. At this time, at the output end of the potentiometer, an output voltage that has a certain relationship with the external voltage of the potentiometer and the angle or stroke of the movable arm can be obtained.

2. Used as a rheostat

When the potentiometer is used as a current controller, one of the selected current output terminals must be the sliding contact terminal.

3. Used as a current controller

When the potentiometer is used as a rheostat, it should be connected as a two-end device, so that within the stroke range of the potentiometer, a smooth and continuous resistance value can be obtained.

Double potentiometer function

Function 1: The volume of the two channels can be adjusted separately at the same time.

Function 2: Obtain an output voltage that has a certain relationship with the input voltage (external voltage).

Linear potentiometer function 1. Precision potentiometer: used for precision adjustment under small voltage (precision equipment operation panel) 2. Angular displacement potentiometer, linear displacement potentiometer (gyro, Sound System control part)

SMD sliding adjustable potentiometer function

1. The SMD sliding adjustable potentiometer is a continuously adjustable resistor. When its rotary handle or sliding handle is adjusted, the movable contact will slide on the resistor body. At this time, at the output end of the patch slide adjustable potentiometer, an output voltage that has a certain relationship with the external voltage of the potentiometer and the angle or stroke of the movable arm has been obtained. This voltage is the partial pressure of the patch sliding adjustable potentiometer in its process.

2. When used as a rheostat, when the SMD sliding adjustable potentiometer is connected to two ends of the device, a smooth and continuously changing resistance value can be obtained within the stroke range of the potentiometer. At this time, the SMD sliding adjustable potentiometer acts as a rheostat. effect.

3. When one of the selected current output terminals of the slide adjustable potentiometer is a sliding contact terminal, the patch slide adjustable potentiometer can be used as a current controller.
