Dial potentiometer is also tuning function market more commonly used a potentiometer, we also have many models of dial potentiometer for customers to use in the circuit, today to introduce the dial potentiometer related knowledge, including pulling the dial potentiometer wiring method, pulling the dial potentiometer use precautions, pulling the dial potentiometer how to clean dust and debris, etc. explain the dial potentiometer, I hope to just contact this potentiometer Friends understand more about the dial potentiometer general knowledge.
Pull disk potentiometer wiring method
The plucking disk potentiometer from the left, the first pin for the common terminal, 2, 3 feet for the left and right dual-channel output, 4, 5 for the left and right dual-channel input. The left channel with the wire connected to the left channel, the right channel with the wire connected to the right channel, the ground terminal can be temporarily ignored. Pull the disk potentiometer have line input, line output, and ground terminal, the three points. As for the input corresponds to which output, depending on the plastic knob on the metal contact piece. General PCB substrate signal from left to right direction, the first hole is grounded, the second hole is the left channel output, the third hole is the right channel output, the fourth is the left input, the fifth is the right channel input, the second hole and the fourth hole with wire connection, the third hole and the fifth hole connected to it.
Attention to the use of the plucking disk potentiometer
1. Pull the disk potentiometer in use for a long time, to regularly clean up the potentiometer shaft on some dust and debris, such as not clean, the accumulated dust will affect the output between the lines, there may be in the adjustment will be out of order and other phenomena.
2. For the plucking disk potentiometer pin internal break or resistance body burned, such failure is generally inconvenient to repair, it is recommended to use the replacement components.
3. In the plucking plate potentiometer wiring, each line can not be connected to the wrong, if the wrong connection, it is possible that the output between the lines are incompatible, resulting in the possibility of damage to the potentiometer. So in the wiring should be very careful.
How to clean the dust and debris of the potentiometer pulling disk
1. First of all, use a screwdriver to carefully open the cover of the plucking disk potentiometer fixed card slot, and then remove the potentiometer.
2. Then the dial potentiometer fixed shaft to pull out the shaft, some plucking disk potentiometer can not take out the shaft, this time the potentiometer shaft on some dust and debris, etc., you can directly use the cotton ball with pure alcohol to clean the potentiometer on the shaft.
3. Then after the cleanup is complete, you can apply some lubricating oil or special grease on the shaft, which can delay the potentiometer life.
4. Finally, the dial potentiometer can be reinstalled and fixed.
