How to use six-pin double potentiometer2021

Potentiometers are often used in circuits. There are often single potentiometers and double potentiometers. Single potentiometer refers to a single channel with only one resistor body. A more commonly used potentiometer whose axis is only Control a group of potentiometers. The dual potentiometer refers to a dual-channel, two potentiometers are installed on the same shaft, when the shaft is adjusted, the contacts of the two potentiometers rotate at the same time. Single potentiometers generally consist of only three pins, while for dual potentiometers, there are generally 6 pins, 8 pins or more.

Today I will tell you about the wiring method of the six-pin double potentiometer, the method of repairing the bad contact failure of the double potentiometer, and the precautions for the use of the six-pin double potentiometer.

Six-pin double potentiometer wiring method

At present, the 3-pin single potentiometer is generally used as a single channel to adjust the volume. The wiring is generally grounded at pin 1, then pin 2 (that is, the middle pin) is connected to the output terminal, and pin 3 is connected to the output terminal. Then the 6-pin dual potentiometer is generally used for dual-channel volume adjustment. In fact, the wiring is roughly the same as the wiring principle of the 3-pin single potentiometer. First, the 1 and 4 pins of the six-pin double potentiometer are connected to the ground at the same time. For the 2 pin, it is connected to the left channel output, and the 3 pin is Connect pin 5 to the left channel input, pin 5 to the right channel output, and pin 6 to the right channel input. So everyone should distinguish clearly between the single-connection and double-connection potentiometer wiring methods.

Double potentiometer repair bad contact failure method

After using the double potentiometer for a long time, some phenomena such as poor contact will often occur. For example, when the potentiometer is adjusted and rotated, there will be some troubles such as rotating noise. For this fault handling method, you can first add some appropriate lubricant to the potentiometer shaft, and then take a few more times to eliminate the rotating noise. Also, after the potentiometer has been used for a long time, some dust will accumulate in the potentiometer, and it will also cause troubles such as rotating noise on the adjustment and rotation of the potentiometer. In dealing with this kind of failure method, you must first open the double potentiometer carefully, and then use some small brush Clean the dust on the pins of the upper and lower connected potentiometers. After cleaning, install the potentiometer back. The rotating noise of the potentiometer will be eliminated at the same time after the repair.

Precautions for the use of six-pin double potentiometer

1. On the wiring of the six-pin double potentiometer, do not connect the wiring between the pins incorrectly, otherwise the use of the previous potentiometer may cause some adjustment failures, and the second is that it may be easy to use. The potentiometer is damaged. Therefore, when operating the potentiometer wiring, pay special attention to the wiring.

2. When adjusting the rotation of the double potentiometer, do not use too much force to rotate it. Otherwise, the shaft inside the potentiometer will be loosened, which may cause the adjustment of the potentiometer or adjust it all at once. It is very small, or it can be adjusted to a large amount all at once.

3. In the installation of the double potentiometer, do not pull too much on the connection of each pin, otherwise it is easy to fall off the pin from the insulating panel of the potentiometer. Therefore, more attention should be paid to all aspects of the installation of the potentiometer.

4. Regarding the use of double potentiometers that can replace single potentiometers, it is possible in principle, but when replacing, please ask the relevant technicians to operate and install, so as not to make mistakes when wiring. Wire, which will easily damage the potentiometer.
