The six-pin potentiometer, as its name suggests, is a potentiometer with six feet. This type of potentiometer has few models, but its application is also extensive. The classification of common adjustable potentiometer models is many, such as 3266 potentiometer product introduction and technical parameters, 3296 precision potentiometer package characteristics are all before contact. We have a hot-selling six-pin potentiometer--Steel potentiometer WH148-2 in Bastet's potentiometers. Here we use the potentiometer WH148-2 as an example to analyze the potentiometer's six-pin potentiometer. What is law?
Iron handle potentiometer WH148-2, material is iron, divided into two kinds of round handle and half handle; at the same time, the hexapod potentiometer WH148-2 is also environmentally friendly and environmentally friendly, of course, the price will be slightly different.

After the above reference drawings and related parameters to understand the six-pin potentiometer connection, it is easier to understand and accept.
Six-pin potentiometer WH148-2 connection method: Although it is six feet, but the wiring head is 3 ports, we call it A, B, C terminal respectively, it is the same as the tripod potentiometer connection, the general circuit has Positive and negative symmetrical power supply, that is, two ports.
1, when the six-pin potentiometer central contact C slides to the potentiometer A end when the output to the ground voltage is +12V, when the potentiometer central contact C slides to the potentiometer B end output to ground voltage is -12V. Single supply control potential, output C has a 0-∞V adjustment range.
2. The audio amplifier is used for the volume control connection. When the six-pin potentiometer center contact C slides to the potentiometer A, the volume is at its maximum. When the six-pin potentiometer center contact C slides to the potentiometer B, the volume is minimum, and the C point is reached. When B has a bad connection, the volume will not die.
