The development history of adjustable potentiometer

The so-called adjustable potentiometer is a rheostat that can change the resistance value by external force. How much the resistance value changes, how fast the resistance value changes, the accuracy of the resistance value change, and how many ohms the total resistance value is, these parameters all depend on the level of the adjustable potentiometer. At present, our country's self-produced adjustable potentiometer can be said to have achieved earth-shaking changes.

  Why do you say that there have been earth-shaking changes? The potentiometer product is actually very simple. A few people can produce it, 200 people can produce it, but if there is no problem in producing the potentiometer product, and the quality has always been stable, it depends on whether the potentiometer manufacturer has the ability to introduce new ones. And perfect management process. The development of potentiometers in our country has improved to a certain level. Analyzed from the structure of the potentiometer; the key components of the potentiometer are composed of a shaft, a shaft sleeve, a shell, a moving piece, a brush, a carbon piece, and a terminal.

   The shaft, sleeve, shell, and terminal are all metal stamping materials, and the moving piece is plastic. There is no need to worry about this. There is no problem in our country, and Japan and Germany are currently the same. The key is that the components are the brush and the carbon sheet. The material usage level of the brush and whether the carbon sheet printing is in place is related to whether the potentiometer is high-end.

   Potentiometer brushes currently use phosphor copper, beryllium copper, and nickel silver. At the high end, beryllium copper is generally used. There are more high-end brushes that use alloy wires, which are very expensive. The carbon sheet is relatively more important, because the printing of the carbon layer and the silver layer on the surface of the carbon sheet and the diameter of the material affect the quality of the potentiometer. Of course, it also has a certain impact on production control and production environment. The key is that the level of materials and printing technology has a direct impact. At present, many users in the market require resistance symmetry.
