A few years ago, due to the negative impact caused by some domestic carbon film type electronic rulers, domestic customers no longer believed in carbon film type electronic rulers, but strongly advocated plastic conductive film type electronic rulers.

The following analyzes the advantages and disadvantages of various carbon films: 1. Let's talk about plastic conductive film first. Plastic conductive film is made by heating and curing thermosetting plastic on a substrate. It is brittle and afraid of falling. Because the thickness of plastic carbon film is thick, it is difficult to repair (this is determined by the characteristics of repair). The main disadvantage is that the friction between plastic conductive film and metal brush will generate static electricity. When static electricity accumulates to a certain extent, it will cause discharge, and output error will definitely occur during discharge, resulting in unstable work. This is its disadvantage. As for how many reciprocating movements will accumulate enough charge to cause discharge, it will vary depending on the humidity of the air in different seasons. Therefore, electronic rulers with plastic conductive film can only be used for rougher machine control, because there will be an abnormal output after every few movements. 2. As for the carbon film electronic ruler, since the carbon film is very thin, it is very easy to repair and can achieve high linear accuracy; and the friction between the metal brush and the carbon film will not generate static electricity, and will not generate discharge, so the output is very stable. Therefore, the carbon film electronic ruler is still the only choice for international brands. The most important thing about the carbon film electronic ruler is the brush technology. Only when the brush and the carbon film are well matched, can we get a product with long life, stable quality, high precision, and no shortcomings of plastic conductive carbon film.

From the perspective of the two, there is no saying that plastic conductive film has advantages over carbon film conductivity.

Whether it is plastic conductive film or carbon film conductive film, the one that suits you is the best!
