potentiometer is used, such as poly carbonate resin made of synthetic resin, etc., of the stent potentiometer, terminal, shell and other materials are iron
Quality materials such as electroplating and then press into and potentiometer brush is made of foreign copper-nickel alloy, which would give rise to parts such as oxidation or rust, so electric
Digital devices do not contain ammonia, amines, alkali solution and aromatic hydrocarbons, ketones, halogenated hydrocarbons, such as large concentrations of chemicals in the environment
Use of potentiometers can not afford to let more exposed to the environment. To extend the life of potentiometers.
potentiometer on the long-term to contain ammonia, amines, alkali solution and aromatic hydrocarbons, ketones, halogenated hydrocarbons, chemicals, etc.
The concentration of a large environment, carbon film film will be oxidized, it will cause noise or invalid potentiometer or the voices of change there is no law. Shell terminal, such as stent
Rust, caused by noise, such as potentiometers. Brush if rust will cause noise and synchronization Potentiometers bad and so on.
