Where is the difference between the encoder and the adjustable resistance?

We all know that the encoder and the adjustable resistance are belong to the value of a variable electronic components, some friends to think that they are a kind of product, actually otherwise, is there are some differences between them. Encoder and adjustable resistance mainly include the following: the difference between a and encoder multigang, and variable resistor is not; Second, the encoder of the large size, firm structure, long service life; Three different movement operating mode, encoder, the encoder has operation handle; Four, encoder resistance body resistance distribution characteristics and distribution characteristics of the variable resistor, various output function features of the encoder in resistance distribution characteristics are different; Five, the encoder is adjustable range is larger, it is mainly used for circuit ( Voltage or current) Control, general installation on the panel, in order to convenient adjustment. Adjustable resistance adjustable range is small, it is mainly used for compensating circuit parameters, general installation on the circuit board. Shanghai electronic 26 years, specializing in the production of encoder is CLP yuan association member unit, the resistance encoder encoder type, looking for looking for electronic encoder manufacturers.
