What is the difference between contact encoder and non-contact encoders?
Encoder is variable resistor, the role of the encoder in circuit is obtained with the input voltage (
Into a certain relationship between the output voltage, so called the encoder.
Encoder according to the contact and non-contact encoders can be divided into contact encoder.
Contact the encoder with non-contact encoders both has also exist certain difference.
Below we see contact the difference between the encoder and non-contact encoders.
Contact the difference between the encoder and non-contact encoders: a contact, contact encoder encoder is brush contact resistance and mechanical contact directly, in order to realize the electric connection between the two, to obtain the output voltage of the encoder.
Including the line around the encoder and the line around the vast majority of encoder.
And, can be rotating or sliding straight type, as well as the linear and nonlinear and so on.
Second, non-contact encoders non-contact encoders are 'contact is surrounded with resistance body do not make direct mechanical contact, but in other ways (
Such as beam or light irradiation)
Realize the electric connection between the two, to obtain the output voltage of the encoder.
Such as photoelectric encoder.
Now is only lines around the class, it can be rotating or sliding straight type, as well as the linear and nonlinear.
Shanghai electronic products specializing in the production of encoder for 26 years, the main product of encoder for contact encoder, encoder type rotary encoder, straight and smooth encoder, the motor encoder, rocker encoder, switch, encoders, etc. , the encoder model is complete, an industry first, find the encoder manufacturers are looking for electronics.
