Top quality optical encoders rotary  

Top quality optical encoders rotary By calculating the number of output pulses per second of photoelectric encoder, the current motor speed can be reflected. In addition, in order to judge the direction of rotation, the encoder can also provide two optical code outputs with phase difference of 90 ° to determine the direction of rotation of the motor according to the state change of the two optical codes. Generally, the detection accuracy of photoelectric encoder is relatively high, but it needs higher protection requirements when it is used in outdoor and harsh environment, and it is not suitable for use in condensation envir…
