Tag: encoder

The encoder can convert the mechanical geometric displacement on the output shaft into pulse or digital quantity. This is the most widely used sensor at present. Since the photoelectric encoder is coaxial with the motor, when the motor rotates, the encoder (grating plate) rotates at the same speed as the motor, reflecting the current speed of the motor. It is mainly composed of four parts: light source, code disc, optical system and circuit. Then we will explain according to different kinds of encoders.

Absolute rotary encoders have been more and more widely used in angle, length measurement and positioning control in various industrial systems because each position is absolutely unique, anti-interference, and has no power-off memory. There are many engraved lines on the absolute encoder optical disc, and each engraved line is arranged in sequence with 2 lines, 4 lines, 8 lines, 16 lines...

An encoder is a device that compiles and converts a signal (such as bit-stream) or data into a signal form that can be used for communication, transmission and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code wheel, and the latter is called a code ruler.
