What’s the Difference Between Absolute and Incremental Encoders?

Rotary encoders connect to a shaft and, as the shaft rotates, the encoder outputs pulses. These are used to determine the speed of the object. By counting the amount of pulses per one full turn of the ...

The Right Encoder Can Reduce Downtime

Every encoder-based motion-control axis, such as a servo motor or step motor, must know where it is to be accurate. If it doesn’t, it will never reach its target position. But the encoder must first ...
