Pepperl + Fuchs encoder

Incremental encoders provide a fixed number of pulses per revolution, and the speed is calculated by the number of pulses measured per unit time. In order to measure the angle and position, it is usually counted from a starting reference point. The dual-channel output encoder has two signals with a phase difference of 90 degrees. This allows the controller to determine the direction of rotation and realize the function of bidirectional position measurement. In addition, the three-channel incremental encoder has a third signal channel (that is, the "0" channel, or the reference channel), and there is only one pulse output per revolution.
