Absolute Encoders(Single-Turn)

◆About Absolute encoder
Absolute encoders output the absolute value of rotation angles.The encoders are used for position control of servo motors mounted on machine tools or robots. As shown in Figure 2, rotation slits are lined from the center on concentric circles. Slits indicates binary code strings of 2 pulses/rev from the center.Multi-turn absolute encoders memorize the rotation quantity data over one rotation.
