Absolute Optical Encoder: Precision Feedback for Modern Motion Control

An absolute optical encoder is a critical component in motion control systems, offering precise feedback on the absolute position of a rotating shaft. Unlike incremental encoders, which measure changes in position, absolute optical encoders provide the exact angular position without requiring movement or a reference point upon power-up. This capability makes them indispensable in applications demanding high accuracy and reliability.

The RZ Series and RZ35 Series absolute optical encoders are advanced solutions designed to meet the diverse needs of modern industries. Combining cutting-edge technology with robust designs, these encoders deliver unmatched performance, precision, and durability for motion control applications.

WWhat is an Absolute Optical Encoder?

Absolute optical encoders determine the exact position of a rotating shaft by using a code disc with unique patterns for each angular position. These patterns are read by optical sensors and converted into digital signals, ensuring accurate feedback even after power loss. This makes them ideal for industries like robotics, CNC machining, and factory automation, where precision and reliability are paramount.
