The ERO 6000 angle encoder is suited to use in metrology systems, compact rotary tables and high dynamic applications, such as air bearing spindles, laser trackers and robot arms. Compact scanning is made possible by the application of a divergent scanning principle that does not require lenses or other beam-directing optics. A signal error compensation function is integrated in the encoder's scanning sensor, which compensates the amplitude size and amplitude ratio within certain limits, and thus increases the reliability and safety margin of the device.
