The EBI 1135 absolute inductive rotary encoder serves on servo drives as feedback systems for position and speed control. Its fast EnDat 2.2 pure serial interface is used for transmission of a high-resolution absolute position value to improve transmission reliability, in particular in environments with high electromagnetic noise potential. It distinguishes itself with optimized inductive scanning together with a sturdy design. This becomes possible in particular because it functions without optical components (glass scale, LED), which can be handicapped by contamination, vibration, shock and high temperature.
