ERO 1470 Rotary Encoder Specs

The document summarizes the specifications of the ERO 1470 rotary encoder from HEIDENHAIN, which is designed for integration in motors and features integrated interpolation electronics and a miniature size. Key specifications include an incremental encoder with 1000 line counts, 5000 signal periods per revolution, and a system accuracy of 1000: ±130'' or 1500: ±114''. It has a blind hollow shaft, operates from -10 to 70 degrees Celsius, and provides IP66 protection at the housing.
