Heidenhain’s ECI 119 absolute, inductive rotary encoder features a low profile (height of 19 mm, outside diameter 92 mm) and large through shaft (50, 38, or 30 mm), making it suited for electric motors in applications including general automation, electronics, robotics, plastic injection molding machines, and on swivel and tilting axes. Expanding on the established ExI 13xx and ExI 11xx series, the encoder is a single-turn, absolute encoder offering 524288 (19 bit) positions per revolution and providing ±90” system accuracy. The modular system’s bearingless design eliminates worry about bearing wear, loading, and mechanical self heating of encoder and shaft currents. The device uses the EnDat serial data interface, which allows users to transfer incremental and absolute position data, as well as perform online diagnostics.
