Recent absolute, inductive rotary encoder. Called the ECI 119, this encoder sets itself apart with a low profile (height of 19 mm, outside diameter 92 mm) and large through shaft (50, 38, or 30 mm), making it well suited for electric motors in many applications.
One big plus to the ECI 119 is that is is bearingless. As a modular encoder, there is no need to worry about bearing wear or loading, and concerns of mechanical self heating of the encoder and shaft currents are eliminated.
The Heidenhain ECI 119 is a single turn, absolute encoder offering 524,288 (19 bit) positions per revolution, and provides ±90 sec system accuracy. An advantage of the ECI 119 is its bearingless design. As a modular encoder, there is no need to worry about bearing wear or loading, and concerns of mechanical self heating of the encoder and shaft currents are eliminated. If all the mounting tolerances are met, the encoder requires virtually no maintenance outside of contamination protection.
The company’s two types of output are offered: purely serial data (EnDat21) or serial data with 1 Vpp incremental signals (EnDat 01). The SSI interface can also be implemented, but this requires a minimum value order. The EnDat feature lets users transfer incremental and absolute position data along with online diagnostics.
A recent version of Adjusting and Testing Software is available with the ECI 119. The software allows diagnostic checks of the encoder position signals. And the ExI Mounting Wizard allows checking the scanning gap and signal amplitude to assess mounting quality. This ensures reliable and repeatable field mounting.
