Overview / Design Principle:
The ACURO AI25 optical absolute industrial encoder
is available in a single-turn or multi-turn version.
The multi-turn design is based on a reliable high-speed
gear with optical scanning and the latest generation
of OptoASIC technology.
The mechanical concept is based on a double ball bearing
design, which is available as a solid-shaft or hollow-shaft
version in common shaft diameters.
