Dynapar A125 Encoder With Interbus Interface

Acuro Series AI25 Absolute Encoder with Interbus Interface

Up to 17 Bit single-turn resolution

4096 revolutions of multi-turn resolution

Short installation depth

Safety through self-diagnostics

Solid shaft and hollow shaft versions

-40C to +100°C Operating temperature

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.
