APPLICATION/INDUSTRY
The Dynapar brand ACURO Absolute Encoder
offers a modern full-feature design equipped
with Profibus interface.
DESCRIPTION
The
Acuro AI25
encoder is available in a single-turn or multiturn 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.
