Function
The magnetic incremental encoder MNI20 is an ex-
ceptionally robust measurement system in the smal-
lest space. Its highly compact encapsulated housing
gives the sensor its high resistance to harsh environ-
mental conditions. The installation-friendly design re-
duces the installation time considerably.
