Description
The magnetic incremental encoder MNI40
combines an exceptionally robust measurement
system with intelligent diagnosis and alignment
functions in the smallest space. Its highly compact
encapsulated housing gives the sensor its high
resistance to harsh environmental conditions. The
installation-friendly design and simple guided
adjustment of the sensor using two-color status
LED reduces the installation time considerably.
