Incremental rotary encoder MNI40N
Technical data
General specifications
Detection type magnetic sampling
Pulse count max. 7200
Model Number
MNI40N
Magnetic, Non Contact
Features
•Clear function verification via twocolor LEDs (red/green)
• Simple installation and adjustment
using assistance functions reduce
costs
• Self-diagnostics including the
magnetic wheel provide quality
assurance
• Internal intelligence provides easy
setup and reliable operation
• The elastomer coating of the
magnetic wheel provides
resistance to dirt as well as
thermal and mechanical shock
• Long service life at high speeds
and temperatures
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.
