Known for its high quality, long-lasting miniature scales
and small profile scanning units, NUMERIK JENA now offers a line of encoders
that are non-magnetic. These linear and rotary encoders have been tested in
environments up to 6 Tesla and have no influence on the machine environment.
The encoders also can withstand this high magnetic environment without loss of
accuracy or resolution and are mechanically stable.
Non-magnetic encoders are commonly found in MRI machines, as
well as semiconductor and microscopy fields.
NUMERIK JENA’s non-magnetic LIK linear series has a 20
micron graduation on glass and digital versions can output resolutions to 50
nanometers, where the digitizing electronics reside in the connector. With
loose mounting tolerances of the scanning unit in relation to the 20 micron
scale, and three configurations of mounting the scanning unit, the LIK series
provides excellent motion feedback for high magnetic environments.
The RIK rotary series is a kit style bearingless rotary
encoder including a disk with various diameters and line counts, and
non-magnetic scanning units to match those diameters. The various sized
aluminum disks containing a 20 micron graduation are to be epoxied to the
customer’s hub design. NUMERIK JENA can also adhere the disks to your custom
hub designs at the factory with your exact specifications and lowest runout
errors.
Both encoder systems use the Epiflex Adjustment Tool to
enhance the signal margin during installation on the machine. Long cable
extensions are also possible for high magnetic field environments.
