This specification defines the dimensional and magnetic properties of a multipole magnetic ring for use with the linear position magnetic encoder for off-axis rotary applications.
One side mangetized Plastic Bonded Strontium Ferrite Multipole Ring Magnet, The sensor magnet contains only the magnetic ring (see picture on the right), the metal carrier is shown for illustration purposes only.
Marking
The magnet ring has two marks at the backside:
One mark shows the number of poles (128) the other mark shows a single digit letter (A-F), which is of no relevance.
Mounting the Magnet Ring
The magnet ring may be mounted directly on magnetic or non-magnetic surfaces. When magnetic surfaces are used, the ring may be mounted on top of the surface, but not immersed in a cavity, as this may weaken the magnetic field of the magnet. When mounting the magnet on a non-magnetic surface, either method is acceptable.
