Multipole Ring Magnets for Linear Incremental (off-axis) Position Sensor
Left Images shows the proper placement of a multipole ring over the Linear Incremental (off-axis) Position Sensor. The centerline of the magnetic ring (median Hall sensor scan path) is located over the Hall array. multipole sensor magnet for encoder linear rotary
The magnetic ring is designed such that the pole length lp matches the required length at the scan path (typically the center) of the ring. The IC is oriented in perpendicular with respect to the rotation center.

Marking
The magnet ring has two marks at the backside:
One mark shows the number of poles (44) 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.
Depending on the carrier material, there are several adhesives available to glue the ring to the surface. For general ruggedness and vibration demands, the use of two-component-adhesive (binder + hardener) has proven to be successful in most cases.
Sensor Magnets, While all of our Neodymium magnets at MPCO Magnets have a strong hold with corresponding material, our Neodymium sensor magnets are one of the more intricate. Neodymium is the preferred type of component for magnets due to its strength, so when it comes to the most effective sensor magnets, MPCO Magnets offers the finest.
