Plastic Bonded Strontium Ferrite Multipole Ring Magnet 128 poles – Linear Position
The linear magnetic position sensor product family measures the linear movement of a multi-pole magnetic strip. Circular multi-pole magnetic rings can also be used in rotary incremental rotation off-axis applications. This high precision product family allows the user to detect linear movement with a resolution as fine as 0.5μm. All products are aimed at applications which require extreme precision, accuracy, dynamic range and ultra-low power consumption.
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.
Multipole Ring Ferrite 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.
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.
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.
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.
