Plastic Bonded Strontium Ferrite Multipole Ring Magnet 72poles – 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.

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.
