Angle Sensor Magnets and Holders
Diametrically-magnetized magnet 
What’s a “diametrically-magnetized” magnet?
Conventional disk magnets have the north pole on one end and the south pole on the other, which is ideal for proximity sensing.

But diametrically-magnetized magnets have the poles on opposite sides of the magnet diameter, making them perfect for angle sensors.

Popular Magnets
We stock five popular diametrically-magnetized magnets for use with our angle sensors:

Magnet Holders
NVE offers two magnet holders for evaluation and prototyping:
 
Magnet holders
 
The holders are machined aluminum. Set screws secure the magnets in the holders and allow magnet position adjustments. There are threaded mounting holes for a thumbscrew to turn the magnet, or the hole can be used to attach the holder to a rotating shaft. A “clockhand” indicator helps track magnet rotation.

The holders drop into AG93x-Series and AG956 Evaluation Kits and are compatible with several popular diametrically-magnetized disk magnets:
