Magnet Specification
AS5000-MA4X2H-1
1. General Description
The AS5000-4X2H-1 is an axial magnet used with the AS5510 linear encoder, in order to measure
small linear displacements.
The magnet is mounted on the top of the AS5510. The airgap depends on the desired resolution
and displacement range for the end application.
Material: NdFeB sintered magnet, Ni-coated

4. Magnetic Field Representation
Below in Figure 1, an illustration of the magnet and the AS5510 is shown. The curve plot below the
sensor chip shows the ideal linear range of the magnet seen by the AS5510. Additionally, a magnet
scan of this arrangement can be found in Figure 2 for further reference.
