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 2.
