AS5000-MA4X2H-1 Data Sheet Axial Magnet 4x2x1mm Bomatec #606416 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. Figure 1.
