The Block sensor magnet is an axial magnet used with the linear encoder, in order to measure small linear displacements.
The magnet is mounted on the top of the sensor. The airgap depends on the desired resolution and displacement range for the end application.
Material: NdFeB sintered magnet, Ni-coated

Neo magnets are typically produced via a powder metallurgy process wherein the alloy composition is melted from raw materials, crushed into a coarse powder, finely milled, compaction pressed, sintered and finish processed.
HSMAG offer and manufacture licensed neodymium iron boron. Our neo magnets are RoHS compliant.

The development of rare earth magnets like Neodymium has given life to a great future for companies that dominate the automobile industry like Toyota. According to their latest news, the Toyota Prius Hybrid car contains about 30 kilograms of rare earth materials. Neodymium magnets have acquired a large percentage of it. The motors that contain Neodymium magnets deliver a high performance when compared to a traditional motor of the same size. Therefore, they are also used in wind turbines as well as generators, where long term efficiency is essential.
