this magnet has been specifically designed for the magnetic sensors (back bias of hall sensors, such as gear sensor and abs sensor designed.
Hall effect sensors with linear transducers are commonly integrated with digital electronics. This enables advanced corrections to the sensor’s characteristics (e.g. temperature coefficient corrections) and digital interfacing to microprocessor systems. In some solutions of IC Hall effect sensors a DSP is used, which provides for more choices among processing techniques.
According to the different components of the SmCo5 and Sm2Co17, respectively, they are the first generation and the two generation rare earth permanent magnetic material. Because of its raw materials are scarce, the price is expensive and limit the development. Samarium cobalt (SmCo) as the second generation rare earth permanent magnet, not only has a high magnetic energy product (14-28MGOe) and reliable coercivity, and exhibits excellent temperature characteristics in rare earth permanent magnet series. Compared with the NdFeB, SmCo is more suitable for working in high temperature environment.Sm2Co17 (SmCo permanent magnet). sensor block magnet sm2co17
