Magnets and Actuators Magnetic Actuators Description Littelfuse offers a wide range of magnetic actuators that are packaged in shapes similar to the relative mating sensors. We also offer a limited family of bare magnets with various grades of materials, including ferrite (ceramic), AlNiCo and neodymium iron boron (NdFeB) materials. Rectangular Actuators These rectangular bare magnets and packaged actuators are ideally suited for mounting on a flat surface. They are suitable for use in a wide range of environments, including high-temperature applications. Overall Dimensions Recommended Operating Temp. Retentivity Coercivity Gauss Oersted Max.
