| Sintered and Bonded Rare
Earth magnets are designed for space-and weight-saving applications. With energy products
ranging from 6 to 27 Mega-Gauss-Oersteds and sizes from only 1mm. in diameter. These
magnets find use in automotive components, small motors, solenoids and sensors when used
with Hall effect magnetoresistive and reed switches. The bonded magnets are compression or
insert molded in intricate shapes, providing low to medium energy. |
