Magnets for sensors

Isotropic Nd-Fe-B bonded magnets used as magnets in various types of sensors.
There are compression molding type and injection molding type and can be chosen by shapes and performance.

Characteristics

  • The compression molding type has high magnetic force by high-density molding.
  • The injection molding type has high shape flexibility and can support thin and large diameter products.
