  • Product Detail
  • Technical Specifications
Permanent magnets encased with pot shape steel shells are named cup magnets or pot magnets.According to different magnetic materials,cup (pot) magnets are divied into pot neodymium magnet,pot alnico magnet,pot ferrite magnet.Their magnetic strength and prices will be relatively large differences.

Neodymium pot/cup magnets with internal/female threadedare called internal (female) thread neodymium pot magnets.The improved magnetic circuit design allows the required holding force to be achieved through the minimum size.
