Reference values of the magnet currently in use:
Material: Sintered Neodymium Magnet; gold coating
Reference magnet goodness: 45SH
Temperature stability: 150°C
In order to not rip out of the 45SH permanent magnet from its anchorage, the drawing is to be supplemented with a peripheral groove. To find the best possible solution, we are open to all suggestions for improvements.
Please offer us tooling costs and unit price separately?
