Multipole Magnets Sales Request:
For our Hall sensor encoder, I am looking for a manufacturer of multipole ring permanent magnets.
Dimensions: OD=*mm, ID=*mm, thickness= *mm (max.*mm)
Number of poles: 12
Configuration: axial
An alternative solution would be to use, instead of the multipole ring, a set of magnet arcs with alternating magnetization. This would also create the desired 12 poles magnet pattern and be equally sufficient. Both solutions are applicable.
Multipole Permanent Magnets Manufacturer China Rare Earth Magnet Limited:
We are specialized in multipole ring magnets with NdFeB and Ferrite magnet materials.
Could you inform us which material and grade you need?
Magnetic Material and Grade:
The magnets will be used for an aerospace application and will be exposed to vacuum, shock (during the launch) and a temperature range of -40 degrees Celsius to +80 degrees. No special coating is required.
The application is for an Encoder using Hall Sensors. The Hall Sensors will be placed *mm away from the magnet and need magnetic field of 120-200 Gauss (depending on the sensor) to operate. The sensors are not fixed though and can be subject of change depending on the magnets.
What kind of material do you recommend for this scenario?
Magnet Photo:
Have you ever bought this magnet? Do you have photos of it?
Magnet Drawing:
I do not own such magnet, but attached to schematic showing the desired magnet.
The magnet can be either a complete ring or each pole can be single magnet. In the second option it would therefore take 12 segment (arc) magnets to construct the whole ring.
I am interested in both options.
Multipole Ferrite Magnets Manufacturer China Rare Earth Magnet Limited:
According to your information, our engineers recommend Y10 Permanent Magnets.
