Magnet Technology Compact 12/2023
“Robust angle measurement with an in shaft-solution”
For many years now, we have been publishing articles on topics worth knowing about and current technologies relating to the use of permanent magnets and permanent magnet systems in industrial applications.
The increasing importance of electricity as an energy source in industry has spurred us on to develop a solution with magnets that are robust against electrical interference fields.
Read about our offer “Robust angle measurement with an in shaft-solution” in our new Magnet Technology Compact 12/2023.
Our applications Brief will be Magnet Technology Compact.

We are looking forward to meet you!
Our Managing Director Dr. Martin Grönefeld will give a presentation on 3D printing of magnetic materials at this year’s RUHR Symposium “Functional Magnetic Materials: Performance Enhancements for Electric Drives and Thermal Management” on 09 October 2019.
Further information is available at http://www.ruhr-symposium.de/.
Magnetfabrik Bonn will be participating in the Electronica 2018 trade fair in Munich. We will be happy to welcome you at our booth 408 in hall B3 from November 13 to 16, 2018.
As in the past years Magnetfabrik Bonn has decided to support the DKMS, the German bone marrow donor center. Instead of sending out Christmas cards and gifts to our business partners, we have donated 5.000 € to help fight leukemia. The DKMS is a non-profit organization we feel connected to, as a lot of our employees are registered as potential donors and some have even donated stem cells already.
We wish you and your loved ones merry Christmas and all the best for 2018.
On the fair Sensor + Test in Nuremberg we have introduced exemplarily a magnet which fulfils the high demands of the multichannel sensors on the angular homogeneity of sensor magnets. You will find closer information with downloads “Applications Brief” 06/2014.
Our reply to the resource issues rare earth: Sensor magnets on material basis hard ferrite in plastic bonding
The encoder magnets introduced here are the result of the further development of our series of plastic-bound magnets for angular sensors. Our objective was to provide a more economical solution compared with magnets on the material basis of rare earth metals, to achieve a greater independence from raw material sources in Asia and to realise shaping and magnetising in a single production process.
We have developed an rotary encoder magnet on a hard ferrite material basis. It is produced in an injection moulding process and magnetised directly in the too. This reduces material and production costs a well as part-specific tool costs.
Summary of technical advantages of encoder magnets made of plastic-bound hard ferrite and plastic-bound NdFeB in comparison.
Advantages of magnets based on hard ferrite: better contour accuracy due to smaller granulation of magnetic filler,
corrosion stability, no irreversible magnetic loss at high temperatures up to 150°C and single level safe manufacturing process.
Advantages of solutions on rare-earth basis (NdFeB): greater field strength, measuring distance at comparable diameter approx. 1-2 mm large, less possibility of external manipulation (greater coercive field) and smaller reversible temperature drift (approx. 13% per 100K instead of 20% per 100K), however, this also causes irreversible losses!
Summary: We are introducing a new magnet concept for a magnet for angular sensors for front-face retrieval. We can offer approx. 30% cost reduction for large serial production; the part-specific tool costs are generally also more economical.
