Installation and Mounting Considerations

Neodymium block magnets can be incorporated into custom assemblies using suitable mechanical retention systems, housings or adhesives.

The most appropriate installation method depends on the application.

General Installation Recommendations

1. Confirm the required magnetic holding performance.

2. Check the dimensions of the installation space.

3. Identify the magnet's polarity and magnetisation direction before assembly.

4. Ensure the target surface is magnetically compatible.

5. Select a suitable retention method.

6. Avoid excessive mechanical pressure on the magnet.

7. Protect the magnet from impact and repeated collisions.

8. Test the completed assembly under realistic operating conditions.

Important: Do not drill, cut, grind or machine finished neodymium magnets. They are brittle and may fracture, while machining dust can present a fire hazard.
