Product information

Flat neodymium disc magnet in N40. The specialty of this magnet is a 5 mm hole. The distance from the outer edge of the magnet to the hole is 5 mm.
Usually it makes sense to screw on strong magnets. However, this magnet can be attached to a string, for example.

No subject to registration under the REACH Regulation.
Safety Notice
NdFeB magnets are hard and brittle. Especially with thinner dimensions / higher adhesive forces, these can easily break or splinter! An uncontrolled impact of two magnets as well as an external, mechanical shock or pressure load should therefore be avoided!
Determination of the magnetic force
The adhesive force of our magnets is determined at room temperature on a polished plate made of steel S235JR (ST37) with a thickness of 10 mm by the vertical withdrawal of the magnet (1kg ~ 10 N). A different value down to -10% compared to the specified value is possible in exceptional cases. In general, the value is exceeded. Please note that for thinner, painted and not absolute plan undergrounds the adhesive force represents only one raction of the specified values.
