Ringmagnet Ø 10.0 x 3.4 x 3.0 mm N42 nickel with counterbore north

Product information "Ringmagnet Ø 10.0 x 3.4 x 3.0 mm N42 nickel with counterbore north"

Our smallest ring magnet with a 90 ° countersink that you can attach with a screw.
The 3.4 mm bore is designed for a screw with a diameter of 3 mm.
 
This magnet has the north pole on the depression side.
 
Note: You cannot use two of these magnets in pairs, i.e. the magnets do not stick to one another with the countersink side, but repel each other.
To use this magnet type in pairs, you need the following magnet as a counter magnet: Ringmagnet Ø 10.0 x 3.4 x 3.0 mm N42 nickel with counterbore south.
If this magnet should only stick to metal, the direction of magnetization / polarity is irrelevant.
 
Note: If too much force is applied, neodymium magnets can break. We recommend a maximum tightening torque of 2 Nm when screwing on this magnet.

The product conforms to the European RoHS Community legislation

The product conforms to the European RoHS Community legislation (2002/95/EC - RoHS - Restriction of Hazardous Substances) relating to the use and the employment of certain hazardous substances in electrical and electronic devices.

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.
