  • The product conforms to the European RoHS Community legislation

    The product conforms to the European RoHS Community legislation The product conforms to the European RoHS Community legislation (2002/95/EG - 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.

Magnet wird benötigt für den Bau einens Mendocino-Motors. Die Kraft (das Magnetfeld) ist unglaublich. Preis/Leistung OK.

Produkt erfüllt voll die angegebenen Daten

Die Tragkraft ist sehr gut. Habe mit beiden Magneten eine schwere Balkontür zum schließen gebracht und es zieht auch nicht rein. Vorsicht nur: die äußere Legierung ist relativ empfindlich für Kratzer und Macken. Bei einem Magnet ist eine Ecke abgesprungen
