Blockmagnet 20.0 x 20.0 x 3.0 mm N45 Nickel - M3 countersunk

Quadratischer Magnet aus Neodym in N45. In der Mitte hat dieser Magnet ein 3,5 mm Loch mit Senkung für eine M3 Schraube damit Sie den Magneten anschrauben können.
Die paarweise Verwendung ist nicht möglich, da der Nordpol immer auf der Senkungsseite ist und sich die Magnete somit abstossen.
Damit die Neodymmagnete nicht brechen oder splittern, versenken Sie die Magnete einfach leicht vertieft im Werkstück und schützen den Rohmagneten vor direkten Schlägen.

• 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.
  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.
