Performance parameters

Length

3 [mm] +0,1/-0,1

Width

3 [mm] +0,1/-0,1

Height

1 [mm] +0,1/-0,1

magnetizing direction along dimension

1 [mm]

Direction of magnetization along the height (the last dimension included in a magnet name) means that the surface of a magnet perpendicular to its height makes the N-pole, while the other surface perpendicular to the height refers to the S-pole;.

Grade

N42

Magnet type

Neodymium

Coating

Nickel (NiCuNi)

do not use in water
Sintered neodymium magnets are brittle (fragile). A neodymium magnet without housing could break after an impact with another strong magnet.

Maximum working temperature

≤ 80 [°C]

For flat magnets and magnets mounted in the open magnetic circuit working temperature may be insignificantly lower. For high magnets and magnets mounted in the closed magnetic circuit working temperature equals max. working temperature for a given material. Curie’s temperature is ~ 310°[C]. Temperature coefficient of remanence TK(Br: approx. ~0,12 %/°[C]. Temperature coefficient of coercivity TK(HcJ): approx. -0,6 %/°[C].
