Performance parameters
External diameter
17 [mm] +0,1/-0,1
Internal diameter
6 [mm] +0,1/-0,1
Height
2,5 [mm] +0,1/-0,1
magnetizing direction along dimension
2,5 [mm]
Direction of magnetization along the height means that one circular surface of a magnet makes the N-pole, while the other – opposite – circular surface refers to the S-pole.
Material
Neodymium
Grade
N42
Maximal hoisting capacity
3,2 [kg]
The pull force was measured by using metal sheet 10 [mm] thick, acting with perpendicular detaching force. The air gap comprised between the metal sheet and a magnet causes reduction in the pull force.
Magnetic field in geometrical center of the magnetic pole surface
0,25 [T]
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].
Coating
Nickel (NiCuNi)
Magnetic moment
5300 [nWb]x[m]
Weight
