Performance parameters

External diameter

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

Height

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

magnetizing direction along dimension

2

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.

Grade

N38

Magnet type

Neodymium

Maximal hoisting capacity

1,33 [kg]

The pull force was measured by using metal sheet 10 [mm] thick, acting with perpendicular detaching force. With the force acting on the sliding off, the lifting capacity of the magnet will be 5 times smaller. 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

0,18 [T]

Coating

NiCuNi with foam 3M 4920

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].

adhesive

yes

D12x2/N38 - Neodymium magnet


This magnet is circular, cylindrical, shaped like a cylinder or disc.

It is a neodymium magnet, magnetised along the height. It has an excellent adhesive layer 3M or adhesive foam 3M. It is very easy to stick after removing the protective tape. This magnet is very easy to stick to many surfaces. It has been protected against corrosion by nickel plating. It has been manufactured to excellent dimensional tolerances. The maximum operating temperature is no more than 80 degrees Celsius. Neodymium magnets stick to metal surface.
