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

Magnet type
Neodymium
Maximal hoisting capacity
146
[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.
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].

200X30X20/N38 - Neodymium magnet
This is a plate magnet. It is rectangular in shape. Bar magnet
It is a neodymium magnet, magnetised along the height. It has two poles, which means it is double-sided. 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. You can attached magnet to surfaces made of ferromagnetic materials.
