1. Extremely powerful magnetic design: Well-designed neodymium Halbach array.

2. A reasonable thick plate stick together with magnets, which gives a reversed magnetic field conduction.

3. SUS316 stainless steel casing protecting magnets from bumping and corrosion to provide long service life. 

4. High-intensity magnets up to +8,000 gauss. 

5. Withstands working temperatures of up to 150°C (302°F).

It is a planar Halbach Array, configuration appears a rectangular arrangement where neodymium magnets are laid out in rows with  alternating orientations to manipulate magnetic flux for maximum efficiency. As a result, one face of the assembly presents a very strong magnetic field and the opposite face presents a very weak magnetic field. Through the production, it can creat an additional field 30% - 80% without increasing the magnet weight. 

It plays a crucial role as a replacement part for an anti-roll back (ARB) assembly on a rollercoaster as a secondary safety device stopping backwards movement of the ride vehicle.
