1. Each module uses 9 N52 NdFEB magnets. After measurement, the tensile force of N52 NdFEB magnets at various
temperatures is as follows:
Temperature
The tension value of each magnet (Kg)
Tension value per module (Kg)
2. The maximum weight of each module is 0.5kg. According to UL2442 standard, 4 times the safety factor is 2.0kg. It can be
seen from the above table that when the temperature is >120 degrees Celsius, the residual pull value of the magnet is close
to 4 times the safety factor, that is, more than 120 degrees is the dangerous area.
