Complaint
The wheel speed sensor magnet has been used as a core component of the wheel speed sensor for a long time. The AlNiCo magnet can be classified as cast AlNiCo magnet and sintered AlNiCo magnet. For a wheel speed sensor magnet, the sensor manufacturers will use the cast type.
Other Applications for Sensor Magnet
Besides wheel speed sensor, there're thousands of applications for sensor magnet, which require neodymium magnets. Such as hall effect sensor, float sensor, Reed sensor and so on.
Here below is the size range for Neodymium sensor magnets( also can be customized).
Description | Dimension(mm) | Grade | Max working temperature(ºC) |
Block sensor magnets | 7.62*3.18*3.18 | N45H | 120 |
19.05*3.18*3.18 | N35H | 120 | |
21.00*7.00*4.70 | N35H | 120 | |
Disc sensor magnets | 6.35*6.35 | N35H | 120 |
4.4*6.00 | N35SH | 120 |
Advantages
Alnico magnets are very resistant to temperatures up to 525°C and retain their magnetic properties up to high temperatures.
Alnico magnets have a high resistance to acids and other chemicals.
Alnico magnets have a high residual induction.
Alnico magnets are insensitive to corrosion.
When sintering and melting, Alnico magnets can also be manufactured in very complex ways.
