Guys, today, let‘s talk about car sensors and bonded ferrite magnets. As we all know, cars are becoming more and more intelligent, and sensors are indispensable, and bonded ferrite magnets play a super important role in it.
Precise magnetic properties are the primary requirement. Car sensors have to accurately perceive various working conditions, such as speed, steering Angle, such information can not be deviated. Bonded ferrite magnets have to ensure stable and accurate remanence, so that the sensor can capture subtle magnetic field changes at any time, so that the car computer can receive accurate signals, when we drive, such as cruise, automatic parking these functions can play a steady role, if the magnetic ability is not allowed, then these high-tech functions can be all messed up.
Temperature adaptability is also critical. The temperature of the car engine compartment is not low, when running long distances, the temperature can easily soar to 100 degrees, and in the northern winter, it can be cold to tens of degrees below zero. Bonded ferrite magnets must be able to withstand this kind of "fire and ice", no matter what temperature, the magnetic properties can not fluctuate greatly, and always provide reliable support for the sensor, otherwise the sensor is "confused" at high temperature, "strike" at low temperature, and the safety performance of the car can be greatly reduced.
Mechanical strength must pass. The car runs on the road, it‘s hard to avoid bumps and vibrations, and the bonded ferrite magnet in the sensor is too fragile to fall apart after a few shocks, which is not good. It has to be strong enough and tightly "united" together, even if it encounters potholes and sudden brakes, it can remain intact, continue to work steadily, and protect our driving safety.
Chemical stability is also important. The driving environment of the car is complex, and it may come into contact with various oil, water vapor, and corrosive substances in the exhaust gas. Bonded ferrite magnets should have a strong "corrosion resistance" ability, can not be easily eroded by these things, if the surface is corroded, the magnetic properties of the deterioration does not say, but also may affect the life of the sensor, the maintenance cost can go up.
In short, the requirements of the car sensor on the bonded ferrite magnet are quite strict, and all aspects must be excellent enough to ensure that our car is safe and intelligent on the road. Baozi, the next time you see a car sensor, you will not know more about the bonded ferrite magnet inside.
