Some customers ask, what kind of sensor needs a magnet? The following This article, I hope to help you!
Non-contact sensors use magnetic materials. Such as Hall sensor, car position sensor, motor speed sensor, load cell, security alarm sensor, magnetostrictive displacement sensor, car brake sensor, car wheel speed sensor, magnetron sensor, vehicle speed sensor, water flow sensor, inductive Magnetic sensor, inductive sensor, etc.
The sensor works with the magnetic steel to detect the size of the magnetic field, or to apply the magnetic material to the sensor to detect the ferromagnetic material.
The magnets used in different sensors are different. They are made of sintered NdFeB, injection molded magnetic, ferrite magnetic rings, and bonded NdFeB.
Below we briefly introduce several sensor magnets of our company.
1. Automobile ABS wheel sensor magnet (magnet)
The magnets used in Hall sensors are mainly magnetic rings, and most of them use injection molded ferrite magnetic rings.
Injection molded ferrite radial 18-pole Hall induction magnet
What is the maximum number of Hall induction injection molded ferrite rings?
Number of poles in the magnetic ring: Generally, the number of poles is related to the diameter of your product. The larger the number, the more poles you can make. Welcome to consult!
Injection magnetic product specifications:
Choose from a variety of specifications, depending on your needs.Product application: various wire and equipment.
Magnetic ring classification: Magnetic rings are mainly divided into: anti-interference magnetic ring specifications, ferrite magnetic ring specifications, clip-on magnetic ring specifications, flat magnetic ring specifications, assembled magnetic ring specifications, dual-hole magnetic ring specifications, three-hole magnetic Ring specifications, six-hole magnetic ring specifications, etc.!
2. Mileage sensor
NdFeB rare earth permanent magnet material bonded injection molding, the product has both steel and elasticity; can be molded with metal, plastic and other inserts at one time, simplifying assembly, firm and firm (not easy to fall off and deform); can ensure precision hot melt The state is filled with a cavity, a plurality of pieces, uniform density, and good magnetic field consistency;
3. Oil pressure gauge magnetic steel
Oil pressure gauge magnetic steel features:
1. The oil pressure gauge magnetic steel adopts plastic magnetic neodymium iron boron material, two-pole magnetization method, and the magnetic field strength can be adjusted from 850Gs to 2500Gs.
2. It can be molded once with the needle shaft insert, and the dimensional accuracy is high; it avoids the defects such as dimensional deviation and product crack caused by the secondary assembly process;
3. Unique magnet polymer coating technology, good anti-corrosion effect and uniform magnetic properties.
Other specifications of plastic magnetic NdFeB magnets can be produced according to the specific needs of customers' products.
4. Car odometer magnet
Automotive odometer injection magnetic steel features:
1. The automobile odometer magnetic steel adopts plastic magnetic neodymium iron boron material, two-pole magnetization method, and the magnetic field strength can be adjusted from 500Gs to 2500Gs.
2. It can be molded once with the needle shaft insert, and the dimensional accuracy is high; it avoids the defects such as dimensional deviation and product crack caused by the secondary assembly process;
3. Unique magnet polymer coating technology, good anti-corrosion effect and uniform magnetic properties.
5. Plastic magnetic ring
Injection molding NdFeB magnetic ring is used in high-grade air conditioner motor
Injection magnetic magnetic force: The magnetic field of general injection magnetic is about 1200-1300Gs, and the highest is about 1700Gs.
