N35-N52 Permanent Strong Neodymium Round Magnets

Among those famous round magnets manufacturers, it is a professional supplier in China, welcome to wholesale small round magnets, neodymium disc magnets, magnet disc, strong round magnets from our factory.

Neodymium round magnet / Disc Magnet
Disc magnets are thin flat round magnets where the thickness does not exceed the diameter. They are the most commonly used neodymium magnet shape and the most versatile shape. Neodymium round magnets are widely used in holding applications where a hole is drilled and the magnet is recessed into the hole. Round magnets are most cost-effective than rectangles and other shapes.

Neodymium round magnet are widely used in magnetic Sensor:
Permanent neodymium magnet discs are often used to spark magnetic sensors in a variety of applications. There are two main styles of magnetic sensor, the reed switch and the Hall Effect.
Several parameters must be determined in order to select the proper neodymium round magnet.
Sensor style (Hall Effect or Reed Switch)
Spark threshold (Hysteresis)
Mechanical movement (Magnet relative to the sensor)
Environmental conditions
Dimensional requirements
Proximity of flux biasing alloy

Hall Effect:

A Hall Effect sensor is usually an integrated circuit which utilizes the ”Hall Effect” for detecting magnetic fields. The IC aspect of the sensor allows for a variety of output options and even a variable voltage out relative to the applied field strength. Some sensors are polarity dependent and as with the reed switch suffer from some hysteresis. Unlike the reed switch the Hall Effect sensor will sense the magnetic flux which is normal (perpendicular) to the IC sensing face. This is usually a single defined plane on the sensor package.
With the development of electronic technology, the degree of electronicisim of cars have become more and more sophisticated.
Excellent vehicle control system can improve the adhesion between the wheels and the ground situation, improving the car’s safety, power and comfort. Magnetic sensors play and key and inseparable role in Automotive chassis control system.
HSMAG offers various neodymium magnets with high consistency performance for sensor manufacturers.

Reed Switch:

The reed switch utilizes two small soft-magnetic elements inside of a glass bulb. The elements change their continuity state in the presence of a magnetic field. A normally open reed switch will close when the proper magnitude and shape field is presented to it. This sensor makes use of the flux components running parallel to the bulb and soft-magnetic elements. This geometry usually requires the magnet to be oriented parallel to the bulb. Inaccurate triggering and ”dead-spots” will be observed when utilizing a magnet oriented perpendicular to the bulb and elements.

These 2 pictures shows an inaccurately spark reed switch. Note the perpendicular orientation of the magnet and associated ”dead spot” triggering of the switch as the round magnet passes.
