Ferrite magnet is a non-metallic magnetic material, known as iron oxide. Its manufacturing process is mainly made of ferric oxide and other metal oxides. Its relative permeability can be as high as several thousand, and its resistivity is 1011 times that of metal.
Now ferrite magnet product is a non-metallic magnetic material which is widely used in the field of high frequency weak current.
There are also many kinds of ferrite magnet, among which, permanent magnet ferrite is also a common material, mainly because it can retain strong magnetic properties for a long time, and can be used for a long time and generate magnetic field, which is also the reason why it is called permanent magnet ferrite.
Ferrite wafer is a magnetic film used in NFC antennas to resist metal shielding interference and enhance the reception sensitivity of induction signals. 13.56MHZ antenna ferrite wafer/film is a high-temperature sintered ferrooxygen material.
In handheld devices such as NFC payment phones and electronic tags, the main function is to reduce the absorption of signal magnetic field by metal materials. Meanwhile, ferrite magnet film itself is a high-temperature sintered ferrite material, which can effectively increase the induction distance by increasing magnetic field strength of ferrite magnet.
RFID|NFC anti-metal material ferrite magnet piece is a functional composite material mainly absorbing electromagnetic waves. It eliminates the back and forth reflection of electromagnetic waves inside the shielding chamber, reduces the interference of clutter to its own equipment, and effectively prevents the interference and injury of electromagnetic radiation to surrounding equipment and personnel. Ferrite magnet is a high-level means to eliminate electromagnetic wave pollution.
Common thicknesses of ferrite magnet sheets include :0.08mm, 0.1mm, 0.2mm, 0.3mm, NFC ferrite sheets. Magnetic refers to flexible magnetic sheets and non-sintered ferrite hard magnetic sheets, which have a single side and a coldlike texture on the back. The product is smooth and the ultra-thin thickness ranges from 0.15mm to 0.5mm.
The functions of NFC soft magnetic chip in NFC equipment are as follows:
(1) to isolate metal and prevent communication wave and metal from skin-effect loss of electromagnetic energy;
(2) to increase the "positive energy" of magnetic field, that is, to make the reaction sensitivity between Reader ANDA Transponder high and the reading distance is long.
