Introduction to the principle and characteristics of induction coil of access control card
Information from:internet Published on:2022-03-02
When Xiaobian talks about induction coil, we all feel very familiar with it. The access control card should be familiar to everyone and used frequently and widely, especially in daily life and work. You need the access control card when you go home from work, and you also need the access control card when you go to work. The access control card is a very convenient thing. It is generated by electromagnetic induction. As long as you hold a corresponding access control card, such as going home, you only need to take out the access control card and gently stick it to the induction receiver, the door will open automatically. As long as the access control card is not lost, the access control card is very safe, safe, time-saving and convenient compared with the traditional key. We go to work and rush out. As long as we have the access card, the door doesn't need to be locked. Just close the door and brush it gently when we go in. How convenient and time-saving. The most important core component of our access card is the induction coil inside, which is called the induction coil of access card. It is very simple to distinguish the pros and cons of the access card. You only need to watch the manufacturer of the induction coil in the access card and the inspection and verification of the access card. Such access card is safe and reliable. The induction coil of access control card is mainly used in all kinds of smart cards and access control systems. Principle of induction coil of access control card: Using all kinds of wire materials (0.012-2mm), we carry out high-quality winding, welding, measurement and other automatic and semi-automatic process production according to customer requirements. Using high-quality coils and high-quality raw materials, we specialize in the production of VCM coils, motor coils and POS machine coils, and are the leaders in the field of manufacturing various induction coils. Features of smart card induction coil: It has simple and reliable structure, only automatic winding machine, artificial mucosa, high inductance accuracy, small distributed capacitance, high self harmonic frequency, small temperature coefficient, good stability and strong anti-interference ability. It is an inductor that can be used at high frequency. Smart card induction coil can usually be used as current transformer, which has wide frequency band, small volume, light weight, convenient for digital measurement and microcomputer protection.
