Introduction to AM System
The so-called Acoustic Magnetic System (AM) is a resonance phenomenon generated by the tuning fork principle to achieve almost zero false alarm operation. When the frequency of the transmitted signal is consistent with the oscillating frequency of the acousto-magnetic tag, the acousto-magnetic tag, similar to a tuning fork, will cause resonance and generate a resonance signal;
When the receiver detects the continuous resonance signal (adjustable) 4-8 times (every 1/50 second), the receiving system will send an alarm.
Principle of Acoustic Magnetic System
The transmitter of the detection system emits a low-frequency magnetic wave of 58 kHz at 1/75 second intervals, forming a detection area around it. When a tag consisting of two special amorphous metal pieces enters the detection area, it will be received by the matching receiver due to interference or other forms of induction to the electromagnetic field, that is, a resonance signal, which will cause a system alarm.
The characteristics of the am system
The characteristics of the acousto-magnetic system are high anti-theft detection rate, almost zero false positives, unshielded by metal foil, good anti-interference, and wide protected exit (a single system can protect up to 4 meters wide). The acousto-magnetic system has two types of anti-theft tags, hard and soft, to protect most kinds of goods in the mall, but the tags are relatively large in size and high in price.
AM system composition
AM anti-theft system consists of three parts：
●The first is a detector, which consists of a transmitter and a receiver. The basic principle is to use an transmitting antenna to emit an alternating magnetic field, forming an induction zone between the transmitting antenna and the receiving antenna, and using the resonance principle of electromagnetic waves to search for a specific range in the presence of a valid tag (that is, without decoding by the decoder Tag exists), an alarm is triggered when a valid tag appears.
●The second is an acoustic magnetic label. It is cut from the randomly arranged amorphous metal to a size of 58kHz, and enters the detection area to resonate with the polarizer and reflect it to the receiving support.
●The third is the decoder, which is a non-contact device that fails to decode soft tags. When the cashier collects cash, the electronic tag can be decoded without touching the degaussing area; or a device that combines a decoder and a laser barcode scanner to complete the collection and decoding of the product at one time
AM System Applications
When export companies get European and American orders, they generally use anti-theft tags; especially the top 100 supermarket chains in Europe and America, most of them use Bohang's 58kHz acoustic and magnetic anti-theft system. Only when the DR anti-theft label is affixed to the product can it enter European and American supermarkets.
Acoustomagnetic system is the latest technology of anti-theft: including different types of vertical system, channel system and concealed system, there are more than 10 types of models to choose from. It can also be applied to clothing, shoes, hats, bags and daily necessities / food with packaging.
Conclusion
Acoustic-magnetic anti-theft systems are becoming more common in retail businesses. As an anti-theft system product that can reduce the loss of your store, it is worth buying and using. For your store, reducing the cost of theft is increasing your profits. If your store is not yet equipped with an anti-theft system, contact us today.
