Will the supermarket anti-theft eas security hard tag alarm after be cut? [Bohang China]
Supermarket anti-theft devices should be familiar to everyone. They will be seen at the entrance of large and medium-sized supermarkets. However, many supermarket vendors will try their best to imitate the thieves in various experiments after the installation of the supermarket anti-theft system. In order to improve the store's anti-theft anti-theft management.Will the supermarket anti-theft eas security hard tag alarm after be cut? Today, Bohang China will reveal the answer for everyone.
Whether the supermarket anti-theft eas security hard tag alarms or not, we must first understand the working principle of the supermarket supermarket anti-theft eas security hard tag, supermarket anti-theft system generally has anti-theft antenna, supermarket anti-theft eas security hard tag, degaussing decoding equipment, anti-theft antenna by the transmitting antenna and receiving antenna two parts The basic principle is to use the transmitting antenna to transmit the magnetic signal, and the receiving antenna receives the return signal and returns it to the transmitting antenna.
This signal area forms a scanning area, and uses the resonance principle of electromagnetic waves to search for a specific range in its receiving range. Whether there is a valid tag in it, the supermarket anti-theft eas security hard tag is actually a resonant coil. When the anti-theft detonator appears in this scanning area, it will resonate with the magnetic field of this signal area to trigger an alarm.
When the cashier decodes or degauss the anti-theft buckle, the magnetic field of the coil inside the anti-theft buckle will be weakened. This is when the scanning area of the anti-theft antenna is passed, no alarm will occur, and the same principle can be used to determine the supermarket anti-theft. If the buckle is cut, the answer will be no. If the anti-theft buckle is cut, the resonant coil inside will be broken. At this time, the anti-theft buckle is equivalent to an ordinary plastic. Therefore, the supermarket anti-theft eas security hard tag will not alarm if be cut.
