Do you know the working principle of clothing anti-theft doors?

At present, clothing anti-theft devices have been used by many clothing brands and retail stores. Many branded clothing stores (such as Hongdou) have reported that after installing clothing anti-theft devices, the product loss rate has been greatly reduced, and it is almost zero.

So how much do you know about the principle of clothing anti-theft doors?

The two antennas for transmission and reception are the two basic components of clothing anti-theft devices. There are electromagnetic waves between these two antennas, and these waves are always in the state of transmission and reception. Under normal circumstances, the frequency of these waves is 7.4-8.8MHz, with the middle frequency remaining stable at 8.2MHz. Because of electromagnetic waves, a scanning area will be generated.

Clothing anti-theft cannot be separated from anti-theft tags, but the simple structure of inductive coils and capacitors plays a significant role. Clothing supermarkets use the most advanced technology for anti-theft, which generates an oscillating signal that changes with the scanning area, causing an alarm and achieving the effect of anti-theft on clothing.
