What is the quality of anti-theft hard tags related to?

As an important part of the anti-theft system, the quality of the anti-theft label affects the detection performance of the anti-theft system, not only in the detection distance, but also in the detection rate, so when we buy such anti-theft consumables , how to distinguish its quality, today I will introduce to you how to distinguish the quality problems of anti theft hard tags.
The main components of the anti-theft hard tag are "lock head" and "coil". By distinguishing the quality of the two, the quality of the label can be directly identified. Let's analyze the lock head first. Most of the anti-theft hard tags are independent lock heads. Generally, this is done. Manufacturers of independent lock heads will go to other manufacturers that specialize in independent comparison heads to take ready-made lock heads for processing. Because many independent lock head manufacturers are very small in scale, the processing environment is relatively bad. For the critical component of the hard label, the requirements for the lock head are relatively strict, which will directly affect its future use, whether it can be unlocked smoothly and the life of the lock head. In the independent lock head, it is often seen that due to the harsh processing environment or the use of inferior and rust-prone iron beads, there are too many impurities in it or rust adhesion, which makes the lock unable to be opened, and ultimately damages the product indirectly.

The coil is the core component to analyze the good and bad of the whole anti-theft system. The coil is actually a kind of LC oscillation circuit. In order to reduce the cost of the inferior label, the original copper wire will be changed to copper-clad aluminum wire or directly used to reduce the cost. Therefore, this kind of label is susceptible to moisture oxidation and thus affects the service life. In the process of label processing, there will be a process of bonding the label with an ultrasonic machine, which will have a momentary high temperature, and inferior labels generally use plastic-wrapped wires. The melting point of plastic is very low, so the process of ultrasonic bonding of labels is easy. The coil is melted to cause a short circuit, which directly affects the yield of the product. Therefore, everyone must choose carefully when purchasing anti-theft labels. Ask more, read more, and choose more to buy anti-theft hard labels with quality assurance.
