How to choose anti-theft EAS tags?
Installed on clothing, bags, lifestyle goods and other goods, electronic tags used for anti-theft purposes are called anti-theft hard tags, also known as: anti-theft buckle, magnetic buckle, anti-theft hard buckle, clothing anti-theft buckle. Many merchants often tangled when they purchase anti-theft tags for the first time, because the price of the same anti-theft tags is completely different! ! ! Where are they different? How to choose the anti-theft buckle? I will introduce it to you today, and judge the quality of the clothing anti-theft buckle mainly depends on the following points:
1, the outer shell
Features: The anti-theft buckle with excellent quality is generally made of new ABS engineering plastics. The appearance of the naked eye looks soft, the touch is good, the surface has no obvious impurities; the quality anti-theft buckle is generally made of recycled ABS plastic or modified. The appearance of recycled ABS is uneven, the touch feeling is relatively poor, the surface often has obvious impurities, and the appearance of the new material is difficult to distinguish, but it is more brittle and easy to break.
Consequences: The high-quality new ABS engineering plastic has strong anti-aging ability, moderate strength and is not easy to be damaged. The conventional environment can generally be used for more than 10 years; the recycled ABS engineering plastic plaque has poor anti-aging ability, is fragile, easy to break, and is more brittle. The general environment can only be used for 6 months - 3 years.
Destructive testing method:
A, with a hammer to roll, generally good material 3-5 or more will be damaged, and is partially damaged, not easy to remove; recycled materials and poor materials will break under 1-2, and easily broken into pieces.
B, bite with teeth, ABS new material will have tooth marks, not easy to break; recycled materials and poor materials are easy to break.
C, with a longer needle top lock position, ABS new material is not easy to wear through, even in the case of a large force on the top, only one needle is out; the recycled material is easy to wear, and the top wear will have a crack .
Features: The coil of positive quality and anti-theft buckle is made of pure copper wire. The general radio frequency uses plastic wire, the magnetic magnetic wire uses enameled wire, the magnetic magnetic bar also uses high quality, the coil has good electrical performance and high Q value. After the cut, the core reflects the light on the copper; the quality is usually made of copper-clad aluminum coil, the electrical performance is poor, and the Q value is low. After the cut, the core reflects the outer ring of copper and the center is white.
Consequences: The high-quality anti-theft buckle has a high alarm detection rate, and the damage rate during the use of the label is extremely low; the quality of the alarm detection rate is low, because the aluminum is brittle, easy to break, and the damage rate is high.
Detection: Whether it is easy to damage when vibrating, the RF tag can be thrown on the ground and bounce more than 2 meters, and then the tag can be detected again (more than 50, generally high quality will not be damaged); the same detector detects a large detection interval It is a quality product. It can be detected by BH9277 radio frequency detector and detected by BH9677B magnetic and magnetic detector.
3, frequency deviation
Features: The frequency deviation of the anti-theft buckle with good quality is small, generally ±1.5%; the quality will exceed this range.
Consequences: The quality anti-theft buckle may not be able to alarm properly due to exceeding the detection range of the detector.
Testing tools: BH9818 acoustic magnetic label detector, BH9808 radio frequency label detector.
4, lock cylinder
Features: The high-quality lock cylinder generally uses a three-core lock cylinder structure, and is composed of steel bowl and spring with reasonable hardness and reasonable design. Generally, it needs to pass anti-rust test, tensile test, spring strength test, etc., tensile strength, tensile strength ≥48KG; the quality of the lock cylinder may exceed one test can not pass, the pull test may be less than 30KG, generally adult males can break it.
Consequences: If the anti-rust test does not pass the rust, the product may be rusted. If the spring strength is not enough, the ordinary magnet can be opened. When the pulling force is less than 30KG, the adult male can easily pull out the nail.
Detection: no more rust water flows out of the saline solution for more than 8 hours, the ordinary magnet can not be opened normally, and the tensile tester tests more than 48KG pull force (the man with greater strength can nail the anti-theft buckle on the stronger knitwear, a hand-held anti-theft buckle A hand-held product, so that the maximum force is pulled out, such as pulling out is a quality product).
