EAS Anti-theft tag knowledge

There are many types of anti-theft tags. Do you know how to choose them?Here are two more factors.

1, 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.

2, lock cylinder

Features: High quality lock cylinder generally uses three-core lock column structure, with 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 and the pull test may be less than 30KG.

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, one 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).
