How to choose anti-theft hard tags?

Installed in clothing, bags, household goods, and other goods, used for anti-theft purposes of electronic tags called anti-theft hard tags, alias: anti-theft tags, magnetic tags, anti-theft hard tags, clothing anti-theft buckles, and so on. Many businesses often need clarification when they first purchase anti-theft tags because they look the same anti-theft tags, but the price is completely different. Where are they different? And how to choose an anti-theft tag? Today, we will introduce to determine the good and bad clothing anti-theft buckles mainly looking at the following points:

1. Shell

   Table of Contents

   • Shell
   • Frequency deviation
   • Lock cylinder

• Features: Positive quality superior anti-theft buckle is generally made of new ABS engineering plastics. The naked eye sees the appearance of soft brightness, hand touch feels better, and the surface without obvious impurities; the quality of the anti-theft buckle is generally used to recycle the ABS plastic or to change the stupidity of the production of recycled ABS appearance of brightness is not uniform, the hand touch feeling is relatively poor, the surface is often obvious impurities, to change the stupidity of the new material is difficult to distinguish the appearance of the new material, but to change the stupidity of the more brittle, easy to break. The new material is more difficult to distinguish, but it is more brittle and easier to break.
• Consequences: High-quality new ABS engineering plastics anti-aging power, moderate strength, not easy to break, the conventional environment can generally use more than 10 years picture; recycled ABS engineering plastic closed anti-aging power is poor, more fragile, easy to break, change the stupid material is more brittle, the conventional environment can only be used for 6 months – 3 years picture.

Destructive testing methods:

• Rolling with a hammer, generally good material takes 3-5 or more before breaking and is partially broken, not easy to dismantle; recycled material and poorer material are 1-2 broken and very easy to break into pieces.
• With teeth, ABS new material will have teeth marks and not easy to break; recycled materials and poorer materials are easy to break.
• With a longer needle top lock position, ABS new material is not easy to top through, even in a very strong top through the case is only out of a needle; recycled material is easy to top through, and top through the place will have an explosion-shaped crack.
• 2. Coil

• Characteristics: Positive quality superior anti-theft buckle coil using pure copper wire winding, the general use of radio frequency plastic wire, sound magnetic use of enameled wire, sound magnetic rod is also used in the quality of the coil of good electrical properties, Q value is high, cut open the core of the wire to the light reflection is the color of copper; quality of general use of the sub-quality of the copper-clad aluminum coils made of poorer electrical properties, Q value is low, cut open the core of the wire to the light reflection is the outer circle of copper color, the center of the white.
• Consequence: The high-quality anti-theft buckle alarm detection rate is high, and the damage rate in the use of the label is very low; the low-quality alarm detection rate is low because the aluminum is brittle, easy to break, and the damage rate is high.
• Detection: Whether the vibration is easy to damage, RF tags can be strongly thrown on the ground rebound more than 2 meters, and again to detect whether the label can be alarmed (more than 50, the general quality of the quality of the damage will not be); the same detector detects the detection of the larger spacing for the quality of the product. We can use BH9277 RF detector detection and BH9677B acoustic magnetic detector detection.

3. Frequency deviation

• Features: The positive quality of the anti-theft buckle frequency deviation is small, generally ± 1.5%; the quality of the second will be beyond this range.
• Consequence: Substandard anti-theft buttons may not be able to alarm properly because they are beyond the detection range of the detector.
• Detection tool: BH9818 acoustic magnetic tag detector, BH9808 RF tag detector.

4. Lock cylinder

• Characteristics: High-quality lock cylinder generally use a three-core lock cylinder structure, with hardness and design of the more reasonable steel bowl and spring composition, generally need to go through the rust test, tensile test, spring strength test, etc., tensile test, tensile strength ≥ 48KG; quality of the lock cylinder may be more than one test cannot be passed, tensile test may be less than 30KG, the average adult male will be able to pull it off.
• Consequence: Not after the rust test may cause goods to be stained with rust, If the spring strength is not enough, then ordinary magnets can also open, and if the pull force is less than 30KG, then Pnen adult men can easily pull out the nail.
• Testing: Soak in saline for more than 8 hours without rust water flow; ordinary magnets cannot be opened normally; tensile tester test more than 48KG tension (strength of men can be nailed to the anti-theft buckle in the stronger knitwear, a handheld anti-theft buckle, a handheld good, so that the maximum force pulled out, such as pulling out of the quality of the product).
