Anti-theft tag detachers, such as those utilizing neodymium magnets, are a key component of store security systems. They work by using a strong magnetic field to unlock the tag's mechanism, enabling quick and safe removal of the security tag at the checkout. They quickly detach tags, minimizing delays in customer service, which is particularly useful in clothing stores, electronics shops, or those selling high-value alcohol. Advantages include ease of use, durability, and versatility, such as round, rectangular, or Sensormatic tags, like those in models RM®#6 from DHIT or Ultra 12000 Gs. Additionally, they provide strong protection against theft, reducing the possibility of goods being taken with an active security tag. It is crucial that detachers are stored in a location inaccessible to unauthorized individuals to enhance the security of the anti-theft system.

Advantages and disadvantages of neodymium magnets NdFeB.

Besides their durability, neodymium magnets are valued for these benefits:

They retain their attractive force for around ten years – the loss is just ~1% (based on simulations),
They show superior resistance to demagnetization from external magnetic fields,
Thanks to the glossy finish and silver coating, they have an visually attractive appearance,
The outer field strength of the magnet shows elevated magnetic properties,
These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to profile),
With the option for tailored forming and personalized design, these magnets can be produced in multiple shapes and sizes, greatly improving engineering flexibility,
Significant impact in new technology industries – they serve a purpose in hard drives, electromechanical systems, clinical machines along with high-tech tools,
Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of magnetic elements:

They may fracture when subjected to a heavy impact. If the magnets are exposed to mechanical hits, they should be placed in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks , and at the same time increases its overall strength,
They lose magnetic force at increased temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the shape and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
They rust in a humid environment. If exposed to rain, we recommend using waterproof magnets, such as those made of polymer,
The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is risky,
Possible threat linked to microscopic shards may arise, if ingested accidentally, which is significant in the family environments. Additionally, miniature parts from these magnets can hinder health screening once in the system,
In cases of large-volume purchasing, neodymium magnet cost is a challenge,

Safety Precautions

Do not place neodymium magnets near a computer HDD, TV, and wallet.

Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Neodymium magnets are delicate and can easily crack as well as shatter.

Neodymium magnetic are extremely delicate, and by joining them in an uncontrolled manner, they will break. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Neodymium magnets are the most powerful magnets ever created, and their strength can shock you.

To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Neodymium magnets can demagnetize at high temperatures.

While Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.

The magnet coating is made of nickel, so be cautious if you have an allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Maintain neodymium magnets far from children.

Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

In the situation of holding a finger in the path of a neodymium magnet, in that situation, a cut or a fracture may occur.

Warning!
