Anti-theft tag detachers, such as those utilizing neodymium magnets, are a key component of store security systems. Their principle of operation relies on neodymium magnets that neutralize the magnetic lock in the tag, enabling quick and safe removal of the security tag at the checkout. They are highly effective because they allow for repeated use of tags, which is particularly useful in clothing stores, electronics shops, or those selling high-value alcohol. Their benefits include compact size, high reliability, and the ability to open various tag types, 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 as well as disadvantages of neodymium magnets NdFeB.

In addition to their exceptional strength, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after 10 years, the performance loss is only ~1% (according to literature),
They show superior resistance to demagnetization from external magnetic fields,
Because of the lustrous layer of gold, the component looks high-end,
They exhibit elevated levels of magnetic induction near the outer area of the magnet,
These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to build),
Thanks to the flexibility in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in various configurations, which increases their application range,
Wide application in new technology industries – they find application in HDDs, rotating machines, healthcare devices or even high-tech tools,
Thanks to their concentrated strength, small magnets offer high magnetic performance, with minimal size,

Disadvantages of NdFeB magnets:

They can break when subjected to a powerful impact. If the magnets are exposed to physical collisions, it is suggested to place them in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from breakage and additionally strengthens its overall resistance,
They lose strength at elevated temperatures. Most neodymium magnets experience permanent degradation in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Magnets exposed to humidity can degrade. Therefore, for outdoor applications, we advise waterproof types made of coated materials,
The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is risky,
Possible threat linked to microscopic shards may arise, in case of ingestion, which is notable in the context of child safety. It should also be noted that small elements from these assemblies may disrupt scanning if inside the body,
In cases of large-volume purchasing, neodymium magnet cost may not be economically viable,

Notes with Neodymium Magnets

Keep neodymium magnets away from the wallet, computer, and TV.

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

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

Studies show a small percentage of people have allergies to certain metals, including 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.

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.

Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.

Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

Neodymium magnetic are extremely fragile, resulting in breaking.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

People with pacemakers are advised to avoid neodymium magnets.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

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

Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

If the joining of neodymium magnets is not controlled, at that time they may crumble and crack. Remember not to approach them to each other or hold them firmly in hands at a distance less than 10 cm.

Neodymium magnets are the most powerful magnets ever invented. Their power can shock you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

Exercise caution!
