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 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. They effectively minimize financial losses, 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.

Apart from their consistent power, neodymium magnets have these key benefits:

They have stable power, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
Their ability to resist magnetic interference from external fields is notable,
Because of the reflective layer of gold, the component looks visually appealing,
They have very high magnetic induction on the surface of the magnet,
Neodymium magnets are known for very high magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the shape),
With the option for fine forming and targeted design, these magnets can be produced in multiple shapes and sizes, greatly improving engineering flexibility,
Wide application in advanced technical fields – they serve a purpose in data storage devices, electric drives, medical equipment or even other advanced devices,
Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of NdFeB magnets:

They may fracture when subjected to a sudden impact. If the magnets are exposed to physical collisions, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture and increases its overall robustness,
High temperatures may significantly reduce the strength of neodymium magnets. Typically, above 80°C, they experience permanent weakening in performance (depending on form). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
Magnets exposed to humidity can degrade. Therefore, for outdoor applications, we suggest waterproof types made of rubber,
The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is not feasible,
Safety concern linked to microscopic shards may arise, when consumed by mistake, which is notable in the health of young users. Additionally, miniature parts from these devices have the potential to disrupt scanning once in the system,
High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications

Caution with Neodymium Magnets

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

Neodymium magnets generate intense magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

Neodymium magnets can become demagnetized at high temperatures.

Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

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

Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.

Neodymium Magnets can attract to each other, pinch the skin, and cause significant injuries.

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

Magnets are not toys, children should not play with them.

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.

Avoid bringing neodymium magnets close to a phone or GPS.

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.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

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 magnetic are fragile and can easily crack as well as shatter.

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

The magnet is coated with nickel - be careful 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Warning!
