Shopping tips

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. 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. 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 and disadvantages of neodymium magnets NdFeB.

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

  • They do not lose their even over around ten years – the decrease of power is only ~1% (according to tests),
  • They remain magnetized despite exposure to strong external fields,
  • Thanks to the glossy finish and silver coating, they have an visually attractive appearance,
  • Magnetic induction on the surface of these magnets is very strong,
  • With the right combination of magnetic alloys, they reach increased thermal stability, enabling operation at or above 230°C (depending on the structure),
  • The ability for custom shaping and adaptation to custom needs – neodymium magnets can be manufactured in multiple variants of geometries, which amplifies their functionality across industries,
  • Wide application in advanced technical fields – they find application in computer drives, rotating machines, healthcare devices as well as technologically developed systems,
  • Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of magnetic elements:

  • They are fragile when subjected to a powerful impact. If the magnets are exposed to external force, it is advisable to use in a steel housing. The steel housing, in the form of a holder, protects the magnet from breakage , and at the same time reinforces its overall robustness,
  • Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
  • Due to corrosion risk in humid conditions, it is common to use sealed magnets made of synthetic coating for outdoor use,
  • Limited ability to create internal holes in the magnet – the use of a external casing is recommended,
  • Safety concern due to small fragments may arise, in case of ingestion, which is notable in the protection of children. Additionally, tiny components from these products have the potential to interfere with diagnostics after being swallowed,
  • Due to a complex production process, their cost is relatively high,

Notes with Neodymium Magnets

 Maintain neodymium magnets away from youngest children.

Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

Magnets will attract each other within a distance of several to around 10 cm from each other. Remember not to insert fingers between magnets or alternatively in their path when they attract. Magnets, depending on their size, are able even cut off a finger or there can be a serious pressure or even a fracture.

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.

Avoid bringing neodymium magnets close to a phone or GPS.

Intense magnetic 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 can demagnetize at high temperatures.

Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.

Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and 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.

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

Strong 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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Avoid contact with neodymium magnets if you have a nickel 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.

Neodymium magnetic are highly susceptible to damage, leading to their cracking.

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 connection between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Keep neodymium magnets away from people with pacemakers.

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.

Pay attention!
