Shopping tips

Thanks to the universal socket profile, it fits many types of clips used in shops. However, it will not work with mechanical clips (hook/SuperLock) or specific systems that are not magnetic.
Our opener has a magnetic field strength of approx. 12000-13000 Gauss (Gs). High induction guarantees quick and trouble-free customer service at the checkout without struggling with the clip.
We sell this product exclusively to companies and business entities (B2B). We ensure that professional security equipment reaches legally operating sales points.
It can be used as a freestanding device or permanently mounted to prevent theft. To remove a clip, just apply it with the "head" to the recess in the magnet and gently separate the elements. Fits any checkout stand without taking up much space.
The detacher generates a very strong magnetic field that can permanently damage payment cards, mechanical watches, or phones. We recommend not bringing the detacher close to pacemakers and other medical implants.

Pros as well as cons of rare earth magnets.

Besides their magnetic performance, neodymium magnets are valued for these benefits:

  • Their magnetic field is maintained, and after around ten years it drops only by ~1% (according to research),
  • Neodymium magnets prove to be extremely resistant to loss of magnetic properties caused by external magnetic fields,
  • The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Possibility of individual shaping and adapting to specific requirements,
  • Universal use in high-tech industry – they are used in data components, electromotive mechanisms, diagnostic systems, as well as modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems

Disadvantages of neodymium magnets:

  • They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
  • Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
  • We suggest a housing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated forms.
  • Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Detachment force of the magnet in optimal conditionswhat affects it?

Holding force of 0 kg is a theoretical maximum value performed under standard conditions:

  • using a base made of low-carbon steel, functioning as a magnetic yoke
  • possessing a thickness of minimum 10 mm to avoid saturation
  • characterized by lack of roughness
  • with total lack of distance (no impurities)
  • under axial force vector (90-degree angle)
  • in temp. approx. 20°C

Key elements affecting lifting force

It is worth knowing that the magnet holding may be lower subject to the following factors, starting with the most relevant:

  • Distance (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Material composition – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
  • Surface quality – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
  • Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.

* Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a slight gap {between} the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with neodymium magnets

Material brittleness

Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Allergy Warning

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease handling magnets and use protective gear.

Do not drill into magnets

Dust created during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Data carriers

Data protection: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).

This is not a toy

Always store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are life-threatening.

Permanent damage

Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.

Crushing force

Protect your hands. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Pacemakers

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Impact on smartphones

An intense magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Keep magnets close to a smartphone to avoid damaging the sensors.

Powerful field

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Caution!
