Shopping tips

Thanks to the universal socket profile, it fits many types of clips used in shops. Some very rare securities require dedicated openers from the manufacturer.
It is an extremely strong neodymium magnet, many times stronger than standard household magnets. Weaker magnets (e.g., 6000 Gs) may not open modern, stronger clips.
We require an active VAT number to verify the legality of conducting business activity. We do not fulfill orders from individuals for this assortment.
The detacher has threaded mounting holes, allowing stable and secure attachment. 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. For store staff, the device is safe while maintaining basic safety rules.

Strengths as well as weaknesses of neodymium magnets.

In addition to their pulling strength, neodymium magnets provide the following advantages:

  • Their strength is durable, and after approximately ten years it drops only by ~1% (theoretically),
  • Neodymium magnets are remarkably resistant to demagnetization caused by external field sources,
  • A magnet with a shiny gold surface has better aesthetics,
  • They show high magnetic induction at the operating surface, which increases their power,
  • Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
  • Considering the ability of accurate forming and customization to unique needs, NdFeB magnets can be modeled in a wide range of geometric configurations, which expands the range of possible applications,
  • Key role in advanced technology sectors – they are used in data components, electric motors, diagnostic systems, as well as complex engineering applications.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Problematic aspects of neodymium magnets: weaknesses and usage proposals

  • To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
  • When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
  • Limited possibility of creating threads in the magnet and complicated forms - recommended is cover - magnetic holder.
  • Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these products can be problematic in diagnostics medical when they are in the body.
  • Due to complex production process, their price is higher than average,

Best holding force of the magnet in ideal parameterswhat it depends on?

The lifting capacity listed is a result of laboratory testing conducted under specific, ideal conditions:

  • on a block made of mild steel, effectively closing the magnetic field
  • with a thickness minimum 10 mm
  • characterized by even structure
  • without any air gap between the magnet and steel
  • during pulling in a direction vertical to the mounting surface
  • at temperature room level

Determinants of practical lifting force of a magnet

Please note that the magnet holding will differ subject to elements below, starting with the most relevant:

  • Clearance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
  • Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
  • Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Material type – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
  • Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
  • Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

* Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under shearing force the holding force is lower. Additionally, even a minimal clearance {between} the magnet and the plate reduces the load capacity.

Safety rules for work with NdFeB magnets

Protective goggles

Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Electronic hazard

Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.

Crushing risk

Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Do not drill into magnets

Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Danger to pacemakers

Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Adults only

Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep out of reach of kids and pets.

Handling guide

Use magnets with awareness. Their huge power can shock even professionals. Plan your moves and respect their force.

Power loss in heat

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

GPS and phone interference

Remember: neodymium magnets generate a field that disrupts precision electronics. Keep a safe distance from your mobile, tablet, and navigation systems.

Metal Allergy

Medical facts indicate that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact or select coated magnets.

Warning!
