Shopping tips

Our magnetic detacher is compatible with most (approx. 95-99%) standard magnetic systems. 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 ensure that professional security equipment reaches legally operating sales points.
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. We recommend not bringing the detacher close to pacemakers and other medical implants.

Pros as well as cons of NdFeB magnets.

Besides their tremendous pulling force, neodymium magnets offer the following advantages:

  • They do not lose magnetism, even after nearly ten years – the decrease in lifting capacity is only ~1% (theoretically),
  • Neodymium magnets are distinguished by exceptionally resistant to magnetic field loss caused by magnetic disturbances,
  • By applying a reflective layer of nickel, the element has an elegant look,
  • Magnetic induction on the working layer of the magnet is very high,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
  • Thanks to freedom in designing and the capacity to adapt to specific needs,
  • Key role in innovative solutions – they are utilized in computer drives, brushless drives, diagnostic systems, also multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems

Disadvantages of NdFeB 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 improves its resistance to damage
  • 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 corrode. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • We suggest a housing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
  • Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these products are able to complicate diagnosis medical when they are in the body.
  • With large orders the cost of neodymium magnets can be a barrier,

Optimal lifting capacity of a neodymium magnetwhat contributes to it?

The specified lifting capacity represents the peak performance, measured under ideal test conditions, meaning:

  • using a plate made of low-carbon steel, functioning as a ideal flux conductor
  • possessing a massiveness of minimum 10 mm to avoid saturation
  • with a plane perfectly flat
  • with total lack of distance (no paint)
  • for force applied at a right angle (pull-off, not shear)
  • at standard ambient temperature

Lifting capacity in practice – influencing factors

In practice, the real power depends on several key aspects, ranked from most significant:

  • Air gap (between the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
  • Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
  • Plate thickness – too thin steel does not close the flux, causing part of the flux to be escaped to the other side.
  • Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
  • Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
  • Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

* Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance {between} the magnet’s surface and the plate decreases the holding force.

H&S for magnets

Precision electronics

Remember: neodymium magnets generate a field that disrupts precision electronics. Maintain a separation from your phone, tablet, and navigation systems.

Magnetic media

Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Material brittleness

Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Sensitization to coating

A percentage of the population have a contact allergy to Ni, which is the common plating for NdFeB magnets. Prolonged contact can result in a rash. We suggest wear protective gloves.

Do not drill into magnets

Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.

Swallowing risk

Only for adults. Small elements pose a choking risk, leading to serious injuries. Keep out of reach of children and animals.

Bodily injuries

Big blocks can crush fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.

Operating temperature

Control the heat. Heating the magnet to high heat will destroy its magnetic structure and strength.

Medical implants

For implant holders: Powerful magnets affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.

Do not underestimate power

Handle with care. Rare earth magnets act from a long distance and connect with massive power, often faster than you can react.

Safety First!
