Rozruszniki Serca

Osoby z rozrusznikiem muszą zachować dystans min. 10 cm.

Nie dla dzieci

Ryzyko połknięcia. Połknięcie dwóch magnesów grozi śmiercią.

Kruchy materiał

Magnes to ceramika! Uderzenie o inny magnes spowoduje odpryski.

Do czego użyć tego magnesu?

Sprawdzone zastosowania dla wymiaru 15x10x2 mm

Elektronika i Czujniki

Idealny jako element wyzwalający dla czujników Halla oraz kontaktronów w systemach alarmowych. Płaski kształt (2mm) pozwala na ukrycie go w wąskich szczelinach obudowy.

Modelarstwo i Druk 3D

Stosowany do tworzenia niewidocznych zamknięć w modelach drukowanych 3D. Można go wprasować w wydruk lub wkleić w kieszeń zaprojektowaną w modelu CAD.

Meble i Fronty

Używany jako "domykacz" lekkich drzwiczek szafkowych, gdzie standardowe magnesy meblowe są za grube. Wymaga wklejenia w płytkie podfrezowanie.

Our magnetic detacher is compatible with most (approx. 95-99%) standard magnetic systems. However, this is the strongest and most universal magnetic version available on the market.
Our opener has a magnetic field strength of approx. 12000-13000 Gauss (Gs). 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. It is a shop equipment element, not a consumer product.
It can be used as a freestanding device or permanently mounted to prevent theft. It is a maintenance-free, mechanical device always ready for work. The aluminum housing is aesthetic, easy to clean, and durable.
A safe distance (min. 15-20 cm) should be kept from electronics, hard drives, and data carriers. For store staff, the device is safe while maintaining basic safety rules.

Advantages as well as disadvantages of neodymium magnets.

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

  • They do not lose power, even after approximately ten years – the drop in power is only ~1% (theoretically),
  • They have excellent resistance to magnetic field loss as a result of opposing magnetic fields,
  • A magnet with a metallic gold surface has better aesthetics,
  • Magnetic induction on the top side of the magnet is maximum,
  • Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to modularity in forming and the ability to adapt to unusual requirements,
  • Universal use in electronics industry – they are used in computer drives, drive modules, medical equipment, also industrial machines.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages of neodymium magnets:

  • To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
  • Limited possibility of making nuts in the magnet and complex forms - recommended is cover - magnet mounting.
  • Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small components of these magnets are able to 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

Optimal lifting capacity of a neodymium magnetwhat it depends on?

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

  • using a sheet made of mild steel, functioning as a magnetic yoke
  • possessing a massiveness of min. 10 mm to avoid saturation
  • characterized by even structure
  • under conditions of ideal adhesion (surface-to-surface)
  • under axial application of breakaway force (90-degree angle)
  • at ambient temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

Holding efficiency impacted by specific conditions, including (from most important):

  • Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
  • Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
  • Plate texture – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
  • Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

* Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a slight gap {between} the magnet’s surface and the plate lowers the lifting capacity.

Safety rules for work with neodymium magnets

Handling guide

Handle magnets with awareness. Their huge power can surprise even professionals. Be vigilant and respect their force.

Risk of cracking

Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Crushing risk

Large magnets can crush fingers in a fraction of a second. Never place your hand between two strong magnets.

GPS and phone interference

Note: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, tablet, and GPS.

Combustion hazard

Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.

Adults only

Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from children and animals.

Heat sensitivity

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.

Cards and drives

Intense magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.

Danger to pacemakers

For implant holders: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or request help to handle the magnets.

Warning for allergy sufferers

It is widely known that nickel (standard magnet coating) is a strong allergen. If you have an allergy, prevent direct skin contact or choose coated magnets.

Caution!
