It is a ready-made mounting element that allows quick creation of a magnetic point. Just pass the thread through the hole in the element and tighten the nut on the other side. Used for mounting sensors, panels, plates, and exhibition elements.
Too strong tightening with a wrench can cause the stud to rotate in the cup or strip the thread. When assembling, use a torque wrench or tighten with feeling. The magnet itself is protected by a steel cup and is very resistant to impact.
Maximum operating temperature is 80 degrees Celsius for the standard version. If you need resistance to higher temperatures, ask about special versions (H, SH). Remember that even momentary overheating can weaken the holder.
Thread size (e.g., M6) is always given in the product name and technical specification. Ensure thread length is sufficient to pass through the hole in your material and tighten the nut. The thread is made of galvanized steel, ensuring corrosion resistance.
Yes, the steel housing (cup) focuses the magnetic field, significantly increasing attraction force on the active side. It is a solution optimized for strong holding with direct contact, not attracting from afar.

Advantages as well as disadvantages of rare earth magnets.

Pros

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They have stable power, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
  • They are noted for resistance to demagnetization induced by external disturbances,
  • The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to present itself better,
  • The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
  • Neodymium magnets are characterized by very 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...
  • Possibility of accurate forming and modifying to specific conditions,
  • Versatile presence in innovative solutions – they serve a role in HDD drives, motor assemblies, diagnostic systems, and multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems

Disadvantages

Characteristics of disadvantages of neodymium magnets: application proposals
  • At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
  • Due to limitations in producing threads and complex shapes in magnets, we recommend using cover - magnetic mount.
  • Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these devices can be problematic in diagnostics medical in case of swallowing.
  • With large orders the cost of neodymium magnets is a challenge,

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what contributes to it?

Holding force of 140.00 kg is a theoretical maximum value executed under standard conditions:
  • with the use of a yoke made of special test steel, ensuring full magnetic saturation
  • possessing a massiveness of at least 10 mm to avoid saturation
  • characterized by smoothness
  • with total lack of distance (no coatings)
  • under vertical application of breakaway force (90-degree angle)
  • at conditions approx. 20°C

Practical aspects of lifting capacity – factors

It is worth knowing that the magnet holding will differ subject to elements below, in order of importance:
  • Clearance – existence of foreign body (paint, tape, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
  • Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
  • Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
  • Smoothness – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
  • Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of NdFeB magnets
Pinching danger

Big blocks can break fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.

No play value

NdFeB magnets are not intended for children. Swallowing several magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.

Impact on smartphones

Remember: neodymium magnets generate a field that disrupts precision electronics. Maintain a separation from your mobile, device, and GPS.

Nickel allergy

Some people have a hypersensitivity to nickel, which is the common plating for neodymium magnets. Prolonged contact might lead to a rash. It is best to wear protective gloves.

Magnet fragility

Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.

Pacemakers

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

Heat sensitivity

Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.

Safe operation

Handle magnets with awareness. Their immense force can surprise even professionals. Stay alert and respect their force.

Combustion hazard

Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.

Electronic hazard

Avoid bringing magnets near a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
