It is a ready-made mounting element that allows quick creation of a magnetic point. Mounting consists of inserting the screw into the hole and securing with a nut (e.g., wing nut). Used for mounting sensors, panels, plates, and exhibition elements.
The threaded stud is an integral part of the steel housing, but avoid overtightening 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). Avoid mounting directly on hot engine or machine components.
We use standardized threads that fit typical nuts available in every store. 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.
The magnetic system in a cup is more energy-efficient than the magnet itself of the same dimensions. It is a solution optimized for strong holding with direct contact, not attracting from afar.

Pros as well as cons of Nd2Fe14B magnets.

Benefits

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • Their magnetic field is durable, and after around ten years it decreases only by ~1% (according to research),
  • They possess excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
  • By applying a lustrous layer of silver, the element has an elegant look,
  • They show high magnetic induction at the operating surface, which increases their power,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
  • Possibility of detailed modeling as well as adjusting to atypical conditions,
  • Fundamental importance in modern technologies – they are used in hard drives, electric drive systems, medical equipment, also multitasking production systems.
  • Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of neodymium magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
  • We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in realizing nuts and complicated forms in magnets, we recommend using cover - magnetic mechanism.
  • Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Best holding force of the magnet in ideal parameters – what it depends on?

The declared magnet strength represents the peak performance, obtained under optimal environment, meaning:
  • on a plate made of structural steel, optimally conducting the magnetic field
  • possessing a massiveness of min. 10 mm to avoid saturation
  • with a plane free of scratches
  • without any insulating layer between the magnet and steel
  • for force applied at a right angle (pull-off, not shear)
  • at ambient temperature approx. 20 degrees Celsius

Practical lifting capacity: influencing factors

Effective lifting capacity impacted by specific conditions, mainly (from priority):
  • Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Load vector – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
  • Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
  • Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).

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 75%. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

H&S for magnets
Physical harm

Big blocks can smash fingers in a fraction of a second. Never put your hand between two strong magnets.

Combustion hazard

Mechanical processing of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Magnet fragility

NdFeB magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets will cause them cracking into shards.

Safe operation

Handle magnets with awareness. Their powerful strength can surprise even experienced users. Stay alert and do not underestimate their power.

Health Danger

Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.

Electronic devices

Do not bring magnets close to a wallet, laptop, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Danger to the youngest

Strictly store magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are tragic.

Allergy Warning

Studies show that nickel (the usual finish) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands and opt for encased magnets.

Impact on smartphones

A powerful magnetic field disrupts the operation of compasses in smartphones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.

Operating temperature

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