This type of holder has a integrated threaded stud (screw), making it perfect for mounting in through holes. Thanks to this, you get a solid, magnetized mounting point without welding or gluing. Used for mounting sensors, panels, plates, and exhibition elements.
The screw is solidly seated in the cup, however, moderation must be maintained when tightening the nut. We recommend using spring washers to avoid the need for forceful tightening. The construction is durable and adapted to industrial conditions.
Above this temperature, the magnet may irreversibly lose some of its power. 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. Exact screw dimensions can be found in the product technical table. It is a solid threaded connection, ready for use.
The magnetic system in a cup is more energy-efficient than the magnet itself of the same dimensions. However, such a system works point-wise and requires direct contact with metal.

Pros and cons of neodymium magnets.

Pros

Apart from their superior magnetism, neodymium magnets have these key benefits:
  • They retain full power for nearly 10 years – the loss is just ~1% (in theory),
  • Magnets effectively protect themselves against loss of magnetization caused by foreign field sources,
  • By covering with a lustrous coating of gold, the element acquires an aesthetic look,
  • They are known for high magnetic induction at the operating surface, which increases their power,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Thanks to versatility in constructing and the ability to customize to client solutions,
  • Fundamental importance in future technologies – they serve a role in data components, electric motors, medical devices, as well as modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in miniature devices

Weaknesses

Problematic aspects of neodymium magnets: tips and applications.
  • 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 suffer a drop in force. 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 when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
  • We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
  • Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these magnets can disrupt the diagnostic process medical after entering the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Magnetic strength at its maximum – what contributes to it?

The lifting capacity listed is a measurement result executed under standard conditions:
  • on a block made of structural steel, perfectly concentrating the magnetic field
  • possessing a massiveness of minimum 10 mm to ensure full flux closure
  • with a plane free of scratches
  • with total lack of distance (without coatings)
  • during pulling in a direction vertical to the plane
  • at standard ambient temperature

Determinants of practical lifting force of a magnet

In practice, the real power depends on several key aspects, presented from crucial:
  • Space between magnet and steel – 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.
  • Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
  • Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
  • Steel grade – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
  • Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
  • Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Warnings
Thermal limits

Keep cool. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).

Danger to pacemakers

Individuals with a pacemaker have to keep an absolute distance from magnets. The magnetic field can interfere with the operation of the life-saving device.

Handling rules

Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.

Adults only

Absolutely store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are very dangerous.

Do not drill into magnets

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

GPS and phone interference

Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.

Threat to electronics

Equipment safety: Strong magnets can damage payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).

Crushing risk

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

Beware of splinters

Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. We recommend safety glasses.

Warning for allergy sufferers

A percentage of the population suffer from a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Extended handling can result in skin redness. It is best to use safety gloves.
