Shopping tips

Channel holders are some of the most efficient mounting magnets, built based on a steel U-profile (trough). They are widely used in industry for fixing guards, flaps, doors, and in robot grippers.
These holders usually have one or two mounting holes with a chamfer (conical), which allows their stable screwing. Hole spacing allows secure fixing even in difficult conditions.
Thanks to the short-circuiting of the magnetic field by steel side walls, holding force is concentrated and very large. Even a small channel holder can surprise with its power, surpassing pot magnets.
The construction is mechanically very robust, allowing use in difficult workshop and industrial conditions. They are ideal for heavy doors, machine flaps, molds, and fastening systems in industry.
The steel housing is usually galvanized, providing basic protection against corrosion. With constant contact with water, corrosion may appear, so we do not recommend them for work in rain without additional protection.

Advantages and disadvantages of neodymium magnets.

Besides their exceptional strength, neodymium magnets offer the following advantages:

  • They do not lose power, even over around ten years – the drop in strength is only ~1% (based on measurements),
  • They have excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
  • A magnet with a smooth gold surface looks better,
  • Magnetic induction on the working layer of the magnet is impressive,
  • Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
  • Possibility of accurate machining as well as modifying to defined needs,
  • Wide application in modern technologies – they are commonly used in data components, electric drive systems, medical devices, also multitasking production systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages of neodymium magnets:

  • At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • Due to limitations in producing nuts and complicated forms in magnets, we recommend using cover - magnetic mount.
  • Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these products are able to 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

Optimal lifting capacity of a neodymium magnetwhat it depends on?

Breakaway force was determined for ideal contact conditions, assuming:

  • on a block made of mild steel, optimally conducting the magnetic flux
  • possessing a massiveness of minimum 10 mm to avoid saturation
  • characterized by smoothness
  • without the slightest insulating layer between the magnet and steel
  • for force acting at a right angle (pull-off, not shear)
  • at standard ambient temperature

What influences lifting capacity in practice

Real force is influenced by working environment parameters, such as (from priority):

  • Distance – the presence of any layer (paint, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
  • Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
  • Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
  • Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
  • Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
  • Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.

* Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance {between} the magnet’s surface and the plate decreases the lifting capacity.

H&S for magnets

ICD Warning

Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

Conscious usage

Handle magnets consciously. Their immense force can surprise even professionals. Stay alert and respect their power.

Magnet fragility

Beware of splinters. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Threat to electronics

Data protection: Strong magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

Precision electronics

Remember: rare earth magnets generate a field that confuses sensitive sensors. Keep a separation from your mobile, device, and navigation systems.

Flammability

Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Pinching danger

Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Power loss in heat

Avoid heat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).

Danger to the youngest

Absolutely keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are tragic.

Nickel coating and allergies

Some people have a contact allergy to nickel, which is the common plating for neodymium magnets. Frequent touching can result in a rash. We recommend use safety gloves.

Security!
