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.

Two mounting points (in larger models) prevent the holder from rotating and ensure a solid connection. Thanks to the flat construction, they are great for surface mounting without milling.

Model NCM 15x13.5x5 / N38 reaches a capacity of up to 7.00 kg, which is an impressive result for such a flat element. These are some of the strongest solutions for flat mounting available on the market.

Magnets are shielded on three sides by steel, increasing their lifespan and crack resistance. 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.

Strengths as well as weaknesses of neodymium magnets.

Advantages

Besides their exceptional pulling force, neodymium magnets offer the following advantages:

They do not lose magnetism, even after nearly 10 years – the reduction in power is only ~1% (based on measurements),
They retain their magnetic properties even under external field action,
A magnet with a smooth gold surface has an effective appearance,
They are known for high magnetic induction at the operating surface, which increases their power,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
In view of the possibility of flexible molding and customization to unique projects, magnetic components can be modeled in a wide range of shapes and sizes, which expands the range of possible applications,
Versatile presence in electronics industry – they are utilized in mass storage devices, electromotive mechanisms, medical devices, also technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Limitations

Problematic aspects of neodymium magnets and ways of using them

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 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 magnets in rubber or plastics, which secure oxidation and corrosion.
Due to limitations in realizing nuts and complicated forms in magnets, we recommend using casing - magnetic holder.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to be problematic in diagnostics medical after entering the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Holding force characteristics

Maximum lifting capacity of the magnet – what contributes to it?

The declared magnet strength represents the peak performance, measured under optimal environment, meaning:

with the use of a yoke made of special test steel, guaranteeing maximum field concentration
whose thickness is min. 10 mm
with an ground contact surface
with zero gap (no impurities)
during pulling in a direction vertical to the mounting surface
in temp. approx. 20°C

Lifting capacity in real conditions – factors

Effective lifting capacity is affected by working environment parameters, including (from priority):

Clearance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.

Warnings

Shattering risk

NdFeB magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets will cause them breaking into small pieces.

Electronic hazard

Powerful magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Handling guide

Exercise caution. Neodymium magnets attract from a long distance and connect with huge force, often quicker than you can move away.

Permanent damage

Keep cool. Neodymium magnets are sensitive to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Magnetic interference

An intense magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to avoid damaging the sensors.

Product not for children

Neodymium magnets are not intended for children. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.

Nickel coating and allergies

Studies show that nickel (the usual finish) is a common allergen. If you have an allergy, prevent touching magnets with bare hands and choose versions in plastic housing.

Physical harm

Pinching hazard: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.

Mechanical processing

Dust produced during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Medical implants

People with a pacemaker must keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
