Shopping tips

It opens popular clips like Golf, Ink Tag, RF, AM, and other common clothing securities. However, it will not work with mechanical clips (hook/SuperLock) or specific systems that are not magnetic.
Such power is necessary to release the spring lock inside the anti-theft clip. Weaker magnets (e.g., 6000 Gs) may not open modern, stronger clips.
We require an active VAT number to verify the legality of conducting business activity. We ensure that professional security equipment reaches legally operating sales points.
The detacher has threaded mounting holes, allowing stable and secure attachment. It is a maintenance-free, mechanical device always ready for work. The aluminum housing is aesthetic, easy to clean, and durable.
A safe distance (min. 15-20 cm) should be kept from electronics, hard drives, and data carriers. For store staff, the device is safe while maintaining basic safety rules.

Pros as well as cons of neodymium magnets.

Apart from their consistent holding force, neodymium magnets have these key benefits:

  • They do not lose magnetism, even during nearly ten years – the decrease in power is only ~1% (theoretically),
  • They retain their magnetic properties even under close interference source,
  • By using a reflective layer of nickel, the element acquires an modern look,
  • Magnetic induction on the working layer of the magnet remains exceptional,
  • Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
  • Possibility of precise modeling as well as adapting to defined conditions,
  • Universal use in electronics industry – they are used in computer drives, brushless drives, medical equipment, as well as complex engineering applications.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in small systems

Disadvantages of NdFeB magnets:

  • Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
  • When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
  • 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 creating threads and complex shapes in magnets, we propose using a housing - magnetic mount.
  • Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small components of these magnets can be problematic in diagnostics medical when they are in the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Maximum lifting capacity of the magnetwhat affects it?

The force parameter is a theoretical maximum value executed under standard conditions:

  • using a sheet made of low-carbon steel, acting as a circuit closing element
  • with a thickness of at least 10 mm
  • with an ideally smooth touching surface
  • without any air gap between the magnet and steel
  • for force acting at a right angle (pull-off, not shear)
  • at ambient temperature room level

Lifting capacity in real conditions – factors

It is worth knowing that the application force will differ depending on elements below, starting with the most relevant:

  • Gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
  • Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
  • Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
  • Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

* Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap {between} the magnet’s surface and the plate decreases the lifting capacity.

Safety rules for work with NdFeB magnets

Caution required

Handle magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and respect their force.

Keep away from computers

Do not bring magnets near a purse, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.

Medical interference

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

Serious injuries

Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.

Threat to navigation

A powerful magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Do not bring magnets close to a smartphone to prevent damaging the sensors.

Power loss in heat

Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.

Dust explosion hazard

Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Allergy Warning

Some people have a sensitization to nickel, which is the typical protective layer for neodymium magnets. Frequent touching can result in skin redness. We suggest wear protective gloves.

No play value

Strictly keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.

Beware of splinters

Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Attention!
