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. The device is permanently magnetized and does not lose its power over time of use.
We sell this product exclusively to companies and business entities (B2B). We do not fulfill orders from individuals for this assortment.
The device can be screwed to the cash counter top with screws (holes are in the base) or recessed into the top. The magnet requires no electrical power, batteries, or cables. Fits any checkout stand without taking up much space.
Do not put credit cards or phones directly on the magnet. The field itself is concentrated in the upper part of the device (in the socket) and fades quickly with distance.

Pros as well as cons of neodymium magnets.

Apart from their consistent magnetic energy, neodymium magnets have these key benefits:

  • They retain magnetic properties for almost ten years – the loss is just ~1% (based on simulations),
  • They possess excellent resistance to magnetism drop due to opposing magnetic fields,
  • In other words, due to the aesthetic finish of gold, the element gains visual value,
  • Neodymium magnets create maximum magnetic induction on a small surface, which allows for strong attraction,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
  • Due to the possibility of flexible molding and customization to unique solutions, neodymium magnets can be created in a wide range of forms and dimensions, which expands the range of possible applications,
  • Huge importance in innovative solutions – they are utilized in mass storage devices, electromotive mechanisms, medical equipment, and industrial machines.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Cons of neodymium magnets: tips and applications.

  • To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • We recommend a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complex shapes.
  • Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these devices can be problematic in diagnostics medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Best holding force of the magnet in ideal parameterswhat contributes to it?

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

  • using a plate made of mild steel, acting as a ideal flux conductor
  • with a cross-section no less than 10 mm
  • with a plane perfectly flat
  • with direct contact (without impurities)
  • under perpendicular application of breakaway force (90-degree angle)
  • in neutral thermal conditions

What influences lifting capacity in practice

In practice, the actual holding force is determined by many variables, presented from crucial:

  • Clearance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Metal type – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
  • Surface quality – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
  • Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

* 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 5 times. In addition, even a minimal clearance {between} the magnet and the plate lowers the lifting capacity.

Safety rules for work with NdFeB magnets

Keep away from computers

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

Magnet fragility

Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Handling guide

Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.

This is not a toy

Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of kids and pets.

Life threat

Individuals with a pacemaker must maintain an safe separation from magnets. The magnetic field can stop the operation of the implant.

Precision electronics

A strong magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness appears, immediately stop working with magnets and wear gloves.

Mechanical processing

Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.

Permanent damage

Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.

Hand protection

Danger of trauma: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
