Frequently asked questions

What badge size fits these holders - will a standard 86x54 mm card work?
Yes, a standard credit-card-size badge of 86x54 mm fits without any issue - this is the most common format for staff and conference badges. The real limit is the steel plate itself: the badge should not be larger than the plate, otherwise the corners overhang and the 3M tape loses grip faster at the edges. Smaller name tags and cards work just as well as long as they fit within the plate's outline. The card format is up to the customer - we only supply the magnetic clasp that attaches to the back of the badge.
We already have lanyard or pin badges. Can they be converted to magnetic ones?
Yes, and this is the most common way our clasps get used - there is no need to order new badges. The clip or pin is removed from the existing badge, and the steel plate that comes with the clasp is stuck on in its place using the included 3M tape. The only condition is a flat, clean back surface for the tape to bond to. PVC cards, plastic inserts and laminated name tags all work without any extra preparation, and converting one badge takes just a moment.
What should a staff badge show, and does it have to carry a surname?
The scope of information on a staff badge is decided by the employer, not by any fixed template - many companies print only a first name and job title, leaving out the surname to limit the personal data visible to customers. This is a data protection decision, so it is worth checking with whoever handles data compliance in the company rather than following a generic pattern. We have no influence on the badge content and do not print it ourselves - we only supply the magnetic clasp that holds the finished badge on clothing.
Can the badge be swapped, for example on a change of role or for a conference?
Yes, the steel plate stays glued to the badge permanently, but the magnetic strip detaches from it at any time - it simply unclips from the plate. When a role or surname changes, the simplest approach is to print a new badge and stick a new plate to it, reusing the same magnetic strip. For one-off events like conferences or training sessions, the same set of clasps can be reused with different badges each time - the plates are inexpensive and are ordered separately from the magnetic strip.
Will the badge rotate, and is it readable from a distance at a counter or reception?
Two-point models such as C321 or C323 hold a badge steadier than a single magnet, since the card rests on two axes and does not spin freely with faster movement. Readability at a distance, however, depends mainly on the badge design itself - font size and contrast - rather than on the clasp, so it is worth using larger print for badges meant to be read at a reception desk or counter. The clasp's job is simply to keep the card from falling and hold it straight on the clothing.
Pacemaker, hearing aid, contactless card - what about safety when wearing the badge?
People with a pacemaker or any other implanted electronic device should not wear a magnetic badge clasp on the chest - this is a rule that cannot be worked around with a different housing or a weaker magnet, and such a person should be given a lanyard or pin badge instead. Contactless RFID cards and magnetic stripes on badges can be demagnetised by prolonged direct contact with a magnet, so it is best not to store them in the same pocket as the clasp. Hearing aids worn close to the chest are worth checking individually with the device manufacturer.
We are ordering badges for a whole team. How many holders to count and what to order with them?
The number of clasps should match the number of people on the team, plus a small spare stock in case a plate is lost or damaged - the badges themselves (cards, name tags, printing) are ordered separately, outside our offer, since we only supply the mounting mechanism. Each clasp already comes with a steel plate and 3M tape, so there is no need to order that separately. It is worth standardising on one model across the team - larger badges or heavier holders work better with a two-magnet version, while light name tags are fine with a single mounting point.

The magnetic holder is safe for delicate fabrics, expensive suits, silk, and shirts. The badge holds stably, does not tilt or hang, which improves employee image. It is the most frequently chosen type of fastening in corporations, hotels, and banks.
Construction includes a module with strong neodymium magnets in plastic and a plate with self-adhesive tape. Thanks to branded foam tape, badge mounting is instant, durable, and sure. The plastic magnet housing is pleasant to the touch, smooth, and safe for the user.
Thanks to the use of neodymium, the holder securely grips through a jacket, thick sweater, fleece, or coat. A larger number of magnetic points prevents the badge from twisting.
For people with a pacemaker, we recommend traditional fasteners on a lanyard, clip, or safe pin. Healthy users can use badges without worrying about their well-being.
Yes, we are a direct importer and fulfill large wholesale orders. We offer discount thresholds and quantity discounts depending on order size.

Pros and cons of Nd2Fe14B magnets.

Benefits

Besides their stability, neodymium magnets are valued for these benefits:
  • Their strength is maintained, and after approximately 10 years it drops only by ~1% (according to research),
  • They are noted for resistance to demagnetization induced by presence of other magnetic fields,
  • In other words, due to the reflective finish of gold, the element becomes visually attractive,
  • Magnetic induction on the surface of the magnet turns out to be strong,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
  • Possibility of individual modeling and adapting to complex requirements,
  • Wide application in modern technologies – they are commonly used in hard drives, electric drive systems, medical devices, as well as industrial machines.
  • Thanks to their power density, small magnets offer high operating force, in miniature format,

Cons

Problematic aspects of neodymium magnets: application proposals
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
  • When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength 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
  • They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing nuts and complex forms in magnets, we propose using a housing - magnetic mount.
  • Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these devices are able to be problematic in diagnostics medical after entering the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what affects it?

The declared magnet strength concerns the peak performance, measured under ideal test conditions, specifically:
  • on a plate made of mild steel, perfectly concentrating the magnetic flux
  • with a thickness of at least 10 mm
  • with a surface cleaned and smooth
  • under conditions of ideal adhesion (surface-to-surface)
  • for force acting at a right angle (pull-off, not shear)
  • in stable room temperature

Lifting capacity in practice – influencing factors

During everyday use, the actual lifting capacity depends on several key aspects, ranked from most significant:
  • Distance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
  • Load vector – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
  • Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
  • Chemical composition of the base – mild steel gives the best results. Higher carbon content lower magnetic properties and holding force.
  • Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.

H&S for magnets
Choking Hazard

Strictly store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are tragic.

Crushing risk

Big blocks can crush fingers instantly. Under no circumstances place your hand between two attracting surfaces.

Do not drill into magnets

Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.

Handling rules

Use magnets with awareness. Their immense force can surprise even experienced users. Be vigilant and respect their power.

Permanent damage

Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Health Danger

Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Compass and GPS

Remember: rare earth magnets generate a field that disrupts precision electronics. Keep a safe distance from your phone, device, and GPS.

Protective goggles

Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Nickel allergy

Certain individuals experience a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Frequent touching might lead to a rash. It is best to use protective gloves.

Protect data

Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.
