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 main and most important advantage is that the magnet does not puncture or damage clothing. 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.
The set includes a strip with magnets (put under clothes) and a steel plate with tape (on the outside). The outer part has strong 3M foam tape, to which a business card or plastic case is stuck. Magnets are hidden in an aesthetic plastic housing that does not irritate the skin.
Attraction force is sufficient to hold the badge even on winter clothing. We offer versions with two or three magnets, which further increases stability and strength.
For people with a pacemaker, we recommend traditional fasteners on a lanyard, clip, or safe pin. The magnetic field is point-based, short-range, and does not negatively affect a healthy person's body.
We serve advertising agencies, printing houses, hotels, and corporations, offering attractive prices for bulk purchases. You can order samples to check the quality before a larger purchase.

Pros as well as cons of Nd2Fe14B magnets.

Pros

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They retain full power for nearly ten years – the loss is just ~1% (in theory),
  • Magnets very well protect themselves against loss of magnetization caused by external fields,
  • By using a reflective coating of nickel, the element presents an proper look,
  • They show high magnetic induction at the operating surface, which increases their power,
  • Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
  • Thanks to freedom in constructing and the capacity to modify to specific needs,
  • Wide application in modern industrial fields – they find application in data components, electric drive systems, diagnostic systems, also industrial machines.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems

Cons

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
  • Do not exceed this material temperature limit: 80°C. Overheating may permanently weaken the magnet.
  • When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
  • Limited ability of making threads in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
  • Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small elements of these products can complicate diagnosis 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

Holding force characteristics

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

The specified lifting capacity refers to the maximum value, recorded under laboratory conditions, namely:
  • using a plate made of high-permeability steel, functioning as a ideal flux conductor
  • with a cross-section of at least 10 mm
  • with an polished touching surface
  • without any air gap between the magnet and steel
  • during detachment in a direction perpendicular to the mounting surface
  • in temp. approx. 20°C

Key elements affecting lifting force

Effective lifting capacity is influenced by working environment parameters, including (from most important):
  • Clearance – existence of any layer (paint, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Chemical composition of the base – mild steel gives the best results. Higher carbon content lower magnetic permeability and lifting capacity.
  • Smoothness – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

Safety rules for work with neodymium magnets
Thermal limits

Do not exceed the maximum operating temperature stated in the specifications of the particular product. The limit depends on the material, geometry and operating arrangement; there is no single threshold for all neodymium magnets. Overheating can permanently weaken a magnet.

Shattering risk

Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Nickel allergy

Studies show that nickel (the usual finish) is a common allergen. If your skin reacts to metals, avoid direct skin contact and select versions in plastic housing.

Powerful field

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

Bodily injuries

Big blocks can crush fingers in a fraction of a second. Never put your hand between two attracting surfaces.

Fire risk

Powder created during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Impact on smartphones

A strong magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid damaging the sensors.

Do not give to children

Always keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.

Electronic devices

Powerful magnetic fields can erase data on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.

Medical interference

People with a pacemaker should maintain an absolute distance from magnets. The magnetic field can interfere with the operation of the implant.
