Overview of Magnets with Holders
A Magnets with Holders unit, which consists of a neodymium-iron-boron magnet, a metal case, copper rings, etc., is generally used to fix car roof lights, cabinets, door stops, and ceilings.
At present, domestic and foreign customers often use magnet units at the design level in automated machinery and equipment, which are relatively versatile and can be changed flexibly according to customer needs.

Product Features of Magnets with Holders
FEATURES
| Neodymium Magnets with Holders | Neodymium magnets are the most powerful magnets of all, and are ideal for reducing size and increasing the performance of devices. The disadvantage is that it is very easy to rust. Cobalt magnet and it are known as rare earth magnets. |
| Cobalt Magnets with Holders | It is officially known as samarium cobalt magnet, with a strong magnetic force second only to neodymium magnet. Its advantage is being not prone to rusting and resistant to high temperature. But it has poor mechanical strength and is easy to be broken, so be careful when using. |
| Ferrite Magnets with Holders | Ferrite magnets have a weak magnetic force but relatively high retentivity, and magnetism is not easy to decay. It has poor mechanical strength and is easy to be broken, so be careful when using. |
| Al-Fe-Ni-Co Magnets with Holders | It has both the advantage of high temperature resistance and excellent mechanical strength. The disadvantage is that magnetism is very easy to attenuate. |

Precautions of Magnets with Holders
All Magnets with Holders materials are very fragile, no alteration is available.
· Magnets with Holders may be damaged if they are subjected to strong impacts. Be careful during use.
· The magnetic field generated by magnets may cause adverse effects on the following items.
Electronic devices such as cell phones, computers, clocks and watches,
and electronic medical devices such as pacemakers.
·The magnetic force may deteriorate when used at above the maximum operating temperature.
· Strong impact or alteration on magnets may cause magnetic force losses.
· In order to avoid direct impact on the magnet, please keep the clearance of at least 0.1 to 0.3mm.
The adsorption force of powerful neodymium Magnets with Holders is about 30% higher than that of standard neodymium magnets. When taken out of the packaging bag, if there aremagnetic objects nearby, it may jump out and be sucked, causing the product to crack. Please be careful when using.Specifications Overview of Magnets with Holders

Magnets with Holders Features
Load {kgf}＝Load N×0.101972
●Don't apply alterations on magnets as they are fragile.
● Magnets with Holders may be damaged by strong impacts applied directly to the magnet surface.
● Magnets with holders have 0.1 to 0.3mm steps to protect the magnet surface from impacts.
● The magnet and holder are connected by adhesive.
“Attraction Force" indicates the power of lifting the mating material SS400 (polished surface of 10mm thick plate).
