A Comprehensive Guide For LED Magnet

2025-02-19

When buying an led display, led magnets are a small component, but their selection and use have a significant impact on the installation, stability, and long-term operation of the display. This article will discuss the key issues of led display magnets and combine the key factors in the led display purchase process to provide you with a comprehensive guide.

1. How to check the model of the led magnet?

Assume that the led magnet used is 1417-M4
14 ：the width or magnetic surface diameter of 14mm
17 ：the magnet height of 17mm
M4 ：the thread specification, that is, the thread diameter is 3.4mm.

2. What are the common led magnet specifications?

Width: 12mm, 13mm, 14mm, 15mm;
Height: 08mm, 13mm, 17mm;
Thread specification: M3=2.6mm, M4=3.4mm

3. What is the main purpose of led display magnets?

LED display magnets are mainly used to fix LED display modules. In rental screens, stage screens and some scenes that require quick installation and disassembly, magnets can quickly fix the display module to the frame, greatly improving the installation efficiency, and also facilitating maintenance and replacement of modules.

4. What are the materials of led display magnets?

Common LED display magnet materials include neodymium iron boron (NdFeB) and ferrite. NdFeB magnets have high magnetic force and small size, but are more expensive; ferrite magnets are relatively cheap, but have weaker magnetic force and larger size. Which material to choose depends on the specific application scenario and budget.

5. What effect does the suction strength of the led magnet have on the installation of the LED display?

The suction strength of the magnet directly affects the fixing stability of the LED display module. If the suction is insufficient, the module may loosen during transportation or use, resulting in poor display effect or even damage. Therefore, it is necessary to select a magnet with appropriate suction strength according to the weight of the display and the use environment.

6. What is the service life of led magnet?

The service life of magnets is usually long, generally up to several years or even longer. However, in harsh environments (such as high temperature, high humidity or strong magnetic field interference), the demagnetization of the magnet may be accelerated. Under normal use, the service life of neodymium iron boron magnets can reach more than 10 years, while the service life of ferrite magnets is generally 5-8 years.

7. What are the installation methods of led magnet?

Common installation methods include adhesive and embedded. Adhesive is to stick the magnet on the display module or frame with glue, which is convenient to install but may not be strong enough; embedded is to embed the magnet into the reserved hole of the module or frame, which is more stable, but the installation process is relatively complicated.

8. What are the options for the size and shape of led magnet?

Magnets come in a variety of sizes and shapes, and the most common ones are round, square and bar. The size should be determined according to the size of the display module and the installation space. For example, a small display module may be more suitable for a small round magnet, while a large module may require a larger square or bar magnet.

9. How to choose a suitable led magnet supplier?

When choosing a magnet supplier, you need to consider the following points: first, the supplier's reputation and quality assurance to ensure that the magnets meet industry standards; second, the supplier's production capacity and whether it can deliver on time; third, whether the price is reasonable. It is recommended to choose a supplier with a good reputation and rich experience, and request samples for testing.

10. What should I pay attention to during the transportation of led magnet?

During transportation, magnets need to be properly packaged to avoid mutual attraction and damage. At the same time, magnets should not be placed together with electronic devices and magnetic storage media (such as hard disks, magnetic cards, etc.) to avoid data loss or damage.
