Surface mount auto speakers with a 70v/100v transformer built in. The 70v/100v transmission is realized in a high-voltage, low-current mode, which makes longer distance transmission and parallel connection of multiple loudspeakers possible. They are an ideal choice for industrial and commercial applications in hotel, school, office and factory where background music and paging is needed.

On the one hand, the number of 5G base stations in China has increased significantly. 5G communication spectrum is mainly distributed in high frequency bands. The higher the frequency, the faster the signal attenuation, and the smaller the coverage area at the same power.

In the 2G, 3G and 4G era, the spectrum of China ’s three major operators is mainly distributed below 2.6GHz, and the spectrum of China Unicom and mobile in the 5G stage is in the 3.4-3.6GHz range. With the increase of frequency, the number of 5G base stations will increase significantly and is expected to reach twice the number of 4G base stations.

On the other hand, the demand for 5G also brings the technological upgrade of connectors. Under the characteristics of 5G low-latency and high-bandwidth transmission, the data transmission volume has been greatly improved, and the traffic density of 5G has been increased to 100 times that of 4G. With the miniaturization and integration of 5G base stations, the space occupied by the connector is further increased. Compression, electromagnetic interference and heat dissipation have also become important issues.

Therefore, 5G has higher requirements for the density, transmission rate, heat dissipation, electromagnetic interference resistance and reliability of the connector, and the value of the connector has been further improved.

With the increase in the number of base stations and the increase in technical requirements, the connector market is expected to grow significantly and enter a high-boom cycle.

According to the forecast of the Ministry of Industry and Information Technology of China, domestic operators' investment in 5G will be 1.5 times that of 4G, and the total investment will reach 1.5 trillion yuan. As for the pace of demand, with the start of 5G construction in 2019, the scale of 5G base station construction will also Will grow rapidly.

Military connector manufacturers have deep technical accumulation and strong competitiveness, which will fully benefit from the growing demand for connectors in the communications field.

For the connector industry practitioners, military connectors should not be unfamiliar. We've all heard of military style connectors. Do you know how the function of military connectors works? The function of connectors in production is the function of connections. But in other industries, what relevant functions will military connectors play? Let's talk about this.

In the maintenance industry, especially in the automobile maintenance industry, the use of military style connectors will bring us a lot of help. In the process of maintenance, after using the connector, there is no need to worry about the other operation of the machine, and no need to worry about the other parts of the car stopping because of the repair.

Another function of connectors is that when military connectors are used, they will have different shape design requirements. Each type of connector will have its own application requirements. Of course, in actual use, we can also choose to use some connectors with shape requirements.

Military style connectors will always have different applications in different industries, but in the process of application are different, the main role of connectors in the production process is to connect different production parts. Military connectors play a simple connection role.

Sunkye is a manufacturer specializing in mil grade connector, connector design and production, devoted to connector design and development for more than ten years. It strives to become a leader in the industry, providing customers with competitive solutions and products.
