  Compared with the fourth-generation signal relay, the area of ​​the fifth-generation signal relay is reduced by 34%, and the weight of a single product is only about 0.5 grams.

Thanks to the sensitive and compact structure, its working time and sound are also greatly reduced, which better meets the needs of the miniaturization of modern industrial machines and can be used in more intelligent scenarios.

  Signal relays for making and breaking circuits and issuing control commands are widely used in industrial and civil fields.

Without it, smart homes, factory equipment, mechanical cars, etc. in daily work life cannot function.

A few days ago, the fifth-generation signal relay with the smallest size and the lowest coil power consumption in the industry was successfully developed and mass-produced in Xiamen.

This product is developed by a local company in Xiamen and has independent intellectual property rights.

  It is reported that the fifth-generation signal relay is directly driven by a microprocessor. Compared with the previous fourth-generation signal relay, not only the power consumption of the coil has been reduced by more than 64%, but the volume has also been reduced by about 40%. Meeting the green requirements for low-carbon emission reduction will boost the green development of electronic equipment.

  A new generation of relays is smaller and more energy efficient

  Signal relays are commonly used devices in automatic control systems and remote control circuits, which are used to turn on and off circuits, issue control commands to equipment and reflect equipment status.

With the rapid development of global digitization, networking, and informatization, and the increasing demand for telecommunications, wireless communications, and broadband transmission and access, the application of signal relays is almost ubiquitous.

  The reporter learned from the research and development company that the biggest feature of the new generation of signal relays compared with previous generations of products is that it has smaller size, lower power consumption, and higher reliability. higher requirements, in line with more and more refined application requirements.

  Compared with the fourth-generation signal relay, the area of ​​the fifth-generation signal relay is reduced by 34%, and the weight of a single product is only about 0.5 grams.

Thanks to the sensitive and compact structure, its working time and sound are also greatly reduced, which better meets the needs of the miniaturization of modern industrial machines and can be used in more intelligent scenarios.

  In terms of performance and energy consumption, the new generation of signal relays abandons the intermediate driving components such as triodes that most relays currently require, and adopts micro-processing to drive directly, which simplifies the circuit design and further saves the space of the whole machine and the cost of components; in addition , This signal relay also has the characteristics of bifurcated moving contact structure, high mechanical life times of more than 100 million times, etc. Its coil power consumption is sharply reduced to 50 mW or even 30 mW, which is more than 64 mW compared to the previous generation. %, can reduce the heat of the whole machine, realize the energy saving, environmental protection and green development of electronic equipment, and further improve product reliability.

  Guo Manjin, chairman and president of Xiamen Hongfa Acoustic Co., Ltd., introduced that the fifth-generation signal relay was officially established for development in early 2020.

At the beginning of product development, the R&D team was guided by market demand and focused on the high-end of the industry.

At present, the fifth-generation signal relay has been mass-produced in the factory. After stable production, the annual output will exceed 100 million, mainly for 5G communication, industrial testing equipment, ultrasonic medical equipment, video surveillance and other fields that are supported by the state.

  Relay iteration under industrial upgrading

  As one of the most important control devices in automatic control and mechatronics, signal relays have gone through four generations of development.

With the continuous reduction of the internal installation board space of communication equipment, the development of signal relays also shows a trend of miniaturization.

With the continuous improvement of the complexity of intelligent communication systems and the requirements for energy saving and consumption reduction, the reliability and green environmental protection requirements of signal relays in related industries are also getting higher and higher.

It can be seen from the product iteration characteristics that each generation of signal relays has been improved in terms of volume miniaturization and performance parameters.

  According to authoritative standards at home and abroad, the intergenerational division of signal relays is mainly based on product dimensions and coil power consumption.

Four generations of products were launched in the 1960s, 1980s, 1990s and early 2000s.

After the development of the signal relay to the fourth generation, due to technical bottlenecks, it has not been updated for a long time.

  Taking Panasonic, an excellent Japanese signal relay manufacturer, as an example, the volume of the third-generation signal relay to the fourth-generation signal relay has been reduced by 40%, but the coil power consumption has not been reduced.

Other international excellent signal relay manufacturers such as Omron, Fujitsu, Tyco, etc. have a similar situation.

  The parameters show that the volume of the fifth-generation signal relay products developed by Chinese companies is about 61% smaller than that of the fourth-generation Panasonic products in Japan, and the coil power consumption has dropped by more than 70%. The magnitude of the upgrade to the fourth generation.

Guo Manjin said that the successful research and development of the fifth-generation signal relay has overcome technical difficulties and barriers in the industry for many years, and has passed relevant international certifications.

In the next step, the company will promote and preside over the development of the global standard for the fifth generation of signal relays.

  In terms of application, industry insiders predict that the advent of the fifth generation of signal relays will promote the rapid development of global multi-industry fields and accelerate the pace of industrial iteration.

For example, the monitoring equipment in the smart home will further reduce the volume of the camera in the future; the equipment for color Doppler examination in the hospital is expected to improve the imaging accuracy, shorten the inspection time and improve the inspection efficiency.
