What is Telecom Relay

Almost 100% of the relays used in modern SPC exchanges are PCB electromagnetic relays with contacts. Structurally, the vast majority of the first and second generation communication relays are clapping magnetic circuit structure, push rod mechanical transmission, twin contacts are adopted, and the contact material is AgPd alloy. Since the second generation, in order to improve its sensitivity, samarium cobalt high-energy alloy permanent magnets have been used to form a bridge magnetic circuit, but a considerable part of the relays are still monostable.

Design of Telecom Relay

There are many people in China who design and manufacture the first, second and third generation communication relays, but there is no interest in the fourth generation communication relays, which shows that there is still a considerable gap between the overall relay equipment manufacturing level, product design level and production management level of China’s relay industry and the world. These gaps are:

(1) in addition to the relay design applied in aerospace and military, civil and commercial relays lack standard design specifications.

(2) for all kinds of magnetic circuit structures with ultra-small permanent magnets, there is a lack of actual analysis and calculation in the factory, and the relay manufacturer can not correctly describe and use what kind of magnetic circuit structure to form the “three-dimensional field” is the best, especially how to effectively use magnetic energy in the case of small working air gap and large magnetic leakage distribution;

(3) no one has conducted in-depth research, analysis and practicability on new edge materials and processes. Such as ultra-fine electromagnetic wire, high-energy permanent magnet, excellent engineering plastics and relay accessories, the design of communication relay lacks effective technical support.

(4) lack of engineering and technical personnel who not only understand the basic theory, design and process skills of relay, but also know the special manufacturing equipment of relay. Relay product designers and equipment designers and manufacturers are two teams, which lack technical running in. Generally, there is little problem in the design and manufacture of first-generation, second-generation and third-generation communication relays, but I’m afraid they are not so handy when it comes to the fourth generation of ultra-small communication relays.

(5) most high-speed and high-efficiency production lines have good consistency.

Development Trend Telecom Relay


With the rapid development of communication equipment, the space of mounting plate is shrinking. On the premise of not damaging the performance, miniaturization has become an inevitable trend faced by every manufacturer. The size of communication relay has changed from 20.0 from the first generation to the fourth generation × ten × 10.0mm to 10.0 × six point five × 5.0mm, the volume is reduced by more than 6 times.

low power consumption

From the second generation to the fourth generation, the power consumption of communication relay is reduced from 200MW to 100MW, which is reduced by 50%; It also has energy-saving and memory functions, which effectively reduces the input of power supply of the whole machine.



The international standard iec61811-55 for the fourth generation communication relay puts forward more stringent requirements for surge withstand voltage, insulation withstand voltage, insulation spacing for surge protection and isolation between input and output; Good relay parameter consistency and high reliability make the whole machine run without error.

Magnetic system efficiency

Permanent magnet materials will develop rapidly, and the properties of magnetic materials will be improved by adding components. Hard and soft magnetism will be combined to produce materials with high durability and high coercivity; In order to reduce the volume of some high-end communication relays, permanent magnets are no longer used, flat coil system appears, and some adopt electrostatic driving mode.

product mix

The structural form of the third and fourth generation communication relays is quite different from that of the first and second generations. The double coil symmetrical balanced rocker magnetic circuit structure with high-energy permanent magnet is adopted. The contact is spot welded on the belt and then injected into the whole. The requirements for precision, sensitivity and material are higher.

What does customer say about FBELE Company


Our company has just started to import Chinese products from this year and is not very familiar with customs declaration and transportation. FBELE has taken the trouble to help us handle the import, which has solved our worries at home. Very very very good service.


We choose FBELE as our partner because FBELE has its own plastic mold factory, which can help us customize products and provide prototypes, which provides a strong guarantee for us to design new products.
