Magnetic latching relay has a broad development prospect in the market and is widely used in the market. As the most commonly used type of industrial general relay, it is widely used in various fields of national economy. There are safety, time and monitoring relays in construction, transportation, energy and industry, etc., and relays are essential in the field of automatic control, which are favored by users.
Along with the development of watt-hour meter, magnetic stick relay has become an important and indispensable part of watt-hour meter, to cooperate the installation and use of watt-hour meter, requirements of its small size, load capacity, input and output isolation degree is high, low consumption, low temperature rise, its main technical indicators are also because of the use of different environment, to keep magnetic relay setting, reset voltages, contact circuit, medium pressure, the power consumption of the coil, and the impact current, terminal temperature rise have higher requirements, ensure the reliability and security, and this means that the magnetic stick relay manufacturing process, material, quality control of tooling, etc.
China's magnetic retching relay industry will gradually accelerate the pace of transformation from a "manufacturing power" to a "creation power", and the situation from export-driven to domestic demand and export-driven will become increasingly prominent. Especially after high-end products are tackled and improved, the trend of domestic demand will be more clear.
Communication automotive relays will be the research and development direction of magnetic latching relays. Communication relays have become the largest application market, and the third generation of communication relays have been widely used. With the application of microelectronic technology, the products of solid-state relay are developing in the direction of intellectualization and modularization, and the market demand is rising steadily. As the second largest market for the application of magnetic latching relays in automobiles, the usage of single vehicles is increasing and the varieties are expanding rapidly. Especially, the transformation of automobile power supply system from 14 volts to 42 volts will promote the continuous innovation of technologies. Electromechanical magnetic latching relays have become the first choice for home appliances and electric power products due to their low power consumption in working state. Relay manufacturers continue to introduce new products. The new varieties of relays in China have reached the world level in the mid-1990s, and gradually shortened the gap with the advanced level of foreign countries.
In the application market of magnetic latching relays, the application fields of optical relays, temperature relays, high frequency relays and other special relays are constantly expanding, and the technology, quality and output level of domestic manufacturing are far from meeting the market demand. The development of "Tri-network Integration", especially the development of "Internet of Things" and 4G, will enable new relays such as optical relays and high-frequency relays to achieve greater and faster development, and become a new growth highlight of the magnetic latching relay industry during the "12th Five-Year Plan" period.
In recent years, domestic magnetic stick relay industry rapid development, appeared in numerous enterprises scale enterprises, technical aspects within the advanced science and technology and a new type of magnetic stick relay products on the market are constantly emerging, smaller, suitable for surface mount stick, high reliability and good performance of anti-jamming communication relay demand; The fourth generation of new communication relays needed for 4G development in the future will become the mainstream of its development and improve the reliability and versatility of the equipment.
