Magnetic stick relay with the continuous development of economy, in the development of the market continuously improve, widely applied to control the start-up, preheating, air conditioning, oil pump, security, audio, communications, navigation, and automotive electronic instrument and fault diagnosis system, the application scope is widespread, has a very broad prospects for development, favored by users, in the market to keep magnetic relay the overall demand is increasing.
Magnetic latching relay is an electric control device, which makes the controlled quantity have predetermined step changes in the electrical output circuit when the change of input quantity (excitation quantity) meets the specified requirements. Magnetic latching relays are widely used in various fields of the national economy, including national economy, transportation, industry and so on. Relays in all fields with automatic control are essential.
Magnetic latching relay is second only to automotive electronic sensor in its application in automobiles. Relay is an important electronic component in the auto parts, its application amount in the car is second only to the electronic sensor. The continuous improvement of automobile comfort and safety will inevitably lead to the increasing demand for automobile relays. The total number of relays used in the average car is expected to rise from about 20 today to 30-35 by 2013.
From the point of view of the client, the users in the field of construction and industry mainly purchase from the complete set of plate and cabinet factories; The construction of industrial projects mainly depends on the selection of relay products by the successful development of the system integrator project; Most users in the OEM market mainly purchase individual magnetic latching relay products, and some users in some industries, such as hoisting equipment, textile machinery and other industries, will purchase low-voltage cabinets from complete sets of plate and cabinet factories.
From the perspective of brand decision-making right, there is another important role -- system integrators, especially design institutes in metallurgy, glass, ceramics, mining and other industries, which have a strong influence on the choice of brand by users. Although the cabinet factory can not make the final purchasing decision, but in the selection process, the cabinet factory can influence the buyer according to its own experience. And for some professional influence is stronger dish cabinet factory, the end user is due to the trust of its own brand and no longer dry involves the selection of components inside the cabinet. The characteristics of industrial magnetic latching relays such as small size and simple principle determine that most of the products of industrial magnetic latching relays are sold through agents. In the industrial magnetic latching relay market, most of the relatively simple products have relatively simple requirements.
With the popularization of computer technology, the demand of magnetic latching relay for microcomputer is increased significantly. The magnetic latching relay with microprocessor will develop rapidly. At the beginning of 80's, the digital time relay produced in the United States can use the instruction to control the magnetic latching relay. The combined development of the magnetic latching relay and microprocessor can form a small and perfect control system. Computer-controlled industrial robots are growing at a rate of 3.5 percent a year. Computer-controlled production systems can now produce a wide range of low-cost relays on a single production line, and perform a wide range of operations and tests automatically.
The development of communication technology has far-reaching significance for the development of magnetic latching relay. On the one hand, due to the rapid development of communication technology, the application of the whole magnetic latching relay has increased. On the other hand, because the optical fiber will be the future information society transmission aorta, in the optical fiber communication, optical sensing, optical computer, optical information processing technology under the promotion of the emergence of optical fiber relay, reed fiber switch and other new relays.
New material with special structure, new materials, high performance composite materials, optoelectronic materials, oxygen and magnetic material, the development of thermal magnetic materials, amorphous soft magnetic materials to develop new magnetic hold relay, temperature relays, electromagnetic relay all has the vital significance, and will appear new principle, the effect of the relay.
The future development direction of magnetic latching relay should be integrated multi-functional, portable and one-time rapid detection and analysis machine, which can be widely used in the rapid detection of food, environment, battlefield, human diseases and other fields.
For example, rapid and sensitive detection of pathogens or pesticide residues in food and drink; Remote detection and control of polluted gases or contaminated metal ions in the environment; Rapid real-time detection of human blood components and pathogens, and rapid detection of biological weapons and explosives on the battlefield.
However, the new generation of magnetic latching relays also face many challenges, such as higher sensitivity, specificity, biocompatibility, integration of multiple technologies, simplified detection methods, preparation process, mass production, cost effectiveness, etc.
Magnetic stick relay has broad prospects of development in the future, the molecular self-assembly process simple and controllable, can achieve rapid replication, and cost is low, the development of magnetic stick relay has a very important role in promoting, is conducive to high sensitivity, low cost, disposable magnetic hold the development of the relay. However, biomolecular self-assembly technology deserves more attention because of its natural biological compatibility and excellent binding performance. It may become another brand new field for the development of magnetic latching relays and promote the development of magnetic latching relays to a higher direction.
