The importance of the Automotive Relay industry

In the Automotive Relay industry, we have summed up an experience in the face of so many buyers of automotive relays: Miss a product, miss a market. Why do you say that? Relays contact many customers in the selection, they will purchase a lot of automotive relays, different brands of automotive relays to get back for testing, this is also a long process, because not only the automotive relay as an accessory to test, but also There will be many accessories to test.

Therefore, when purchasing certain accessories, try to choose the right car relay, which can save a little time, after all, there is not only one accessory to be tested. If you miss the time and miss the product, you are missing a market. In order to minimize unnecessary waste, you can choose Yuan Ze relay, we can customize it for you, meet your selection requirements, and serve you in all directions, which is the purpose of relay.
As an Automotive Relay Factory, what do the symbols on the relay mean?
Symbolic representation
The relay coil is represented by a long box symbol in the circuit. If the relay has two coils, draw two long boxes side by side. At the same time, mark the relay's text symbol "J" in or near the long box. There are two ways to represent the contacts of the relay: one is to draw them directly on the side of the long box, which is more intuitive. The other is to draw each contact into its own control circuit according to the needs of the circuit connection. Usually, the same text symbols are marked next to the contacts and coils of the same relay, and the contact group is numbered To show the difference.
There are three basic forms of relay contacts:
The movable contact (normally open, H-type) coil is open when the coil is not energized, and the two contacts are closed after energization. It is indicated by the "H" pinyin prefix.
When the dynamic break type (normally closed, D type) coil is not energized, the two contacts are closed, and after the energization, the two contacts are opened. It is indicated by the "D" pinyin prefix "D".
The switching type (Z type) is a contact group type. This contact group has a total of 3 contacts, that is, the middle is a moving contact, and the upper and lower are each a static contact. When the coil is not energized, the moving contact is disconnected from one of the static contacts, and the other is closed; after the coil is energized, the moving contact is moved, so that the original open state is closed, and the original closed state is opened. The purpose of the conversion. Such contact groups are called switching contacts. It is indicated by the pinyin prefix "Z"
Our company also has MK Relay on sale, welcome to consult.

How to Buy a Good Relay?

As a  Power Relay Manufacturer , I often meet some customers who say that the quality of your relay is still ok, it is more expensive. Some customers say that I want good quality and cheaper prices. Here, we give everyone a generalization. In fact, the good or bad of Power Relay, 60% is determined by the contacts, reeds, outer casing, thin wire, base, etc. of the relay, and 40% of them are assembled in the relay. Determined in the process. Think about it, if the relay parts are poor, how well the relays are assembled on the production line, and will not make good  PCB Power Relays . Just like a chef, you give him poor raw materials, how good his cooking skills are, and he can't fry good dishes. Therefore, if you have a piece of money and a good quality, it will be more expensive. Power Relay So how do we see the relays are good and bad? If you are interested in researching and taking two different brands, you can see the difference if you study it carefully. Take our relay

What Are The Methods For Relay Debugging?

What are the methods for  Relay Debugging ? The following small series explains for you: 1. Before using the relay, check whether there is any damage caused during transportation. Set the relay to the first setting point, turn the movable system to the magnetic pole direction by hand, and then release it. The movable system should be turned back to the original. Position until the stop. 2. When the relay is re-adjusted, it must be guaranteed: a, the axial movement of the movable system is between 0.15 ~ 0.25mm; b. The air gap between the moving piece and the magnetic pole should be uniform. Under any action, the moving piece and the magnetic pole should not touch each other; c. During the action, the movable system must not be stuck in the middle position; d. When the pointer is rotated from the first scale to the maximum scale, the loops of the hairspring shall not touch each other; e. When the contact is in the open position, the total air gap between the static and dy

Analysis Of The Development Prospects Of Relay Industry

In the past ten years, China's information industry has developed rapidly at a rate three times that of other industries. The communications and automotive industries are also moving forward at a rapid pace. At the same time, the home appliance industry has begun to emerge as an important demand driver. With the overall improvement in the quality of life of Chinese products, more and more consumers are interested in new or upgraded appliances, which in turn stimulates the demand of  Power Relay . According to the forward-looking report of China's current relay industry market foresight and investment planning analysis released by Prospective Industry Research Institute, the use of relays in these industries is considerable. With the development of these industries, it will undoubtedly promote the further expansion of the relay market. In 2010, although the number of relay outlets decreased, the value of exports increased, indicating that the added value of the export relays
