Comprehensive industrial and trade enterprises
QIANJI is a comprehensive industrial and trade enterprise. Our main business is to manufacture and produce relays, including power relays, PCB relays, solid-state relays, automotive relays, and more than 50 types of relays. We are not an agency company, but factory self sold. We will offer you the most favorable price and can also provide you with various types of services, such as customized icons, casings, logos, voltage values, and more.
We have professional business personnel, each with rich experience in foreign trade exchanges. We can handle related affairs very well, and our company also holds relevant meetings to discuss some unresolved issues and handle them reasonably.
Why do we need a relay?
Relays are widely used in various fields such as industry, communication, transportation, healthcare, and home furnishings. In industrial automation, relays are used to control various mechanical equipment, production lines, and processes. In communication systems, relays are used for power management and signal switching. In the transportation system, relays are used to control signal lights, gates, and electric vehicles. In medical equipment, relays are used to monitor and control various instruments and equipment. In home automation, relays are used to control lighting, heating, air conditioning, etc. The use of relays has many advantages in various electrical equipment and systems. Relay provides characteristics such as current and voltage isolation, electrical switching function, signal amplification and conversion, reliability and stability. Meanwhile, the widespread application of relays has made them an important component of modern electrical control and automation fields. Whether in industries, communications, transportation, healthcare, or home furnishings, relays play an indispensable role.
Characteristics of relays
1、 Strong stability Relay is controlled through electromagnetic principles, and its operating principle is to convert a small current into a large current, thereby achieving control of the circuit. Compared to other electrical components, relays have stronger stability. This is because the contact points of the relay are made of special materials and processes, ensuring that they are not prone to oxidation or poor contact during long-term use.
2、 Long service life Relay has a relatively long service life, which can reach the lifespan of hundreds of thousands of switches. This is because the switch mechanical structure of relays is relatively simple, usually composed of mechanical contacts and electromagnets, with a simple and reliable structure. During use, as long as normal operating conditions are maintained, the service life of the relay can be guaranteed.
3、 Strong switching ability The switching ability of relays is stronger than that of ordinary switches. It can control large load currents and voltages, such as high-power motors, transformers, and heaters. This is because the contact points and coils of relays can use different materials and specifications to adapt to different load currents and voltages.
