Reed Relays

Reed relays are a type of electrical relay that works by opening and closing a circuit by means of a reed switch which is operated by an electromagnet. Reed relays are useful for applications that require high-speed switching or very low power operation. They are widely used in industrial automation systems, automotive components, home appliances and consumer electronics.

7203-05-1000 Application Field

The 7203-05-1000 is a type of reed relay designed for high-precision, low-cost switching in industrial, medical, automotive, aerospace, and consumer electronics applications. This relay is capable of switching up to 1A of power at up to 250V, and is designed to switch signals at speeds of up to 10Hz. It is also highly reliable and has an extremely low power consumption.

7203-05-1000 Working Principle

The 7203-05-1000 operates by using an external electromagnet to move a reed switch, which is composed of two metal strips encapsulated within a glass capsule. When an electrical current is applied to the field coil around the capsule, an electromagnetic field is generated, causing the metal strips to move within the capsule. This movement opens or closes the switch, depending on whether an application of current has taken place.

Once the current is removed, the reed switch will return to its original state and the contacts will be reconnected. This entire process happens in less than 1ms, making the 7203-05-1000 suitable for high-speed applications. Additionally, since it uses less than 1mA of current when activated, the 7203-05-1000 is more power efficient than other types of relays.

Conclusion

The 7203-05-1000 is an example of a reed relay, which is a type of electrical switch that utilizes a reed switch that is activated by an electromagnet. This reed relay has a high-precision, low-cost design and is capable of switching up to 1A of power at up to 250V, while operating at speeds up to 10Hz. Additionally, it consumes very little power, making it an ideal choice for low-power applications.
