SBR405SD

Reed relays are among the most commonly used components in various types of electronic circuits. The SBR405SD is a series of reed relays that have been designed to be highly reliable and to stand up to the rigors of everyday use. This article will explain the application field and working principle of the SBR405SD.

Application Field of the SBR405SD

The SBR405SD is a reed relay designed for use in harsh environments, such as those found in industrial settings. It is capable of switching up to 10A of current and operating at a wide range of temperatures. It is also certified for operation in hazardous locations, making it ideal for applications such as motor control, AC and DC switching, switching motors in hazardous locations, and solenoid control. In addition, the SBR405SD is compatible with a wide range of automotive, medical, and military applications.

Working Principle of the SBR405SD

At the heart of the SBR405SD is a tightly sealed glass chamber containing two contacts and a magnetically responsive reed switch. When a current is passed through the contacts, the reed switch is activated and allows the current to flow from one contact to the other. When the current is stopped, the reed switch deactivates and prevents any further current from passing through.

The SBR405SD also has a low-level magnetic reset feature, which when activated, prevents any further current from passing through the contacts. This allows the relay to reset itself without requiring external input, such as a control signal. This reset feature also ensures that the contacts remain in their correct positions when power is removed.

The SBR405SD has an extended operating life due to its robust construction. Its contacts are formed from a gold-plated and silver alloy, which prevents oxidation and offers superior durability. The reed switch is also designed to withstand extreme temperatures and can operate both in dry and wet environments.

The SBR405SD is also highly resistant to vibration, making it ideal for use in high-frequency applications. The relay is also equipped with a thermal ammeter to protect against thermal overloads.

Conclusion

The SBR405SD is an incredibly robust reed relay, designed to stand up to even the harshest of environments. Its wide range of capabilities and extended operating life make it ideal for a wide range of applications, ranging from industrial motor control to automotive and military applications. Its low-level magnetic reset feature ensures that the contacts remain in their correct positions when power is removed, while its thermal ammeter protects against thermal overloads. The SBR405SD is a reliable and versatile solution for any application that requires a reed relay.
