Reed Relays

Reed relays are some of the oldest and most reliable types of relays in the world. Along with being used in everyday applications such as controlling streetlights and automated factory production lines, these relays also play a vital role in sensitive computer and military applications. Though the concept behind reed relays has existed for over a century, advancements in technology have improved the performance of these devices and have introduced features that make them even more reliable and useful than ever before. This article will discuss the 7122-24-1010 application field and working principles, and how this particular reed relay differs from standard models.

What is a Reed Relay?

A reed relay is an electrical switch consisting of a coil (armature), an iron core, and several reeds. When the coil is energized, the iron core creates a magnetic field which causes the reeds to move and make contact with each other. This creates a complete circuit, allowing an electrical current to pass through. Reed relays are known for their reliability and durability, and because they are not all that complicated, they tend to have a relatively low cost.

7122-24-1010 Application Field and Working Principles

The 7122-24-1010 reed relay is most commonly found in communication, instrumentation, and industrial applications. It is a two-pole, double-throw switch which can be activated from either side of the coil. The contact rating of this device is 250 V AC/DC, 0.5A, with an insulation resistance of 105M Ω minimum. When it comes to operation, the 7122-24-1010 typically employs an external circuit to supply the necessary energy to drive the switch. When energized, the coil forces the iron core to create a strong magnetic field. This causes the reeds to move and make contact with each other, completing the circuit. The switch will remain in this position until the circuit is de-energized. Because of its design, the 7122-24-1010 has several advantages over standard reed relays. For starters, its two-pole, double-throw switch can be activated from either side of the coil. This means that there is no need to change the polarity of the circuit in order to switch the relay from one state to the other. Additionally, the insulation resistance of 105M Ω minimum ensures that signal loss due to electromagnetic interference is reduced significantly.

Conclusion

The 7122-24-1010 reed relay is a reliable, cost-effective, and easy-to-use switch designed for communication, instrumentation, and industrial applications. It has several advantages over standard reed relays, including two-pole, double-throw switchability, and reduced signal loss due to higher insulation resistance. This makes the 7122-24-1010 an ideal choice for applications where signal integrity is of critical importance.
