Reed Relays

Reed relays are discrete switches that are used to connect two components in an electronic circuit. The 8L61-12-111 is a reed relay designed specifically for low-voltage applications and it works on the principle of a ferromagnetic core. This type of reed relay is constructed using a thin, high-strength glass tube as the core. Inside the glass tube, a coiled copper wire is wrapped around the ferromagnetic core, which is connected to a switch mechanism. When the switch is activated, the ferromagnetic core moves inside the glass tube and creates a magnetic field that is strong enough to attract the metal contacts and initiate the switching action.

Application Field

The 8L61-12-111 is suitable for low-voltage applications as it operates at an operating voltage of 6 to 36 volts. It can be used to control low-voltage appliances such as: refrigerators, washing machines, air conditioners, and other appliances. Additionally, this type of reed relay can be used in industrial control systems, such as motor controls, door locks, and contactors.

Working Principle

The 8L61-12-111 operates on the principle of a ferromagnetic core. When the switch is activated, the ferromagnetic core is moved inside the glass tube, creating a magnetic field that attracts the metal contacts. When the metal contacts come into contact with each other, they form an electrical connection and activate the circuit. One of the benefits of using this type of relay is that it has a relatively small size and low power consumption, making it suitable for small, low-voltage applications.

Advantages

The 8L61-12-111 has several advantages when compared to other types of relays. These include a small size, low power consumption, easy installation, and high reliability. Additionally, the reed relay has a high switching speed, making it suitable for use in industrial and commercial applications. It is also extremely resistant to corrosion and vibration, and has a long operational life.

Disadvantages

Although the 8L61-12-111 has several advantages, there are some drawbacks to consider. One of the main drawbacks is that it can only be used in low-voltage applications. Additionally, the switching speed is limited by the magnetic properties of the core, so it may not be suitable for applications that require faster switching speed. Finally, the relay is not suitable for use in high temperature environments due to the glass tube.

Conclusion

The 8L61-12-111 is a low-voltage reed relay designed specifically for low-voltage applications. It has several advantages such as a small size, low power consumption, and easy installation. Additionally, it has a high switching speed and is resistant to corrosion and vibration. However, it is only suitable for low-voltage applications and its switching speed is limited by the magnetic properties of the core. Despite these drawbacks, the 8L61-12-111 is still a great choice for low-voltage applications.
