Reed relays are electromechanical switches which use an electromagnet to move contacts from an off position to an on position. They are used in a variety of applications, including switch control, amplifier bypassing, logic circuits, and signal routing. The SHV12-1A85-78L4K is one example of a reed relay used in these types of applications. This article will discuss the application field and working principle of the SHV12-1A85-78L4K reed relay.

Application Field

The SHV12-1A85-78L4K is a general purpose reed relay designed for a variety of switch applications. It can be used in low-current applications, such as controlling switches in home automation systems, or in high-current applications, such as connection switching in welding machines. The relay is also suitable for use in DC and AC circuits, making it a versatile tool for a variety of applications.

In addition to the wide range of applications, the SHV12-1A85-78L4K also provides reliable operation in potentially hazardous environments. It is UL Class 5 Rated, meaning it is safe and suitable for use in hazardous environments where the presence of sparks is a concern. It also has a maximum insulation distance of 8mm, making it suitable for use in systems with high concentrations of electric fields. With these features, the SHV12-1A85-78L4K is suitable for use in a variety of sensitive and potentially hazardous environments.

Working Principle

The SHV12-1A85-78L4K is a magnetic reed relay, meaning it uses an electromagnet to move contacts from an off position to an on position. The relay contains two reeds, which are metal strips suspended within a sealed glass envelope. The reeds are arranged so that when the current is turned on, an electromagnet attracts one reed and causes it to move, shifting the contacts from the off position to the on position. Once the current is turned off, the magnet is no longer supplying power and the reed springs back to its original position, thus switching the contacts back to the off position.

The SHV12-1A85-78L4K is designed to provide reliable operation in a variety of applications. It is rated for a maximum current of 10A, making it suitable for low and high current applications. It also has a maximum insulation distance of 8mm, making it suitable for use in systems with high concentrations of electric fields. In addition, it is suitable for use in DC and AC circuits, making it a versatile choice for a variety of switching applications.

Conclusion

The SHV12-1A85-78L4K is a general purpose reed relay designed for a wide range of applications. It is UL Class 5 Rated, making it suitable for use in potentially hazardous environments. It also has a maximum current rating of 10A and a maximum insulation distance of 8mm, making it suitable for use in systems with high concentrations of electric fields. The SHV12-1A85-78L4K offers reliable operation in a variety of applications due to its design and theirreliability features.
