Reed Relays

A reed relay is a type of electrical switch that uses a wetted reed contact, protected in a glass tube, to make and break an electrical circuit. The switching action is as a result of a reed contact being made/broken due to a controlled magnetic field. The reed contact is a thin length of metal that requires very low power to be actuated, so it can be controlled using very small current. Sealed reed relays do not require a continuous power supply for their operation, allowing them to be actuated with very short pulses. This can be very energy efficient and also allow for long lasting relay applications.

7304-12-1100 is a type of reed relay that has a distinctive structure and electromagnetic properties. It is a latching reed relay with short-form contacts and coil winding. It depends on the electromagnetic field produced by the coils to open and close its switch, offering many advantages over other types of relays.

Application Field

The 7304-12-1100 reed relay is mainly used in electricity control systems and other applications with low power requirements. It also has suitable frequency characteristic for applications with high frequency ac signal. It is suitable for automatic control circuits, computers, industry, instrumentation, communication systems as well as automatic electric heating and electronic consumer goods.

Working Principle

The 7304-12-1100 reed relay employs a wetted reed contact that is encased in glass. This contact is responsive to a controlled magnetic field generated by a coil around the reed contact. When this coil is energized with an electric current, a magnetic field is produced, and this generates a force attracting the reed contact to the coil. The motion of the reed contact causes it to come into contact with two other contacts and thus makes an electrical circuit. When the current is removed from the coil, the reed contact returns to its original position, and the contacts are released, breaking the circuit.

Advantage

The 7304-12-1100 reed relay offers several advantages over other types of relays. One of the major ones is that it does not require a continuous power supply for its operation. This means that the current drawn by the relay remains low for most of the time, which allows for it to be used in energy efficient applications. Also the contact closure transition is very fast, which makes it suitable for use in a variety of applications. Additionally, the low power requirements of the reed relay allow for more flexible designs and smaller packages, both of which save space for larger projects.

Conclusion

The 7304-12-1100 reed relay is a type of low power switch that can be used in a variety of applications. It utilizes a wetted reed contact encased in glass to make and break electrical circuits. It is primarily used in electricity control systems and other applications with low power requirements, and its particular design makes it suitable for many other uses. Its major advantage is that it does not require a continuous power supply for its operation.
