Working of reed switch

Intruder alarms and model railroads often use them too. Photo: A typical reed switch (a Comus RI-23). Find out how they work and which magnets can be used with them.

The Reed Switch is the core element in Reed Sensors, Level Sensors and Reed Relays. A magnetic contact switch consisting of two ferromagnetic blades are herm.

Operating the magnetic reed switch.

Although every application cannot be listed here, the most widely used ones are explained in .

Once the magnet is pulled away from the switch, the reed switch will go back to its original position. Reed switches Animation : Reed switch Working Principle. Working of Reed Switch explained with the help of images of internal parts like ferromagnetic connecting leads, glass capsule, etc. Read more about how Reed Switch works, operating principle and mechanism. A reed switch consists of two or three metal reed contacts.

REED SWITCH WORKING AND MECHANISM IN AUTOMATION INDUSTRIES. Basic operation of reed switches. Reed Switches , SMD Reed Switches , Reed Sensors, Level Sensors, Hall Sensors, Floats. Common applications of reed switches are in reed relays, automotive sensors, security systems, robotics, toys and games. This simple device has many uses.

In this article, we will be discussing about the . Application Note: Reed Switch and Reed Sensor Activation. When measuring discrete levels of liquids such as automobile brake flui reed switch technology is simple, inexpensive and reliable. When the magnetic field is remove the reeds separate and the switch opens. In addition, reed switches allow for the simple customization of sensitivities and other application -specific requirements. Industrial AC and DC motors and drives incorporate reed switches into their product designs.

These help in controlling load and monitoring speed. They are also used to help sense rotor position and signal proper drive operation. Compared to other relay technologies, reed relays have the advantages of hermetically sealed contacts, low coil power, fast operation , and small size.

However, as with any technology, there are various aspects to consider. Search Coils to allow you to achieve your application .
