AD205-00E Application Field and Working Principle

The AD205-00E, manufactured by American Magnetics, Inc., is a solid-state, reed switch that makes use of a much smaller electrical current to turn the switch on and off. Also known as Hall effect switch, this device makes use of the phenomenon of induced magnetic fields in order to tell when the switch is "open" or "closed".

General Overview of the AD205-00E

The AD205-00E is commonly used in a variety of applications, such as automotive, building automation, industrial automation, medical equipment, robotics, and more. It is typically operated with DC or AC voltages ranging from 9V-250V, and boasts an operating temperature range of -25°C to +80°C. This switch also offers an extended contact life of up to 200,000 cycles. It is RoHS compliant and UL listed.

Applications

The AD205-00E is a versatile device that can be used in a variety of applications. It is commonly used to detect the presence of an object or detect the position of a rotating object. This device is often used in automotive and industrial automation applications to detect the position and/or movement of a particular object, such as a door, window, valve, or any other device requiring positional sensing. Additionally, it can be used for applications such as RPM sensing, proximity sensing, speed sensing, and linear motion sensing.

Working Principle

The basic working principle of the AD205-00E is as follows. Inside the device is a set of reed switches, which are made of two ferromagnetic cores surrounded by a thin piece of plastic or glass. When an external magnetic field is applied to the cores, the reeds become magnetized and the switch is closed. When the magnetic field is removed, the reeds become demagnetized and the switch is opened. This switch can also be operated with an external DC or AC voltage, in which case the external voltage must be higher than the rated voltage of the device in order to turn it on.

Conclusion

The AD205-00E is a handy device for a variety of applications, owing to its small size, simple operation, and extended contact life of up to 200,000 cycles. With a range of capabilities such as RPM sensing, proximity sensing, and linear motion sensing, the AD205-00E proves to be a very capable solid-state switch for any project requiring magnetic sensing. Additionally, it\'s an efficient and cost effective device that\'s RoHS compliant and UL listed, making it the perfect choice for even the most demanding applications.
