IntroductionMagnetic Sensors - Switches (Solid State) is an important component in a wide range of electronic systems. In these components, a magnetic field is used to switch the device to a different state. One such type of device is the AD120-02E, a Hall-effect switch with magnetic field sensing capabilities. This device uses a Hall-effect, or magnetoresistor, to detect the presence of a magnetic field. When the magnetic field is detected, the output signal is switched from high to low or vice versa. This article will discuss the application field and working principle of the AD120-02E.Application FieldThe AD120-02E is primarily used in automotive applications, such as engine control to protect against overloading. It can also be used in industrial control systems, for example, to detect the presence of hazardous objects. Additionally, it can be used in medical applications to monitor the presence of objects such as implants or pacemakers. Finally, it can be used in consumer electronics, as an input device, such as a switch or a knob.Working PrincipleThe working principle of the AD120-02E is based on a Hall-effect, or magnetoresistor. This device is made up of a special material that responds to the presence of a magnetic field. When a magnetic field is present, the hall effect causes the material to become less conductive, which causes a change in the current flow. The change in the current flow is then detected by the AD120-02E, which causes the output signal to switch from high to low or vice versa. This output signal can then be used to control the device\'s state.ConclusionIn conclusion, the AD120-02E is a Hall-effect switch with magnetic field sensing capabilities. It is mainly used in automotive, industrial, medical, and consumer electronics applications, and its working principle is based on a Hall-effect. This device can be used to protect against overloading, detect hazardous objects, monitor implants, or serve as an input device.
