A1120EUA-T Application Field and Working Principle

The A1120EUA-T is a small, cost-effective magnetic sensor switch belonging to the category of Magnetic Sensors - Switches (Solid State) with a variety of application fields and working principles. This type of sensor switch operates using varying magnetic fields. They rely on a “Hall effect” to detect changes in magnetic flux applied to their sensitive region.

Application Fields

The A1120EUA-T can be used for a variety of applications, such as door contacts, flow monitoring, surge protection, and current sensing. It is also very beneficial in automotive and motor control applications. For automotive applications, the A1120EUA-T can be used for speed measurement, and various automotive control systems and systems in which a wheel bearing is needed to be monitored.

In addition, this type of sensor is also often used in several general-purpose motor control applications such as automatic garage door openers, home appliances, and air conditioning systems. This type of sensor can also be used for medical applications like blood pressure monitoring, or to measure the vibration of a machine under test.

Working Principle

This type of magnetic sensor switch functions by relying on the magnetic field created by current flow in a nearby wire. When a current is passed through a wire, a field is created around it. The Hall effect sensor contains a set of Hall plate elements that are sensitive to the nearby magnetic field. When a magnetic field is applied to the sensor, the direction and strength of the magnetic field will cause an electrical current to be generated in the Hall plate. This signal is then used to produce an output signal.

In the case of the A1120EUA-T, the output signal has a maximum output of 250 mV/V and can be used to detect changes in the ambient magnetic field, acting as an open/closed switch. This feature makes the A1120EUA-T ideal for detecting changes in the magnetic field in a variety of applications. Furthermore, this type of sensor has a maximum operating temperature of 150°C and is resistant to shock-induced frequencies.

Conclusion

The A1120EUA-T belongs to the category of Magnetic Sensors - Switches (Solid State). This type of sensor switch is extremely versatile in a number of applications such as door contacts, flow monitoring, surge protection, and current sensing.
