Magnetic sensors are found in a wide range of applications that can be found in everyday life and in industrial, automotive, and medical applications. They all work by detecting changes in an external magnetic field and the AH276UZ4-AG1 is one such sensor. This sensor is a solid state magnetic switch which can be used in applications where contact switching is not suitable, such as high voltage or high current applications.

Description

The AH276UZ4-AG1 can act both as a normally open and normally closed push button switch. It is a self-contained, low power, magnetic switch designed for use in various industrial, consumer, and automotive applications. It has an operating current of less than 30 mA and a DC interruption rating of 0.25A at 36V. The contact arrangement of the switch can be designed to suit the application, with either normally closed or normally open circuits suitable.

Working Principle

The AH276UZ4-AG1 utilizes the Hall Effect principle to detect changes in an external magnetic field. The AH276UZ4-AG1 consists of a Hall Effect element, a magnet, and an integrated circuit containing the logic that controls the switching. When a magnet is brought in close proximity to the Hall Effect element, the magnetic field induces a current in the element which is then processed by the integrated circuit to switch the output.

The switch has an adjustable set point which allows the user to set the value of the magnetic field at which the switch will be triggered. This allows the user to adjust the sensitivity of the switch so that it will only respond to the magnetic field of the specific magnet it is designed to detect.

Applications

The AH276UZ4-AG1 is suitable for a variety of indoor and outdoor applications where contact switching is not suitable. This makes it ideal for applications where it is not practical to have contacts such as high voltage or high current applications. The switch is also suitable for medical applications, as it gives a precise indication when the switch is triggered.

The AH276UZ4-AG1 can be used in security systems, to detect when a door is opened, or in high-speed automation systems as a limit switch to detect the presence of an object. It is also suitable for use with water again systems, as it can be used to detect when the level of water reaches a certain point. The switch can also be used in robotics, to detect when a robot has moved to a certain point.

Conclusion

The AH276UZ4-AG1 is a solid state magnetic switch which can be used in applications where contact switching is not suitable. It utilizes the Hall Effect principle to detect changes in an external magnetic field, and has an adjustable set point which allows the user to set the sensitivity of the switch. The switch is suitable for a variety of applications such as security systems, medical devices, and high-speed automation systems, making it a versatile and reliable sensing solution.
