Introduction
The A3280LUA is a magnetic sensor switch designed for use in applications where large amounts of power, currents or voltage must be switched. The A3280LUA is a solid state device that uses a Hall Effect to detect changes in the magnetic field. The device is capable of switching currents up to 30 amperes and/or voltages up to 15 Dozen. The A3280LUA also features a fast response time, low on resistance, low current drive capability, and exceptional maximum operating temperature.

Application Fields
The A3280LUA is commonly used in a variety of different industrial and commercial applications. These include motor control applications, position feedback, current limiting circuits, and safety circuits. In motor control applications, the A3280LUA can be used to switch currents on and off, thereby controlling the amount of power delivered to the motor. In position feedback applications, the A3280LUA can be used to provide feedback regarding the motor position. In current limiting circuits, the A3280LUA can be used to limit the amount of current supplied to the circuit. Finally, in safety circuits, the A3280LUA can be used to switch power off in the event of a dangerous situation.

Working Principle
The A3280LUA uses a Hall Effect to detect changes in the magnetic field. The device works by sensing the change in the magnetic field around a ferromagnetic target. The device is composed of a permanent magnet core surrounded by a ferromagnetic shield. When the ferromagnetic target enters the magnetic field created by the core, it will generate a voltage. This voltage will be sensed by the Hall Effect and used to switch on and off the current or voltage supplied to the device. The A3280LUA also features a hysteresis curve that will allow for a range of voltage levels be used to switch the device on and off.

Conclusion
The A3280LUA is a magnetic sensor switch designed for use in applications where large amounts of power, currents or voltage must be switched. The device is capable switch currents up to 30 amperes and voltages up to 15 dozen. The A3280LUA is commonly used in a variety of different industrial and commercial applications such as motor control, position feedback, current limiting circuits, and safety circuits. The device works by sensing the change in the magnetic field around a ferromagnetic target. The A3280LUA also has a hysteresis curve that allows for a range of voltage levels to be used to switch the device on and off.
