AD522-00E Magnetic Sensors - Switches (Solid State)

The AD522-00E is an integrated magnetic sensor designed for a wide range of applications in both commercial and industrial environments. The device is designed to detect magnetic fields and triggers its output accordingly. It provides accurate detection of fields from both permanent magnets and electromagnets, as well as some ferromagnetic materials. The AD522-00E is available in a wide variety of sizes, configurations, and pin arrangements for easy integration into magnetic switch circuits.The AD522-00E features a low-cost alternative to typical mechanical switches, which have been used since long to detect and operate in the presence of a magnetic field. While the AD522-00E may have a slightly higher initial cost, the long-term reliability and durability advantages of a solid state device can make it a better choice in many applications.The AD522-00E utilizes Hall effect technology to accurately detect the presence of a magnetic field. The Hall effect is a phenomenon exhibited by certain materials when an electrical current is passed through it. When a magnetic field is present, the current-carrying electrons in the material are “pushed” or “pulled” in one direction or the other. The shifts in the positions of the electrons in the Hall effect materials, found in the chip of the AD522-00E, generate an output signal.The AD522-00E’s Hall effect circuitry features selectable gain settings, which enable users to set the sensitivity to any given application. The output logic is also programmable, allowing for setup so that it can be triggered by either a low or a high magnetic field. The device’s output is a digital signal, which is capable of sinking or sourcing current on the order of one mA. The device is both RoHS- and REACH-compliant, making it a popular choice for applications requiring environmental compliance.The AD522-00E provides reliable sensing operation in temperatures ranging from -40 to 85 degrees C, meaning it can be used in the most extreme conditions with little to no impact on performance. The chip’s built-in protection circuitry significantly reduces the risk of damage from electrostatic discharge and overvoltage, making it a safe choice for sensitive applications. Additionally, the device is RoHS, lead-free, and halogen-free compliant, making it suitable for most manufacturing processes.The AD522-00E is an ideal solution for applications that require reliable magnetic sensing capabilities, with superior durability, reliability, and accuracy. Its miniature size and low-power operation make it a great choice for space-constrained and energy-limited applications. The device’s programmable gain settings enable users to optimize it for their specific application conditions, and the built-in protection circuitry further reduces the risk of damages from overvoltages and spikes.
