Magnetic Sensors - Switches (Solid State) consist of a permanent magnet, a sensor, and an electrical switch. They are used to detect the proximity of a magnet to a specific target area such as a steel gate, a physical object, or a switch. The AD323-00E is a typical example of magnetic sensor switches.

Application Fields

AD323-00E magnetic sensor switches are designed for applications in a wide range of industries, including robotics, aviation and transportation, manufacturing, aerospace, automotive control, and consumer and medical devices. They are ideal for applications that require reliable, accurate detection of a magnetic field applied within a recommended range.

In the aerospace industry, they can be used to detect the presence of a malfunctioning electrical system, or a critical component at a particular location. The automotive industry is using them to detect the proximity of a key to the driver’s seat, or to detect if the vehicle is reversing. In consumer devices, they are used to detect when a person is approaching a particular location or to detect the orientation of a device. In the medical industry, they are used to detect the presence or absence of a magnetic field and alert the user when a person is getting too close to a dangerous area.

Working principle

AD323-00E magnetic sensor switches work by detecting the presence of a magnetic field using an integrated Hall-effect or magneto-resistance sensor. When a magnetic field is present, the sensor produces a small voltage. This voltage is processed by an internal control circuit and a digital output is generated. Depending on the design of the switch, the output can be used to switch an external load, such as a relay or a motor, or it can be used to sense the presence, absence or orientation of a magnetic field.

The sensitivity of the switch is determined by the strength and position of the magnet used. The sensitivity can be adjusted by using a stronger magnet, moving the magnet closer to the switch, or by using an adjustable internal resistor. The stronger the magnet used, the greater the sensitivity and accuracy of the switch.

AD323-00E magnetic sensor switches have a wide range of operating temperatures, from -40°C to 85°C. They also have a wide operating voltage range, from 1.8V to 5.5V, and a low current consumption, making them ideal for applications in battery-powered devices. The switch also has a reverse current protection feature that prevents a long-lasting current from flowing in the opposite direction.

Conclusion

AD323-00E magnetic sensor switches are designed for applications where reliable and accurate detection of a magnetic field is essential. They use integrated Hall-effect and magneto-resistance sensors to detect a magnetic field and produce a digital output. The switches can be used in a wide range of industries, and offer a wide range of operating temperatures, operating voltage, and current consumption. Furthermore, the sensitivity of the switch can be adjusted by using a stronger magnet, moving the magnet closer to the switch, or adjusting the internal resistor. With these features, AD323-00E magnetic sensor switches are ideal for a wide range of magnetic sensing applications.
