Magnetic Sensors - Switches (Solid State) are often used in a variety of applications to detect small amounts of movement, such as a switch opening or closing. AD322-00E is one such device designed for such use. This particular switch is a Hall effect switch with an excellent operating temperature range of -40°C to +85°C. It has a wide operating voltage range of 1.8V to 16V and can be used in applications up to 30V.

In operation, the switch is powered up and the switching point is set with a full range trimming pot. The magnet is then placed near the switch at a distance that depends on the sensor model. This distance should not exceed the specified “Sensitivity Distance” of the switch. When the sensing magnet is moved across the sensing area, the switch will detect the movement and the output will toggle accordingly. This is especially useful for applications where a small tactile switch would not be suitable.

The AD322-00E has several features such as circuitry protection against high level transients, protection against polarity reversal, and an on-board Schmitt Trigger on the output. This makes the switch highly suitable for a variety of applications including controlling switching cam position, providing feedback on motor position, and detecting the opening and closing of motors, valves, and other devices.

The switch is also capable of taking pulse signals and outputting them as digital signals. This makes it suitable for use in applications that require very fast frequency response, such as in high speed counter circuits. This device can also be used to detect small micro-voltage and current changes which are perfect for applications such as in occupancy sensors and security systems.

For smaller applications requiring less complexity, the AD322-00E has a wide operating temperature range and an adjustable hysteresis that is suitable for controlling low power devices that require a low detection current. It also has a low power consumption and no external power supply required which makes the switch not just energy efficient but also cost effective.

This particular Hall effect switch is extremely reliable and accurate, making it suitable for many types of applications. It is very easy to install and use and can be used in a variety of applications. It is important to remember to use the specified “Sensitivity Distance” when placing the switch near the magnet in order to ensure receive the most reliable output.
