The FF3-21-AC-03 module is one type of magnetic sensor - a device used to measure and detect the presence of a magnetic field in order to determine a position, proximity, speed or other attribute. It is a part of a larger family of sensors used in countless industrial and consumer-level applications, typically measuring things like linear distance, including level, air speed, angular position and much more.

This particular type of magnetic sensor is a Inductive Proximity Switch (IProx). It uses a metal foil wrapped coil to detect the presence of a metallic object within the specified range, usually within a few centimeters. The sensing range is determined by the thickness of the coil used, as thicker wire provides a larger sensing field.

The module consists of the IProx, a processor, and an output device, all packaged in a tiny case measuring 0.67" x 0.43" x 0.27". It is designed to be low power, mountable, and easy to use. It is based on Hall effect technology, which means it is resistant to shock and vibration, making it perfect for industrial applications. The processor converts the signal from the IProx into a digital output, which can be used with various outputs to control devices, such as relays, motors, solenoids, and LED\'s.

The FF3-21-AC-03 is a reliable and robust magnet switch with a variety of uses. It is commonly used to measure linear distance in industrial settings, such as monitoring the level of a tank or container, as well as for air speed measurement. It is also used for more complex tasks, such as controlling the position of a robotic arm or monitoring rotational speed.

Furthermore, the FF3-21-AC-03 can be used in a variety of consumer-level applications. It is often used as part of a home automation device, such as for a door or window security system. It can also be used as part of a creative DIY project, such as a model train set or a remote controlled device.

In conclusion, the FF3-21-AC-03 modular magnetic sensor is a reliable and robust device for measuring linear distance and air speed. It can be used in industrial and consumer applications, both simple and complex. The processor and output device make it easy to use, and the compact design makes it perfect for projects of all sizes.
