SM24ML1S18 Datasheet/PDFThe SM24ML1S18 is a small and reliable magneto-resistive switch designed to detect movement for presence and orientation coordination. It outputs a linear, digital, high impedance signal. This type of switch is widely used in a variety of applications such as linear motor control, robotics, equipment monitoring, and many others.
The SM24ML1S18 uses a proprietary pole profile combined with a well-defined sealed air gap to detect rotational movement in the range of ±5 degrees. The switch can rotate up to two revolutions, which increases its angular accuracy and allows for more accurate angle control during high-speed applications. The switch also features a low power consumption and a rugged construction to withstand vibration and shock.
Its working principle is based on the Hall Effect. The Hall Effect is a fundamental physical phenomenon, that produces an electric field which is proportional to the magnetic field. The SM24ML1S18 uses a magnetic field to detect the rotational movement of the pole. As the pole rotates, its magnetic field interacts with the switch’s magnetic core and generates a digital signal which can then be processed and interpreted depending on the application.
As a magneto-resistive switch, the SM24ML1S18 has been designed for a multitude of different applications. In manufacturing, it can be used to monitor and control the position of industrial motors during automated production. In transportation, it can be used to detect tilt angles in applications such as trains and ships. In robotics, the switch is often used to measure the orientation of robots, helping them to navigate in their environment and avoid obstacles.
The SM24ML1S18 has also found its way into other applications, such as virtual reality devices, gaming consoles and 3D printers, where it is used to detect the movement of objects in three-dimensional space. This helps to create a more realistic and immersive user experience, as the objects move with more precise control.
The SM24ML1S18 is a great example of how magnetic fields can be used to detect movement, and its versatile design make it suitable for a multitude of different applications. Its low power consumption, robust construction and accurate signal detection make it an ideal choice for a wide range of motion control applications.
