Magnetic sensors are components which are based on the principles of magnetism and are used for detection, control, sensing, and motion-control applications. Magnetic sensor switches (solid state) detect changes that occur in or around the object on which the switch is used. Among them, MLX92215LSE-AAA-000-SP is a widely applied type of magnetic sensor switch.

Application Field

MLX92215LSE-AAA-000-SP magnetic sensor switch is mainly used in the fields of digital encoding and positioning, and is especially suitable for use in applications such as rotating angle encoding and transmitting systems, and automation systems which require high accuracy and long-term stability.

This magnetic switch is ideal for applications in which accuracy and reliability are essential like robotics, defense, and aerospace systems. Furthermore, due to its high immunity to external interference caused by temperature and voltage changes, MLX92215LSE-AAA-000-SP is often used in automotive, security, and consumer electronics.

Working Principle

When a permanent magnet is close to the MLX92215LSE-AAA-000-SP switch, it activates the magnetorheological (MR) effect, which produces a magnetic field in the switch’s sensing area. When any part of the switch’s miniature package enters the magnet’s magnetic field, the sensor perceives the signal that causes it to switch accordingly. The sensor switch changes its state from inactive (HIGH) to active (LOW) when the magnetic field is below or above the built-in threshold level, and will maintain that state until the magnetic field changes again.

Moreover, depending on the magnetic field applied, the sensor switch can also be used to detect the rotary angle of the magnet, thus enabling its use in digital encoding and positioning applications. Furthermore, with its high insulation resistance, it provides stability to mechanical adjustments, meaning that the positions of the switch is maintained even after repeated turning and vibration.
