MLX92231LSE-AAA-009-RE Sensors, Transducers

Application Field and Working Principle of MLX92231LSE-AAA-009-RE

The MLX92231LSE-AAA-009-RE is a sensor-switch component part of the Melexis family of Magnetic Sensors. It is specifically designed to detect the presence of a magnetic field such as the magnetic field created when powered by alternating current or permanent magnetization. When two magnets, one of which is powered, are joined together the MLX92231LSE-AAA-009-RE produces an output signal which, in turn, can be used to trigger certain actions.

Overview

The MLX92231LSE-AAA-009-RE is a 3V low power Hall-effect Magnetic Sensor. It has high sensitivity, high accuracy, wide operating range, and fast switch-off times. It can be used in different temperature range applications like automotive, medical, aviation, marine, domestic appliances, etc. The 3 VDC supply voltage and small footprint makes it ideal for mission-critical and space-constrained applications.

Working Principle

The MLX92231LSE-AAA-009-RE is a three-terminal Hall-effect switch. It works by sensing the magnetic field in the air gap around the device. When the magnetic field is above or below the predetermined threshold, the device will switch an output on or off. The MLX92231LSE-AAA-009-RE has two different outputs, one for each direction of the switch. This allows it to sense magnetic fields from multiple directions.

The MLX92231LSE-AAA-009-RE uses the principle of Hall Effect to sense the presence of a magnetic field. When a current is passed through the device’s internal element, a transverse magnetic field is created which can be detected by the device’s internal Hall-effect transducer. When the magnetic field exceeds the predetermined threshold the output is switched on.

Applications

The MLX92231LSE-AAA-009-RE is suitable for a variety of applications such as proximity detection, repetitive triggering, contactless limit switching, speed detection, angle measuremnt, and magnetic field sensing. It is especially useful for applications that require a small footprint.

The MLX92231LSE-AAA-009-RE can be used in automotive applications such as an engine speed sensor, valve position sensor, door position sensor, and manifold absolute pressure sensor. It can also be used in aviation and marine applications for signal rotational speed, navigation, avionics, and fishing equipment. In addition, this sensor-switch can be used in domestic appliances such as washing machines and fridges, medical applications such as portable oxygen monitors, and in robotics for proximity and limit switch sensing.
