Introduction

MLX92232LUA-AAA-002-SP is a magnetic switch belonging to the family of magnetic sensors, also known as a solid state switch. Using a hall effect principle, these switches provide contactless switching of electronic circuits through the presence of a determined magnetic field. The MLX92232LUA-AAA-002-SP in particular consists of a robust, sealed plastic housing, two Hall sensors, one for the outer magnet and one for the inner, and a magnetically shielded ASIC IC mounted on the bottom of the housing.

Application Fields

The MLX92232LUA-AAA-002-SP is primarily used in automotive and industrial applications, such as automotive door locks, safety systems, and industrial control and monitoring systems. This switch is also ideal for use in harsh environments, thanks to its robust and tamper-proof sealed plastic housing.Other common applications include detecting the position of engine parts and transmitting signals for controlling the fuel injection system and the ignition system. The switch is also used in medical devices, where a contactless operation is imperative for safety and hygiene.

Working Principle

The MLX92232LUA-AAA-002-SP works on the principle of a Hall effect switch. The switch has two components – the Hall IC and the magnet. The Hall IC is a small integrated circuit or IC, with two tiny metal plates, one embedded in its silicon board, the other one placed in its cover. This IC is responsible for sensing the magnetic field, and then sending a signal. The magnet is composed of two poles, one stronger and one weaker. When the intense pole of the magnet approaches the Hall IC, a strong magnetic field is generated which causes a reaction in the IC and hence a signal is sent. This signal can be used to control any device, depending on the application.

Conclusion

MLX92232LUA-AAA-002-SP is a solid state switch commonly used in automotive and industrial applications. Thanks to its robust, environmentally sealed plastic housing, it is ideal for harsh environments. It works based on the Hall effect, meaning that when a magnet is near the IC, an electrical signal is sent. In this way, the MLX92232LUA-AAA-002-SP magnetic sensor switch is able to provide reliable and contactless switching of electronic circuits.
