Magnetic sensors, also known as switches, are used in a variety of applications where it is important to detect the presence or the absence of a magnetic field. The MLX92231LSE-AAA-032-RE is a solid-state magnetic sensor switch that uses a Hall effect sensing element. This article provides information about the application field and working principle of the MLX92231LSE-AAA-032-RE.

Application Field

The MLX92231LSE-AAA-032-RE is designed for applications where space is limited and the ability to detect low intensity magnetic fields is desirable. It is suitable for applications such as industrial motors, home appliances, and building automation systems. This device is also suitable for a variety of non-contact position sensing applications.

The MLX92231LSE-AAA-032-RE provides reliable open-loop non-contact Hall-effect switching, ideal for applications that require a low switching frequency. This device is capable of reliably detecting even weak DC magnetic fields and is stable over temperature and operating life.

This device is packed in a RoHS compliant, hermetically-sealed SIP (8 pins) package. It has an operating temperature range of -10°C to 125°C. The MLX92231LSE-AAA-032-RE is a low-power device, operating on a supply voltage of 4.5V to 24V.

Working Principle

Magnetic sensors are devices that use the Hall effect to detect the presence of a magnetic field. The Hall effect is a phenomenon where the voltage field across a semiconductor is altered when it is exposed to a magnetic field.

The MLX92231LSE-AAA-032-RE uses an advanced proprietary Hall sensing element to detect and measure weak DC magnetic fields. The Hall element is mounted on a thermally insulated package for minimal temperature drift and stable operation. The device is configured to operate as an open-loop switching output, which is ideal for applications that require a low switching frequency.

The MLX92231LSE-AAA-032-RE operates with a supply voltage of 4.5V to 24V and is capable of detecting magnetic fields from 0 to ±30 mT (millitesla) depending on the bias voltage. The output will change state when a magnetic field crosses the switch threshold threshold. Once the output has changed state, it will remain in that state as long as the magnetic field is present. Once the magnetic field is removed, the output will reset to its default state.

Conclusion

The MLX92231LSE-AAA-032-RE is a solid-state magnetic sensor switch designed for space-constrained and low-level magnetic field detection applications. It uses a proprietary Hall effect sensing element to detect weak DC magnetic fields with minimal temperature drift. This device operates with a supply voltage of 4.5V to 24V and is capable of detecting magnetic fields from 0 to ±30 mT. With its stable operation over temperature and life, the MLX92231LSE-AAA-032-RE is ideal for applications such as building automation systems and industrial motors.
