MLX75031CLQ-AAA-000-TU is a multi-standard, ultra-low-power infrared proximity sensor from Melexis. This series of sensors is designed to work with Proximity Switch and Reflective Object Detection systems. MLX75031CLQ-AAA-000-TU has several features that make it particularly suitable for these applications.

Application Field

The primary applications of MLX75031CLQ-AAA-000-TU are in Proximity Switch and Reflective Object Detection systems. The sensor can detect objects in close proximity and at a distance of up to 30 cm. It has a wide operating temperature range, from -40° C to +85° C, and is RoHS compliant. The robust packaging is suited for industrial and commercial environments.

The MLX75031CLQ-AAA-000-TU is suitable for the implementation of contactless switching applications. It enables the implementation of such systems in harsh industrial environments, and its wide operating temperature range allows for use in temperature-sensitive applications. Additionally, this device is equipped with several fail-safe features, such as power-on reset, over-current protection, and under-voltage lockout, that ensure reliable operation even in unpredictable conditions.

The device can also be used for object detection applications. It offers an adjustable detection threshold which allows for greater accuracy in detecting objects. The adjustable Digital Filter option can reduce false triggering due to external sources, such as fluorescent lighting, and it can detect objects up to 30 cm away. Finally, the integrated self-calibration feature ensures the accuracy of measurements over time.

Working Principle

The MLX75031CLQ-AAA-000-TU is an integrated infrared proximity sensing device. The sensor utilizes an infrared transmitter-receiver pair in order to detect objects in close proximity or at a distance. The transmitter emits an IR signal which is refracted off of objects and detected by the receiver. The signal is then processed by the device’s circuitry, and it is output as a low or high logic level depending on the relative proximity of the object to the device.

The operation of the MLX75031CLQ-AAA-000-TU is based on two options. The first option is the standard proximity option, which allows for detection of objects up to 30 cm away. The second option is the reflectance option, which uses a beam-break signal to detect objects up to 15 cm away. The device also features an adjustable digital filter, which allows for reduction of false triggering due to external sources.

The device includes an integrated auto-calibration feature, which allows for accurate measurements over time. This feature compensates for the effects of aging, environmental changes and temperature variations, to ensure that the output of the sensor is reliable and accurate. Additionally, the device features a power-on reset, an over-current protection and an under-voltage lockout that ensure reliable operation even in unpredictable conditions.

The MLX75031CLQ-AAA-000-TU is a robust, low-power infrared proximity sensor that is ideally suited for object sensors and contactless switching applications. It can detect objects at distances up to 30 cm, offers an adjustable digital filter, and incorporates a self-calibration feature that ensures accuracy over time. The series is RoHS compliant and is certified for operation in industrial and commercial environments.
