Melexis MLX90642 Thermal IR Sensors

Introduction

The Melexis MLX90642 Thermal Infrared (IR) Sensors are advanced thermal imaging devices designed to provide precise temperature measurements and detailed thermal images. With a fully calibrated 32x24 pixel array, these sensors are ideal for various applications that require accurate thermal mapping.

Part Description

The MLX90642 sensors feature a 32x24 pixel thermal imaging array, offering a total of 768 Far-Infrared (FIR) pixels. This allows for the generation of detailed thermal images and accurate temperature readings of the environment. The sensors utilize a global shutter readout, ensuring that all pixels capture data simultaneously, which minimizes motion artifacts and provides consistent thermal imaging. They come with two field of view (FoV) options: 45°x35° and 110°x75°, and support a programmable refresh rate ranging from 2Hz to 16Hz. The sensors are factory calibrated, easy to integrate, and operate within a temperature range of -40°C to 85°C ambient and -40°C to 260°C for objects.
