Melexis announced a new version of its far-infrared (FIR) thermal sensor array. The new device has a lower thermal noise compared to the current MLX90640, an increased refresh rate of 64 Hz and an elevated operating temperature up to 125°C.
 
This latest sensing technology allows for simplified integration of temperature measurement into applications that enhance safety, efficiency, convenience, especially in harsh thermal conditions.
 
The new MLX90641 is a small 16 x 12 pixel IR array housed in an industry standard 4-lead TO39 package that is able to accurately measure temperatures in the range -40°C to +300°C. The factory-calibrated devices ensure the accuracy of 1°C in typical measurement conditions.
 
The extended temperature range opens up multiple new applications, and the new MLX90641 is expected to be suited to applications in the world of cooking, such as conventional and microwave ovens, as well as industrial applications such as detection of power electronics overheating and automotive.
 
“The extended temperature range and enhanced thermal stability make this new device even more versatile than earlier devices,” said Joris Roels, marketing manager, temperature sensors.
