Melexis Launches High Operating Temperature Thermal Sensor Array

Melexis announces a new version of its FIR thermal sensor array with lower thermal noise compared to the current MLX90640, an increased refresh rate of 64 Hz and an elevated operating temperature up to 125 °C.

The new MLX90641 is a small 16 x 12 pixel IR array housed in a 4-lead TO39 package that is able to accurately measure temperatures in the range -40 °C to +300 °C. The factory-calibrated devices ensure an accuracy of 1 °C in typical measurement conditions. The high accuracy is further supported by a Noise Equivalent Temperature Difference (NETD) of 0.1 K RMS.

Two different FoV options are available, a standard 55° x 35° and a wide angle 110° x 75°. The device is simple to use, operating from a single 3.3 V supply and storing all results in internal RAM for access via an I2C compatible digital interface. A proprietary algorithm ensures high thermal stability, even in conditions where the temperature is changing rapidly.
