Non Contact Thermometer Sensor offers Narrow Field Of View
Melexis introduced the MLX90614xAC with narrow 35° field of view (FOV). Design engineers can now measure smaller objects or increase the sensor-object distance with this thermometer. The 35 degree FOV is obtained by adding a viewing angle limiting metal tube to the standard TO-39 housing of the MLX90614. By performing the calibration of the thermometer after this tube has been attached, the accuracy of the temperature measurements can be maintained. The thermometer applies advanced low noise amplifiers, a 17-bit ADC, and powerful DSP unit in its signal conditioning chip allowing a wide operating -40°C to 125°C and an extended object temperature range of -70°C to 380°C while maintaining a temperature resolution of 0.02°C. The MLX90614xAC has an absolute accuracy of ±0.5°C in the object temperature range of 0°C to 50°C and ±1°C outside that range. The thermometer is qualified in accordance to AECQ100 and is ROHS compatible. It can be soldered up to 260°C according to JEDEC 020C be ordered with a lead time of 8 weeks.
