Melexis MLX90632 Series Infrared Temperature Sensors

Award-winning Medical Grade Sensor in a compact SMD package

The Melexis MLX90632 infrared temperature sensor group is a miniature SMD thermometer IC for accurate non-contact temperature measurement, especially in thermally dynamic environments where space is limited.

The MLX90632 sensor thrives in applications such as server rooms, white goods, room temperature monitoring in smart thermostats, or integration into portable electronics devices.

Medical Grade MLX90632

A medical grade version of the Melexis MLX90632 is also available for body temperature measurements in applications such as health monitoring wearables and forehead/ear thermometers. The medical sensor is calibrated with an accuracy suitable for the narrow object temperature range of medical applications. The MLX90632 medical sensor applications include medical thermometers, smart glasses, and smart headphones.


As we become more conscious of our health and our environment, temperature sensing is now being added to many devices, including health monitoring devices in the form of medical body thermometers and smart wearable devices.
