The Infrared Thermopile Sensor measures temperature without physical contact by detecting the infrared energy emitted by an object. As the temperature of the object increases, the amount of infrared energy it emits also increases.

The sensor's thermopile elements are composed of multiple miniature thermocouples integrated on a silicon chip. These thermocouples absorb infrared radiation and convert it into electrical signals.

The ISB-TS45D Infrared Thermopile Sensor is ideal for non-contact temperature measurement applications. It features components such as infrared filters and thermistors, all housed in a robust TO-46 metal package. This design ensures high sensitivity and reliability, making it suitable for a wide range of temperature sensing tasks.
