Hamamatsu New High Sensitivity Single Element Thermopile Sensor for Infrared Detection

Thermopile sensors are created by connecting a number of thermocouples in series, where a thermocouple is a junction between two different metals that produces a voltage related to a temperature gradient across the junction.

The T11262-01 output is proportional to incident radiation (DC coupled) and the detector features very low impedance compared to a pyroelectric sensor. This allows for simplified associated circuitry for the thermopile and less affects from extraneous radiation and electrical noise.

With the addition of a bandpass filter the T11262-01 is an ideal sensor for use in a wide range of gas analysis applications as well as in process control and security applications.
