100% Original Thermopile IR Sensor -20ºC To 100ºC Working Temperature AAS-930-164B

AAS-930-164B Thermopile IR Sensor Applications

Features :

The thermopile has some unique properties not of-fered by other detectors:

• Response to broad infrared spectrum.
• No source of bias voltage or current needed.
• Inherently stable response to DC radiation.

Product Introduction :

A thermopile is a serially-interconnected array of thermocouples, each of which consists of two dissimilar materials with a

large thermoelectric power and opposite polarities. The thermocouples are placed across the hot and cold regions of a structure

and the hot junctions are thermally isolated from the cold junctions. The cold junctions are typically placed on the silicon substrate

to provide effective heat sink. In the hot regions, there is a black body for absorbing the infrared, which raises the temperature

according to the intensity of the incident infrared. These thermopiles employ two different thermoelectric materials which are

placed on a thin diaphragm having a low thermal conductance and capacitance.

Package :

Our thermopile detector is packaged with silicon filter and thermistor as shown below. We are supplying TO-5 package and

TO-46 package as the standard type , but on request, other package types are also available.
