VT
Type P10-B68
Description： As an infrared temperature sensor,
thermopile can directly sense infrared thermal radiation,
convert heat into electrical signal,
the surface temperature of the object can be quickly measured without direct contact with the object to be measured.
The NTC thermistor packaged in the thermopile is used to measure the ambient temperature of the thermopile,
and use it as a temperature reference.
Features： 1.MEMS thermopile chip
2.TO-46 package
3.High sensitivity
4.(8~14um) bandpass filter
5.High precision NTC
◆Product application
-Non-contact temperature measurement
