Thermopile detectors
T11262 series
High sensitivity,
for gas density measurement (T11262-01),
for flame detection (T11262-06)
The T11262-01 is a high-sensitivity thermopile detector suitable for gas density measurement or the like. It uses a TO-18
package with a window having high transmittance in the 3 to 5 μm spectral band. By attaching an external band-pass filter to
the thermopile detector, customers can apply it to various types of gas density measurements. The T11262-06 employs a 4.45
μm band-pass filter and is suitable for flame detection applications.

Precautions (T11262-06)
The T11262-06 band-pass filter has a second order transmission at 10 μm or higher. If this causes an unwanted effect, install a sapphire glass or the like in front of the light input window to cut the long wavelengths.
