Thermopile (single element type) T11262-01

Datasheet [206 KB/PDF]

The T11262-01 is a high sensitivity thermopile detector suitable for gas analysis applications. It uses a TO-18 package with a window having high transmittance in the 3 to 5 μm spectral band, the T11262-01 can be used for various type of gas analysis by externally attaching a band-pass filter on a user's end.
