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. Features Applications Spectral response: 3 to 5 μm (T11262-01), 4.45 μm (T11262-06) Gas density measurement and the like (T11262-01) TO-18 package Flame detection (T11262-06) High sensitivity Absolute maximum ratings Parameter Operating temperature Storage temperature Symbol Topr Tstg T11262-01 -30 to +85 -40 to +100 T11262-06 -10 to +80 -20 to +85 Unit °C °C Structure Parameter Photosensitive area Package Window material Symbol A - Condition - T11262-01 T11262-06 1.2 × 1.2 TO-18 AR coating Si with 3 to 5 μm 4.45 μm band-pass filter high-transmittance Unit mm - Electrical and optical characteristics (Ta=25 °C) Parameter Symbol Spectral response Photosensitivity Element resistance Noise voltage Noise equivalent power Detectivity Rise time Temperature coefficient of element resistance Field of view λ S Re Vn NEP D* tr Condition 1 Hz, 500 K Johnson noise 0 to 63% TCR FOV Photosensitivity 50% T11262-01 Min.
