BROADCOM AFBR-S6PY0573 Pyroelectric IR Flame Sensor, 4.35µm, Analogue, 1 CH, TO-39

AFBR-S6PY0573 is a thin film analogue pyroelectric single-channel IR sensor with 4.35?m bandpass filter for flame detection. This current mode sensor has excellent signal-to-noise at the signature 8-10Hz flicker range of a flame, and can provide accurate discrimination of flame sources in triple IR flame detection systems. This analogue single detector is equipped with a 4.35µm bandpass filter with a typical cut on wavelength at 4.05µm and a typical cut-off wavelength at 4.65µm. The sensor element is built into a low-noise circuit that has an internal CMOS op amp with a 10Gohm feedback resistor outputting a voltage signal centered on half the supply rail. Applications include NDIR gas detection, flame detection, NDIR pellistor and electrochemical replacements, automotive gas analysis, medical gas analysis, anaesthesia, fluid analysis, food safety, THz detection, energy measurement, miniaturized designs.
