AFBR-S6PY0573 - Thin film analog pyroelectric single-channel IR sensor with 4.35 µm bandpass filter for flame detection

Product Detail

Broadcom's thin film pyroelectric infrared flame detectors offer exceptionally high responsivity, a wide field of view of typically 100° (*subject to filter band pass specification) and class leading rapid recovery from thermal and electrical shocks (<1 second downtime). The analog single detector AFBR-S6PY0573 is equipped with a 4.35 µm bandpass filter with typical cut on wavelengths at 4.05 µm and typical cut off wavelengths at 4.65 µm. This current mode sensor has excellent signal-to-noise at the signature 8-10 Hz flicker range of a flame, and can provide accurate discrimination of flame sources in triple IR flame detection systems. The sensor element is built into a low noise circuit that has an internal CMOS op amp with a 10GΩ feedback resistor outputting a voltage signal centered on half the supply rail.
