AFBR-S6PY2341中文资料Thin film analog pyroelectric single-channel IR sensor with 4.64 µm bandpass filter for flame detection数据手册Broadcom规格书

描述 Description

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-S6PY2341 is equipped with a 4.64 µm bandpass filter with typical cut on wavelengths at 4.55 µm and typical cut off wavelengths at 4.73 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.

简介

AFBR-S6PY2341属于传感器变送器的运动传感器-光学。由制造生产的AFBR-S6PY2341运动传感器 - 光学光学运动传感器系列产品使用光（通常是红外光）来检测物体的运动。无源红外型可检测落在传感器上的红外光量的变化，例如温暖的身体穿过传感器视场时引起的变化，而区域反射型可发射光，并检测附近物体反射的光量变化。此系列不包括能检测物体存在性而非运动的产品，例如用于机械安全的光幕。
