The FX-40 passive infrared detector series is a high-precision, reliable passive infrared detector that uses a patented multi-focus optical spherical lens design to provide accurate detection performance and high durability. The detector also has a temperature compensation circuit that can improve detection performance in high-temperature conditions where the ambient temperature is close to human body temperature.
FX-40 Passive infrared detector series is a high precision and reliable passive infrared detector. It adopts a patented multi-focus optical spherical lens design, which has a very high vertical sector density. Even in high temperature or small environmental temperature difference, it can guarantee the detection sensitivity in the entire detection area.
