Infrared Photoelectric Sensor RGF-L1212

Summary:

The uncooled lead sulfide (PbS) sensor is a lead salt infrared photoelectric sensor. Its working principle is based on the photoconductive effect of semiconductor materials, thereby converting infrared radiation energy into electrical signals. The main response wavelength of PbS sensor is short-wave infrared (1.0~3.0μm), which is widely used in flame and high temperature detection.

Feature:

* TO-5 package; uncooled
* Fast response; high detection rate

APPLICATION

Infrared Alarm

The infrared alarm to prevent human intrusion is composed of pyroelectric infrared sensor and alarm controller. When someone enters the range to be protected, the sensor generates an electrical signal and transmits it to the controller, and the controller sends the alarm signal to the terminal through signal processing.
