Model 407 Thermally Compensated Pyroelectric IR Detector
●One centrally located sensing element is exposed to infrared radiation entering through the opti-cal filter while the second element is shielded from outside radiation.
●The sensing elements are con-nected electrically in a parallel op-posed configuration for cancel-lation of signals generated by both crystals due to thermal changes in the housing environment.
●A source resistor is required to set the drain current and the operating parameters of the JFET. A value of 47k Ω or greater is recommended.
