D203S Pyroelectric infrared radial sensor The pyroelectric infrared sensor detects infrared radiation on the basis of the characteristics that the polarization of pyroelectric material changes with temperature. Dual compensated sensing elements are applied to suppress the interference resulting from temperature variation. As a result, the operating stability of the sensor is greatly improved Our products can be used in many applications. 1. Security systems 2. Burglar alarms 3. Visitor acknowledgement 4. Light switch control 5. Intellectualized toy Standards and specifications Recommended Model: D203S small window Encapsulation Type: TO-5 IR Receiving Electrode: 2,1mm, 2 elements Window Size: 4,3mm Spectral Response: 514m Transmittance: 75% Output Signal[Vp-p]: 3500mV Sensitivity: 3300V/W Detectivity (D*):1.4 ,108 cmHz1/2/W Noise[Vp-p]:
