Product Description

D204s pyroelectric infrared radial sensor with cheap price all-purpose dual element pyroelectric infrared radial sensor d204s 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.light switch control 4 intellectualized toy 5.visitor acknowledgement standards and specifications recommended model:d204s small window encapsulation type:to-5 ir receiving electrode:2×1mm, 2 elements window size:3*4mm wavelength:5—14µm transmittance:=75% output signal[vp-p]:=3500mv sensitivity:=3300v/w detectivity (d*):=1.4 ×108 cmhz1/2/w noise[vp-p]:<70mv output balance:<10% offset voltage:0.3~1.2v supply voltage:3—15v operating temp:-30—70ºc storage temp:-40—80ºc feature 1. high sensitivity 2. long detecting distance 3. wide angle 4. strong stability 5. wide application fields 6. 2 years warranty 7. anti-electromagnetic interference optional information - payment : tt, western union - delivery : 3 working days - origin : china - minimum order : 1000pcs - packaging : 100pcs/small box
