7) Balance output : Max. 15 %
[|S1-S2| / |S1+S2|]<= 0.15
S1 : Signal output on Element A + C
S2 : Signal output on Element B + D
Balance output is measured at chopper frequency of 1 Hz when connected to the amplifier of gain 72.5 dB (at 1 Hz) and submitted to the emission of Infrared energy of 13 microW/cm2 from 420 K Black Body.
8) Frequency response : 0.3 Hz to 3.0 Hz / (+/-) 10 dB
Optical characteristics
1) Field of view : 132° from center of element on axis X,Y
: 146° from center of element on 45°
2) Filter substrate : Silicon
3) Cut on (5 %T ABS) : 5.5 (+/-) 0.5 micron
4) Transmission : >=70 % average 7 to 14 micron
Environmental requirements
1) Operating temperature : -30 degC to +70 degC
2) Storage temperature : -40 degC to +80 degC
3) Relative humidity : The sensor shall operate without increase in noise output when exposed to 90 ~ 95 % RH at 30 degC continuously.
4) Hermetic seal : The sensor shall be sealed to withstand a vacuum of 21.28 kPa.
RoHS compliance

Working Principle 

Pyroelectric infrared sensor would change charge when radiant energy changes. The effect can be used in detecting the change of infrared radiant.The sensors apply to human motion detector,passive infrared burglar alarm and automatic light switch. Based on the same theory, the pyroelectric infrared sensor applies to gas detection with infrared absorption.

Typical  Application 
1. Passive infrared burglar alarm: strong anti-interference for strong with light and electromagnetic radiation
2. Human motion detector 
3. Human motion detector of ceiling 
4. Gas analysis
5. Non-contact infrared measurement 

Our Service
1.OEM and ODM are welcome.
2.Small quantity order is welcome.
3.Sample lead time: 1-3 days
4. Your inquiry for our products will be replied in 10 hours.
