Hi,

Is there the reliability specifications of PAS CO2?
Especially, the customer wants to know " Vibration Test" and "Mechanical shock".

Best regards,

Hi @h_nakamura ,

The test conditions are as stated below : 

For mechanical shock : 
1500g / 0.5msec /
direction +/-x,y,z
(5 shocks in each direction)

For Vibration :
20 to 2000Hz with a peak acceleration of 20g in X, Y and Z for 4 minutes each

Hope this helps ! 

Best regards,

Deepa

Hi @h_nakamura ,

The system design guidelines have been stated according to the tests performed as listed in https://www.infineon.com/dgdl/Infineon-PAS_CO2_General_Design-In_Guideline.docx.-ApplicationNotes-v0... .In case of vibration, the only critical frequency would be low frequencies so if these can be isolated, the sensor will be very robust and in addition, it is IEC 60068-2-6 qualified. As for mechanical shock, the sensor is IEC 60068-2-27 qualified.

Best regards,

Hi,
Is it possible to know the test condition of IEC 60068-2-6 and IEC 60068-2-27 because I heard that the vibration is IEC 60068-2-6 qualified and the mechanical shock is IEC 60068-2-27 qualified.
