Pyroelectric infrared sensors, IRA series, exhibit high
sensitivity and reliable performance made possible by
Murata's ceramic technology and Hybrid IC technique
expertise developed over many years.
IRA-E700 series realizes cost benefits and higher
performance with a new infrared sensor element of
improved material parameters and fabrication.
IRA-E700 series is available in two types.
IRA-E710ST0 has enhanced immunity to RFI (Radio
Frequency Interference).
! Features
1. High sensitivity and excellent S/N ratio
2. High stability to the temperature change
3. Slight movement can be detectable.
4. High immunity to the external noise (Vibration, RFI etc.)
5. Custom design is available.
6. Higher in cost-performance
! Applications
1. Security
2. Lighting appliances
3. Household or other appliances
