Quad Type Pyroelectric Infrared Sensor
IRA-E900
Series
Pyroelectric Infrared Sensors
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-E900 series realizes cost benefits and higher
performance with a new infrared sensor element of
improved material parameters and fabrication.
IRA-E900 series is available in two types.
IRA-E910ST1 has enhanced immunity to RFI (Radio
Frequency Interference).
▊ Features
1. High sensitivity and excellent S/N ratio
2. High stability to temperature changes
3. Slight movement can be detectable.
4. Non directional sensing with wide F.O.V.
5. High immunity to external noise (Vibration, RFI etc.)
6. Custom design is available.
7. Higher in cost-performance
▊ Applications
1. Security
2. Lighting appliances
3. Household or other appliances
▊ Rating (25˚C)
