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-E940ST1 realizes cost benefits and higher performance
with a new infrared sensor element of improved material
parameters and fabrication.
IRA-E940ST1 which has quad elements and 2 outputs will
detect the human body more correctly with OR/AND logic
circuit.
! Features
1. High sensitivity and excellent S/N ratio
2. High stability to the temperature change
3. High immunity to the external noise (Vibration, RFI etc.)
4. Higher in cost-performance
5. Custom design is available.
! Applications
1. Security
2. Lighting appliances
3. Household or other appliances
! Rating (25˚C)
