Quad Type Pyroelectric Infrared Sensor

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)
