Pyroelectric Detector by Excelitas Technologies

Note: Your Quotation Request will be directed to Excelitas Technologies.

The PYD 5731 from Excelitas Technologies is a Pyroelectric Detector that has a cut-on wavelength of 5.5 μm. It has a field of view of 99o and an optical distance of 500 μm. This pyroelectric detector has a responsivity of 11 kV/W and match of up to 10%. It has an average filter transmittance above 77% (for wavelength 7.5 μm - 13.5 μm) & below 0.5% (for wavelength less than 5 μm) and a noise of 70 μV. This pyroelectric detector has dual detectors with an element size of 1.4 mm x 0.4 mm and is RoHS compliant.

The PYD 5731 uses Sigma-Delta and DSP techniques for signal conversion and has a configurable motion detection unit. It requires a DC supply voltage of 3.3 V and consumes 10 μA of current. This pyroelectric detector is available in a TO-46 metal housing package that measures 17.06 (L) mm x 5.6 (W) mm x Ø 4.7 (H) mm and is ideal for mid-distance motion detection (with lens), energy saving, intrusion alarms, horizontal mounting, compact lens designs applications.
