The PYD 2592 from Excelitas Technologies is a Pyroelectric Detector that has a cut-off wavelength of 5.5 μm. It has a field of view of 146o and an optical distance of 550 μm. This pyroelectric detector has a responsivity of 3.7 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 30 μV. This pyroelectric detector has dual detectors with an element size of 2 mm x 1 mm and is RoHS compliant.
The PYD 2592 uses Sigma-Delta and DSP techniques for signal conversion and has a configurable motion detection unit. It requires a DC supply voltage of 3 V and consumes 3 μA of current. This pyroelectric detector is available in an LCC surface-mount package that measures 7 (L) mm x 5 (W) mm x 2.85 (H) mm and is ideal for long-distance motion detection (with lens), energy saving, intrusion alarms, horizontal mounting, battery operation, touchless switch & gesture direction recognition applications.
