| Lighting | Imaging | Telecom Pyroelectric Infrared Detectors Quad Element Detector LHi 1148 Four elements in two pairs Two FET outputs, inverse polarity Designed for redundant PIR alarms The LHi 1148 pyroelectric infrared detector is designed for high end PIR alarm applications. It includes a Quad type pyroelectric ceramic with 4 sensitive elements connected to two FET source follower circuits. Thus it provides for dual channel output . One channel is inverse to the other. The LHi 1148 detector is available in TO-5 housing with standard infrared filter. It offers excellent common mode performance (match) and low noise. p DATASHEET Parameters min Element size R esponsivity Match Noise 3 500 LHi 1148 typical 1,375x1 4 500 1 30 ma x units mm2 V /W condition (4 elements) 100C, 1 Hz 10 75 % V pp 25C , 0,3...10Hz Offset Voltage Right for modification reserved / WS /, 29.6.2001 0,2 8,6x10-10 5x10 7 1,55 28x10-10 V W O Hz RS =47kW , 25C 1Hz Bw, 100C, 1 Hz NEP D* Output Impedance Operating Voltage 2 14x10 5 7 cm O Hz/W 1Hz Bw, 100C, 1 Hz 10 15 kW V RS =47kW , 25C RS =47kW , 25C unobstructed unobstructed 85 85 C C non permanent non permanent Field of View, horizontal vertical Operating Temp.
