LHI1548

Lighting | Imaging | Telecom Pyroelectric Infrared Detectors Twin Element Detector LHi 1548 Four elements as two pairs Two outputs, inverse polarity Designed for PIR Alarm Systems The LHi 1548 pyroelectric infrared detector is designed for high end PIR alarm applications. It includes a twin type pyroelectric ceramic with 4 sensitive elements connected to two FET source follower circuits.Thus it provides for dual channel output . The channels are of inverse polarity. The LHi 1548 detector is available in TO-5 housing with standard infrared filter. It offers excellent common mode performance (match) and low noise Parameters min Element size R esponsivity Match Noise 4200 LHi 1548 p D A T A S H E E T typical 0,953 5000 1 30 ma x units mm2 V /W condition (4 elements) 100°C, 1 Hz 15 75 % µV pp 25°C , 0,3...10Hz Offset Voltage Right for modification reserved / WS /, 29.6.2001 0,2 1,55 8,6x10-10 28x10-10 V W Ö Hz RS =47kW , 25°C 1Hz Bw, 100°C, 1 Hz NEP D* Output Impedance Operating Voltage Field of View, horizontal vertical Operating Temp.
