Lighting | Imaging | Telecom p Pyroelectric Infrared Detectors Quad Element Detector LHi 1148 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.
