Quad Element Detector LHi 1148
Field of View
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.
