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.
