Twin Element Detector LHi 1448
Four elements in two pairs
Two outputs, equal polarity
Designed for PIR alarms
Field of View
The LHi 1448 pyroelectric infrared detector is designed for high end PIR alarm
applications. It includes a twin type pyro-electric ceramic with 4 sensitive elements
connected to two FET source follower circuits.Thus it provides for dual channel
output . Both channels are of the same polarity.
The LHi 1448 detector is available inTO-5 housing with standard infrared filter. It
offers excellent common mode performance (match) and low noise.
