Twin Element Detector LHi 1548
Field of view
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
