Pyroelectric Infrared Detectors
Ceiling Application Detector LHi 1128
Four Element Detector
Single FET Output
Designed for Ceiling Mount Applications
The
LHi 1128
pyroelectric infrared detector is a special design for motion control
in ceiling mount applications. It includes a Quad type pyroelectric ceramic with
4 sensitive elements connected to one FET in source follower connection.Thus
it offers a single channel output .
The
LHi 1128
detector is available in
TO-5
housing with infrared filter. It offers
excellent common mode performance (match) and low noise.
