Pyroelectric Infrared Detectors
Dual Element Detectors
TO-39 housing
Wide field of view
Designed for motion control
RF Protection
The
LHi 944
pyroelectric infrared-detector series represents a special dual
element design recommended for motion control with extended Field of view.
They include a dual element pyroelectric ceramic with FET in source follower
connection, and RF protection by additional capacitor.
The
LHi 944
is available as
TO-39
housing with standard infrared filter. It offers
high responsivity with excellent common mode performance (match) and low
noise at steady state and temperature changes.
