LHi 944
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.
