Lighting | Imaging | Telecom p Pyroelectric Infrared Detectors Dual Element Detectors LHi 944 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.
