Pyroelectric Infrared Detectors
Dual Element Detector
LHi 778
TO-5 housing
Competitive cost version
Designed for motion control
The LHi 778 pyroelectric infrared-detector series are the standard dual element
design recommended for all variants of motion control. They include a dual
element pyro-electric ceramic element with Fet in source follower connection.
LHi 778 detector is available in TO-5 housing with standard infrared filter. It
provides high responsivity with excellent common mode performance (match)
and low noise at steady state and temperature changes.
