LHI778

Lighting | Imaging | Telecom Pyroelectric Infrared Detectors Dual Element Detector 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.
