| 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 with FET in source follower connection. The LHi 778 is available as TO-5 housing with standard infrared filter. It provides for high responsivity with excellent common mode performance (match). RF improved options are available. Best choice for human body detector. Highly sensitive to human body while remaining insensitive to ambient temperature change, vibration or optical noise. This is due to the dual configuration which electrically cancels such effects | |
