LHI778 Infrared Thermoelectric Sensor For Human - body Movement Detectors

Product Features:

• It has a TO - 5 metal housing and different window sizes are available6. The LHI778 is designed to meet low - cost requirements and is equipped with a small - sized optical window.
• It is a dual - element detector, which includes a dual - element pyro - electric ceramic element with a FET in source - follower connection.
• It provides high responsivity, excellent common - mode performance (match), and has low noise in both steady - state and temperature - change conditions.
• It has improved EMI protection and reduced white - light immunity (WLI).
