Pyroelectric detector
Quadrant pyroelectric detectors
P7108 series
P7108 series is a quadrant pyroelectric detector with a built-in FET, having four elements connected in series in a 2 2 format. This quadrant
element format allows detecting the minute motion of an object, independent of its movement direction. A desired field of view can be obtained by
selecting a lens that best matches your application.
Features
l Detects minute movements of the human body
l Independent of movement direction
l Various types of lenses available
(including custom-made lenses)
Applications
l Intruder alarms
l Automatic light switches
l Home electrical appliances
l Electronic toys
