Pyroelectric Infrared Detectors
Dual Element Detector LHi 968
High End Dual Element Detector
Special RFi Protection
Designed for PIR Alarms
The
LHi 968
pyroelectric infrared-detector series is specially designed for
Intrusion Alarm applications . It includes a dual element pyroelectric ceramic
with FET in source follower connection and RF protection by a resistor and
additional capacitor.
This detector is available in
TO-5
housing with an infrared filter which protects
the elements from strong white light disturbance. It offers high responsivity
with excellent common mode performance (match) and low noise.
