Lighting | Imaging | Telecom p Pyroelectric Infrared Detectors Four elements in two pairs Two outputs, equal polarity Designed for PIR alarms The LHi 1448 pyroelectric infrared detector is designed for high end PIR alarm applications. It includes a twin type pyro-electric ceramic with 4 sensitive elements connected to two FET source follower circuits.Thus it provides for dual channel output . Both channels are of the same polarity. The LHi 1448 detector is available in TO-5 housing with standard infrared filter. It offers excellent common mode performance (match) and low noise.
