PART/ PYD 1378 (LHi 778)
Analog Low-Cost Dual-Element Detector PYD 1378
The Excelitas Analog Low-Cost Dual-Element Detector PYD 1378 (replacement to the LHi 778) features two elements in series connection with FET in-source follower circuit, integrated into a TO-5 metal housing with a small optical window.
This Pyrodetector provides two sensing elements in opposed series connection and a source follower circuit. The PYD 1378 delivers exceptional economy and value for high-volume motion detection applications without sacrificing performance.
