PYQ1398

Pyroelectric detectors for motion Sensing Pyroelectric Four-Element Detectors For Ceiling-Mount LHi 1128, PYQ 1398, PYQ 1348 – Single-Output “Quad” Pyro Applications Ceiling-Mount Alarms Ceiling-Mount Light Switches Features and Benefits TO-5 metal housing Different window sizes Single Channel output Product Description In this series of four-element “Quad” Detectors, all four elements are connected to one common output. This configuration enables specific applications in ceiling-mount locations, when applied with suitable lens or mirror optics designs. Two different window options are provided: a large window or standard, rectangular window size. Various element polarities are available upon request. For better EMI protection, the built-in capacitor option is available. For small Fresnel lens applications, a smaller element configuration is provided.
