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.
