Pyroelectric detectors for motion Sensing
Product Description
This series of four element “Quad” detectors provides all four elements connected to one common
output. This configuration enables specific applications in ceiling mount location when applied with
suitable lens or mirror optics designs. Two different window options are provided: Large window or
standard rectangular window size. For better EMI protection, the built-in capacitor option is available.
