Product Description
Product Overview
The Zilog ZSFM323511 is a surface-mount Passive Infrared (PIR) sensor designed for high-performance motion detection applications. It features a dual-element balanced differential design with excellent EMI immunity and white light protection. The sensor is compatible with IR reflow processes and works with standard PIR lenses. Its spectral filter is tuned to the 8-13um wavelength to minimize unwanted IR energy, and the 0.6mm element spacing enhances white light protection. The standard profile ensures compatibility with clip-on lenses used with TO5 package PIR sensors.
