The Zilog ZSLM323511 is a surface mount Passive Infrared (PIR) sensor designed for high-performance motion detection applications. It features dual sensing elements with a spectral filter tuned to 8-13um wavelength, offering excellent EMI immunity and protection against unwanted IR energy and white light. Its low-profile design is compatible with standard TO5 package dimensions, and it supports IR reflow processes. This sensor is ideal for security systems, lighting controls, video doorbells, and IP cameras.
