Overview

Zilog’s Passive Infrared (PIR) sensors are designed to deliver high performance and

excellent EMI immunity for the most demanding motion detection applications.

The ZSFM323511 PIR sensor is a surface mount device compatible with IR reflow

processes. It is used in combination with a PIR lens and consists of two sensing elements

behind a spectral filter window tuned to 8-13um wavelength to help block out unwanted IR

energy sources. The 0.6mm element spacing provides additional white light protection.

The ZSFM323511 has a standard profile making it compatible with clip-on lenses used with

standard TO5 package PIR sensors.
