W12-3 Photoelectric Sensors

The IP 69K-rated W12-3 Photoelectric Sensors are ideal for withstanding harsh wash down environments. Using OES3 technology, SICK's third generation custom ASIC (application-specific integrated circuit), the W12-3 provides exceptional background and foreground suppression at an extended range.
The OES3 contains proprietary technology that enables the W12-3 to ignore stray background reflections, detect multi-colored/shiny objects, and provide high immunity to ambient light.
The W12-3 is the newest high-performance photoelectric sensor in the W12 family. Both non-programmable and programmable potentiometer versions of the W12-3 feature an IP 69K-rated metal housing (made of die cast zinc) that enables the sensor to stand up to harsh cleaning agents in food and beverage, packaging and pharmaceutical environments. In addition, the W12-3 offers multiple mounting options (dovetail base and back mount, flanged-base through hole, diagonal through holes), and a 270° rotatable connection.
