ASIC-based Sensors Withstand Washdowns

W12-3 Photoelectric Sensors for harsh washdown environments use a third-generation custom ASIC (application-specific integrated circuit) that incorporates OES3 technology for background and foreground suppression at an extended range.

An OES3 chip contains proprietary technology that enables the sensors to ignore stray background reflections, detect multi-colored/shiny objects, and provide high immunity to ambient light. Both non-programmable and potentiometer versions of the sensor feature an IP 69K-rated, die-cast zinc metal housing to withstand harsh cleaning agents in food and beverage, packaging and pharmaceutical environments.
