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.SICK Inc.www.sickusa.com800.325.7425
