PHOTOELECTRIC SENSORS E3FA/E3RA/E3FB/E3RB M18 Plastic and Metal Housing Sensors Universal M18 cylindrical plastic or nickel-plated brass housing in straight or 90 angled models Rugged IP67, IP69K housing withstands high-pressure and high-temperature wash down High power red LED for easy sensor alignment and dependable outputs in dusty environments Compact and robust housing for easy integration into machines Retro-reflective models are polarized to prevent false reads on mirrored surfaces High EMC protection and ambient light immunity for detection stability in environments with excess noise or background light Unrivaled Detection with Simplicity in Setup and Installation The short body of the E3FA/E3RA fits in Visible red LED light for easy alignment. Transparent object detection sensors utilize tighter mounting spaces. Omrons unique technology for detecting objects with birefringent (double refraction) properties. Bright LED indicators for status visibility Flush mounting option for quick and High power LED to compensate for dirt and large sensor adjustors for use with a easy installation. and misalignment. standard size screwdriver. 1E3FA/E3RA/E3FB/E3RB Ordering Information E3FA/E3RA Plastic Housing Sensors Refer to Dimensions on page 14.
