Long-Range Retro-Reflective Photoelectric Sensor for Industrial Automation
The Omron E3FA-RP21 Photoelectric Sensor provides reliable, long-distance object detection up to 4 meters using retro-reflective sensing technology. Engineered for demanding industrial automation applications like high-speed bottle counting on production lines, this sensor features a compact M12 cylindrical body with IP67/IP69K protection for durability in harsh and washdown environments. Its polarized filter effectively eliminates false triggers from reflective surfaces, ensuring stable detection of glass, plastic, and metallic objects. With a fast response time and PNP output, the E3FA-RP21 integrates seamlessly into control systems for packaging, material handling, and assembly automation. The sensor operates on a 10-30VDC supply and offers selectable Light-ON/Dark-ON modes for maximum application flexibility across an operating temperature range of -40°C to 55°C.
