The Omron E3S-CT11 2M is a high-performance, oil-resistant photoelectric sensor designed for long-range detection in industrial environments. Utilizing a through-beam configuration (emitter + receiver), it offers a maximum sensing distance of 30 meters, making it ideal for detecting large objects or targets across wide production lines. The sensor uses an 850 nm infrared LED to ensure stable performance, even under varying ambient lighting conditions.
This model operates on a 10 to 30 VDC power supply (with 10% ripple) and features an open collector output that is NPN/PNP selectable, allowing seamless integration into both legacy and modern control systems. It supports a maximum load current of 100 mA at 30 VDC, with residual voltage of 1.2 V max for NPN and 2.0 V max for PNP configurations. A one-turn adjuster provides convenient sensitivity control, while Light-ON/Dark-ON modes are selectable based on application needs.
Built for reliability, the E3S-CT11 2M offers a fast 1 ms max. response time, enabling use in high-speed automation tasks. Status indicators improve setup and diagnostics, while built-in protections safeguard against reverse polarity and output short circuits. Its environmental durability is further enhanced by its strong electrical insulation (20 Mฮฉ at 500 VDC) and dielectric strength (1,000 VAC for 1 min).
This sensor is rated IP67 under IEC 60529 and NEMA 6P (indoors), with oil resistance verified by in-house standardsโmaking it suitable for environments with lubricants, cutting fluids, or washdown requirements. It withstands vibration from 10 to 2,000 Hz and shock up to 1,000 m/sยฒ across all axes, maintaining consistent performance under mechanical stress. It operates from โ25ยฐC to 55ยฐC and stores between โ40ยฐC to 70ยฐC, tolerating humidity up to 95% without condensation.
The Omron E3S-CT11 2M is ideal for automotive, metalworking, and heavy machinery applications that demand long-range detection and rugged environmental resistance. Its oil-resistant build, fast response, and flexible output configuration make it a powerful sensing solution for challenging industrial use cases.
