The Omron E3C-LR11N 2M is a high-precision photoelectric sensor featuring a coaxial retro-reflective sensing method with MSR (Mirror Surface Rejection) functionality. Designed for long-distance detection up to 7 meters, it uses a Class 2 red semiconductor laser diode (650 nm, 3 mW max.) to achieve accurate and focused sensing, even on reflective or challenging surfaces. This sensor is ideal for applications requiring tight beam control and detection of small or distant objects in automated machinery and conveyors.
The sensor integrates a separate digital amplifier and is connected via a pre-wired 2-meter cable, offering flexibility for installation in space-constrained environments. It includes a green LDON indicator and orange operation indicator for quick status checks during operation. Operating from β10Β°C to 55Β°C, the E3C-LR11N 2M also supports storage conditions down to β25Β°C and up to 70Β°C without icing or condensation, making it reliable across a wide range of indoor automation setups.
Built for general industrial environments, it withstands ambient illumination up to 3,000 lx from incandescent lighting and tolerates humidity from 35% to 85% (operating and storage). The sensor offers solid electrical stability with 20 MΞ© insulation resistance at 500 VDC and a dielectric strength of 1,000 VAC at 50/60 Hz for 1 minute. Its vibration resistance (10β150 Hz at 0.7 mm double amplitude for 80 minutes) and shock resistance (300 m/sΒ² in 6 directions) allow it to perform consistently under mechanical stress.
Constructed with a durable ABS body and a glass front surface filter, the Omron E3C-LR11N 2M is compact and lightweight, yet stable in industrial conditions. While it carries an IP40 ratingβsuitable for protected indoor applicationsβit delivers excellent precision in environments where fine object positioning and reliable laser detection are essential. This model is commonly deployed in material handling, robotic arms, packaging lines, and automated inspection systems that demand reliable and repeatable laser-based sensing performance.
