OMRON E32-LT11N Hex Shaped Fiber Unit
NEW STANDARD FOR THE FUTURE
Introducing Hex-shaped Models with Build-in Lenses
Hex-shaped Fiber 
Unit Series
Fiber Units with Build-in Lenses
provide more stable detection and simpler, more reliable installation.
Hex-shaped models are now available with high-power built-in lenses for stable detection.
Achieve stable detection and easy onsite application.

Stable Detection
Long-term Stable Detection Even in Dusty Environments
The E32-LT11N’s incident light level is approx. 10 times higher than that of the conventional Fiber Units.*1 High power means stable detection even in dusty and dirty environments.
Stable Detection of Target Area Changes
The E32-LD11N’s signal change (S/N ratio) is approx. 3 times higher than that of the conventional Fiber Units.*2 Because the target area is viewed with the narrow field of a 15° aperture angle, there is a greater difference in incident light levels and objects can be detected reliably.
Reduce False Detection Caused by Scattered Light
False Detection is greatly reduced because the 15° aperture angle eliminates scattered light, even in tight spaces.
Build-in Lens Provides Simplicity and Reliability

- The following mode names and response times apply to the modes given in the Sensing distance column.
E3X-HD GIGA: Giga-power mode (16 ms), HS: High-speed mode (250 μs), ST: Standard mode (1 ms), and SHS: Super-high-speed mode (NPN output: 50 μs, PNP output: 55 μs)
E3NX-FA GIGA: Giga-power mode (16 ms), HS: High-speed mode (250 μs), ST: Standard mode (1 ms), and SHS: Super-high-speed mode (30 μs) - The optical fiber is 2 m long on each side, so the sensing distance is 4,000 mm.
- The values for the minimum sensing object are reference values that indicate values obtained in standard mode with the sensing distance and sensitivity set to the optimum values.
The first value is for the E3X-HD and the second value is for the E3NX-FA. - The sensing distances for Reflective Fiber Units are for white paper. The sensing distances for the E32-LD11N 2M are for glossy white paper.
Note. Objects with a high reflection factor may cause the Retro-reflective Fiber Sensor to detect reflected light as incident light.
Detection may be unstable depending on the type of transparent object. Check suitability beforehand.
