Overview of Hex-shaped Fiber Units

The document introduces OMRON's new series of hex-shaped fiber optic sensor units, including models E32-LT11N, E32-LD11N, and E32-LR11NP. These units feature a compact hexagonal design with built-in lenses for enhanced detection stability and simplified installation.

Product Models and Types

• Through-beam Model: E32-LT11N
• Retro-reflective Model (for transparent object detection): E32-LR11NP
• Reflective Model: E32-LD11N
• Coaxial Reflective Model: E32-C21N
• Diffuse-reflective Model: E32-D21N
• Smart Fiber Amplifier Unit: E3NX-FA

Models are available with built-in lenses (15° aperture angle) or without lenses (60° aperture angle), providing options for different detection requirements.

Key Features and Benefits

• Built-in Lenses: Provide a narrow 15° aperture angle that reduces false detections caused by scattered light, enabling stable detection even in tight spaces and dusty environments.
• High Power Output: The E32-LT11N model offers approximately 10 times higher incident light levels compared to conventional units, improving detection reliability.
• Improved Signal-to-Noise Ratio (S/N): The E32-LD11N reflective model with built-in lens achieves about 3 times higher S/N ratio than conventional fiber units.
• Tool-friendly Hexagonal Design: Allows wrench tightening at only one nut without contacting or damaging the cable, simplifying installation and reducing damage risk.
• Easy Cable Routing: Wide cable opening facilitates straightforward cable management.
• Stable Detection in Dusty and Dirty Environments: High power and narrow field of view ensure long-term stable sensing.
• Lens Integration Advantages: Built-in lenses cannot fall off or be lost, eliminating the need for additional securing methods like tape or adhesives and reducing maintenance time.

Technical Specifications

• Sensing Distance: Up to 4,000 mm in GIGA-power mode with E3X-HD and E3NX-FA amplifiers.
• Response Times: Multiple modes including Super-high-speed (SHS), High-speed (HS), Standard (ST), and GIGA-power mode with response times ranging from 30 μs to 16 ms depending on the amplifier and mode.
• Minimum Sensing Object Size: As small as 0.03 mm diameter depending on model and amplifier.
• Mounting and Dimensions: Hexagonal nuts with M3, M4, or M6 threads; compact sizes with detailed dimensional drawings provided.
• Operating Temperature Range: -40 to 70°C.
• Cable Specifications: Polyethylene sheath with specified bending radius and tensile strength.

Installation and Accessories

• Installation: Simplified by hexagonal shape allowing single-nut tightening and preventing cable damage.
• Accessories: E39-F9W13 fiber attachment for space-saving cable management; E39-RP1 optional reflector for retro-reflective models.

Applications and Environmental Resistance

• Suitable for detecting transparent, low-reflective, or inconsistently oriented objects.
• Applicable in dusty, oily, or harsh industrial environments due to robust design and high power.
• Models equivalent to IP68g for oil resistance are available.

Summary of Advantages

• Stable and reliable detection with high power and narrow aperture.
• Reduced false detection from scattered light.
• Easy and reliable installation with tool-friendly hexagonal design.
• Maintenance reduction due to integrated lens design.
• Wide compatibility with OMRON fiber amplifier units (E3NX-FA, E3X-HD, E3X-DA-S).
