AB 80026-053-07-R Fiber Optic Duplex Cable

Allen-Bradley / Rockwell Automation 80026-053-07-R Fiber Optic Duplex Cable Overview

The Allen-Bradley / Rockwell Automation 80026-053-07-R is a specific model of fiber optic duplex cable. As part of Rockwell Automation's extensive range of industrial connectivity solutions, this cable is designed for reliable and high-speed data transmission in industrial automation environments. Its fiber optic nature makes it immune to electromagnetic interference (EMI), which is crucial in noisy industrial settings. The "7.0M" indicates its length, and "VDF" suggests its application with Variable Frequency Drives, while "ROTOPALA FAM" hints at its use with a family of rotary position or motion sensing devices.

Product Detailed Description

• Function:

• Transmits digital data signals over fiber optic strands.

• Converts electrical signals into optical signals at one end and back into electrical signals at the other, enabling communication between industrial devices.

• Provides high-speed and reliable data communication, essential for modern automation systems.

• Immune to electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring data integrity in electrically noisy environments.

• Eliminates ground loop issues often associated with copper cabling over long distances.

• Features:

• Duplex Cable: Contains two fiber optic strands (one for transmit, one for receive) within a single jacket, allowing for full-duplex communication.

• Fiber Optic Technology: Utilizes light pulses for data transmission, offering superior noise immunity and longer transmission distances compared to copper cables.

• Length: Specifically 7.0 meters. This fixed length suggests it's a pre-assembled, ready-to-use cable.

• Industrial Grade: Designed for robustness and durability in harsh industrial environments, capable of withstanding vibration, temperature fluctuations, and exposure to certain chemicals.

• Application Focus (VDF/ROTOPALA FAM): The "VDF" (likely Variable Frequency Drive) designation implies it's suitable for connecting VFDs to controllers or other VFDs, often for high-speed communication of motor control signals or feedback. The "ROTOPALA FAM" suggests its use with rotary encoders or similar devices that require high-integrity, noise-immune feedback.

• Connectors: While not explicitly stated in the search results, it would typically come pre-terminated with standard fiber optic connectors (e.g., ST, SC, LC, or custom industrial connectors) compatible with Allen-Bradley / Rockwell Automation hardware.

Product Parameters

(Note: Specific optical parameters would depend on the fiber type, which is not explicitly stated. This cable would typically use multi-mode fiber for these lengths.)

• Cable Type: Fiber Optic Duplex Cable

• Manufacturer: Rockwell Automation / Allen-Bradley

• Part Number: 80026-053-07-R

• Length: 7.0 meters (7,0M)

• Application (Implied): VDF (Variable Frequency Drive) connectivity, ROTOPALA FAM (Rotary encoder/motion control family).

• Fiber Type (Typical for industrial short runs): Multi-mode fiber (e.g., 62.5/125 µm or 50/125 µm), suitable for industrial Ethernet or serial communication.

• Jacket Material: Industrial-grade, possibly PVC, LSZH (Low Smoke Zero Halogen), or PUR for flexibility and durability.

• Operating Temperature: Typically wide range, suited for industrial environments (e.g., -20°C to +70°C).

• Minimum Bend Radius: Specified in datasheets for proper installation.

• Insertion Loss: Specified in datasheets, indicating signal degradation over distance.

• Return Loss: Specified in datasheets, indicating signal reflections.

Product Advantages

• EMI/RFI Immunity: Unaffected by electromagnetic and radio frequency interference, critical for reliable data transmission in electrically noisy industrial plants.

• High Bandwidth & Speed: Capable of transmitting data at high speeds over relatively long distances without significant signal degradation.

• Electrical Isolation: Provides complete electrical isolation between connected devices, eliminating ground loops and preventing transient voltage damage.

• Enhanced Safety: No electrical current in the fiber optic cable, reducing the risk of sparks or electrical shock in certain environments.

• Reliability: Designed for industrial robustness, ensuring long-term stable operation in demanding conditions.

• Simplified Troubleshooting: Duplex nature makes transmit/receive path identification straightforward.

• Pre-assembled & Tested: As a specific part number, it's likely pre-terminated and factory-tested, reducing installation time and potential wiring errors.

Precautions

• Minimum Bend Radius: Do not bend the fiber optic cable below its specified minimum bend radius to prevent fiber damage and signal loss.

• Dust and Contamination: Keep fiber optic connector ends clean. Dust and contaminants can severely degrade signal quality. Use proper cleaning kits.

• Connector Compatibility: Ensure the cable's connectors are compatible with the ports on the Allen-Bradley / Rockwell Automation devices (VFDs, controllers, etc.) you intend to connect.

• Installation: Handle fiber optic cables with care. Avoid pulling, twisting, or crushing them during installation. Use appropriate cable management.

• Eye Safety: Never look directly into an active fiber optic cable. Although the light power is generally low for industrial communication, it can still cause eye damage.

• Strain Relief: Properly secure the cable and provide adequate strain relief at connection points to prevent damage from tension or vibration.

• Fiber Type Matching: Ensure the cable's fiber type (e.g., multi-mode 62.5/125 µm) matches the requirements of the transceivers in the connected devices.

Product Applications

This fiber optic duplex cable is specifically designed for applications within industrial automation, particularly those involving Allen-Bradley / Rockwell Automation systems:

• Variable Frequency Drives (VFDs): Connecting VFDs to PLCs/controllers for high-speed command signals (e.g., speed reference) and feedback (e.g., actual speed, current, fault status), especially in environments prone to electrical noise.

• Motion Control Systems: Interconnecting rotary encoders or other motion feedback devices (as hinted by "ROTOPALA FAM") with servo drives or motion controllers where precise, noise-immune feedback is critical.

• Distributed I/O Systems: Extending communication networks for remote I/O modules in areas with high EMI.

• Process Control: Ensuring reliable data transfer in sensitive process control applications where electrical interference could compromise system integrity.

• Long-Distance Industrial Networks: While 7 meters is relatively short, fiber optic cables are also used for longer runs within factories where copper cables would experience unacceptable signal degradation or be susceptible to interference.
