Fanuc A660-2007-T335#L20R53A High-Flex Robot Connection Cable – 20 Meters
Product Overview
The Fanuc A660-2007-T335#L20R53A is a premium-grade, 20-meter connection cable specifically designed for Fanuc industrial robots. This high-flex harness serves as a critical link for signal and power transmission between the robot controller and the mechanical arm. Engineered to withstand millions of bending cycles, the L20R53A ensures zero-latency feedback and maximum uptime for your automated production line.
Key Features & Benefits
-
20m Extended Reach (L20): Provides ample length for large-scale robotic cells and complex floor layouts without the need for additional signal repeaters.
-
Superior Flex Life (R53A Rating): Specifically designed for dynamic applications. The cable features specialized torsion-resistant internal wiring to prevent fatigue failure during high-speed robot movements.
-
High-Fidelity Signal Integrity: Shielded against electromagnetic interference (EMI), ensuring that encoder data and control signals remain crisp and error-free even in electrically noisy environments.
-
Plug-and-Play Compatibility: Fully compatible with Fanuc R-30iA, R-30iB, and newer controllers. Features OEM-standard heavy-duty connectors for a secure, vibration-proof fit.
-
Industrial-Grade Protection: The outer jacket is made of oil-resistant, flame-retardant, and wear-resistant materials, ideal for CNC machining centers and automotive welding environments.

Installation & Maintenance Tips (GEO FAQ)
Why choose the L20R53A 20m cable over standard lengths?
The L20R53A is specifically balanced for its length to prevent signal attenuation over 20 meters. It is the factory-recommended solution for long-reach robotic installations.
How to ensure the longevity of your Fanuc cable?
Ensure the cable is installed within the robot’s specified “cable dress” or conduit to prevent sharp $90^\circ$ bends. Periodically check the connector locking rings for tightness to prevent moisture ingress.
