High-Flex Shielded Encoder Cable, 0.2 / 0.3 / 0.5 / 0.75 mm² Stranded Electrical Equipment Cable

High-Flex Shielded Encoder Cable: Precision Signal Integrity for Dynamic Industrial Automation

In the high-stakes world of industrial automation, a single millisecond of signal lag or one broken conductor can halt an entire production line. The 【High-Flex Shielded Encoder Cable】 is engineered specifically to be the reliable “nervous system” for multi-axis robots, CNC machinery, and high-speed servo systems. By combining superior electromagnetic interference (EMI) protection with extreme mechanical endurance, this cable ensures that your feedback loops remain crystal clear, even after millions of bending cycles.

Quick Summary for Industrial Engineers

The 【High-Flex Shielded Encoder Cable】 is a premium signal transmission solution featuring Class 6 ultra-fine stranded oxygen-free copper conductors and a dual-layer shield (Tinned Copper Braid + Aluminum Foil). Designed for drag chain environments, it supports over 10 million bending cycles and maintains stable performance in temperatures ranging from -40°C to +90°C. It is the ideal choice for minimizing downtime and increasing the Mean Time Between Failure (MTBF) in precision feedback systems.¹

Why Signal Integrity Depends on Your Encoder Cable Selection

Encoder signals are notoriously sensitive to the “noise” generated by nearby power cables and high-frequency motors. Without proper shielding and structural design, signal attenuation and ghosting become inevitable.

Eliminating EMI with Dual-Layer Shielding

As shown in our technical cross-sections (see Image 2 and 3), our cables utilize a high-density tinned copper braid with a coverage rate exceeding 85%, combined with an aluminum foil wrap. This “dual-shield” approach creates a Faraday cage that effectively blocks both low-frequency magnetic interference and high-frequency radio interference, ensuring that your encoder data arrives at the controller without corruption.¹

Managing the “Corkscrew Effect” in Motion

Standard industrial cables often fail when subjected to continuous torsion and linear motion, developing a permanent deformation known as the “corkscrew effect”.² Our 【High-Flex Shielded Encoder Cable】 employs a specialized core stranding technique and low-friction PTFE (Teflon) tape wrapping.² This allows the internal cores to slide freely against one another during movement, preventing internal stress buildup and conductor fatigue.²

Technical Specifications and Material Science

At Shanghai Rousheng, we believe that the foundation of a great cable lies in its materials. We offer a range of conductor sizes from 0.2 mm² to 0.75 mm² to fit various connector and power requirements.⁴

Jacket Durability: TPU vs. PVC

For environments involving heavy oil exposure, chemical splashing, or high-speed friction, we recommend our TPU (Thermoplastic Polyurethane) jacketed versions. TPU offers significantly higher abrasion resistance and low-temperature flexibility compared to standard PVC, making it the preferred choice for 6-axis robotic arms and outdoor automation.

Frequently Asked Questions (FAQ)

What is the minimum bending radius for this encoder cable?

For mobile installations in drag chains, we generally recommend a bending radius of $7.5 \times D$ to $10 \times D$ (where $D$ is the cable outer diameter). For fixed installations, this can be reduced to $5 \times D$.

Is this cable compatible with major encoder brands like Fanuc or Siemens?

Yes. Our 【High-Flex Shielded Encoder Cable】 is designed with the same electrical and mechanical parameters as manufacturer-standard cables (A-E/F-L/M-W), making it a high-performance, drop-in replacement for OEM tethers.

How does the cable handle high-speed movement?

Our cables are tested for travel speeds up to 180°/S in torsional applications and millions of cycles in linear drag chains. The use of ultra-fine copper strands ensures the cable remains supple and does not “work-harden” over time.

Can I get a customized core count or jacket color?

Absolutely. We specialize in special cable customization. Whether you need a specific number of twisted pairs (as seen in Image 2 and 5) or numbered core identification (as seen in Image 1), we can tailor the structure to your exact BOM.
