20-Core 0.2mm² Shielded Servo Cable, Oil-Resistant
Signal drift, unplanned downtime, and cable replacement in harsh environments destroy profit margins on automated lines. This 20-core 0.2mm² shielded servo cable is built for motion control systems where oil, flexing, and electrical noise converge. It keeps signal paths clean and your machines running. Fewer cable swaps. Longer maintenance intervals.
Shielding Architecture That Blocks Crosstalk
High-density tinned copper braid, 85% minimum coverage.
Standard foil wraps degrade after repeated flex cycles. A braided shield maintains its low-resistance path to ground across millions of cycles. Differential signal pairs inside the cable stay phase-aligned, even when routed alongside VFD motor cables. Your servo drives read encoder feedback correctly on the first pass—no retries, no position errors, no scrapped parts.
Oil-Resistant Jacket Formulated for Wet Environments
PVC/nitrile compound, tested in ISO 1817 immersion.
Cutting fluids, hydraulic oil, and way lube attack generic cable jackets within months. This jacket compound resists swelling, cracking, and embrittlement after prolonged oil contact. It holds up inside cable carriers on CNC lathes, injection molding machines, and metal stamping presses. Replace cables based on wear cycles, not chemical degradation.
20-Core Configuration Reduces Wiring Complexity
20 conductors, 0.2mm² cross-section per core.
Combining multiple signal circuits into a single cable eliminates bundling errors and shrinks cable carrier volume. Color-coded cores speed up termination. Field engineers spend less time tracing conductors. For multi-axis machines, a single pull handles all encoder, brake, and thermal sensor wiring. Less tray weight. Cleaner panel entries.
Stranded Copper for Continuous Flex Applications
Class 6 extra-fine stranded conductors.
Solid or coarse-stranded conductors work-harden and snap inside drag chains. Fine stranding distributes bending stress across more individual wires. The result: a bend radius down to 7.5x outer diameter, tested to 5 million flex cycles minimum. Cable carriers run longer between scheduled replacements. Unplanned line stops drop.

Industry Applications
- CNC Machining Centers. Continuous flexing inside cable carriers while submerged in cutting fluid mist. The oil-resistant jacket prevents jacket degradation that shorts signal cores mid-cycle.
- Plastic Injection Molding. Routing encoder and brake wiring to servo motors positioned above hot mold platens. Braided shielding rejects EMI from nearby induction heating circuits.
- Automated Packaging Lines. High-speed reciprocating motion on flying shears and form-fill-seal jaws. Fine stranded conductors endure the constant acceleration-deceleration without fatigue failure.
- Robotic Welding Cells. Spatter-resistant installation on articulated robot arms. The 20-core bundle consolidates feedback wiring, reducing the number of cables snaking through the robot wrist.
- Textile Machinery. Humid, lint-heavy environments where signal quality degrades. Tinned copper braid continues to block noise even as surface oxidation develops over thousands of hours.

FAQ
Q: What’s the maximum cable length before signal degradation becomes a concern at 0.2mm² cross-section?
The answer depends on your drive’s encoder interface voltage and frequency. For 5V differential signals (RS-422), we recommend staying under 25 meters total loop length at 1 MHz clock rates. At 12V or 24V signal levels, reliable operation extends beyond 50 meters. The dominant factor is voltage drop across the conductor resistance, not the shielding performance. We can provide S-parameter test data for specific lengths if your application pushes these boundaries.
Q: Does the oil-resistant jacket hold up against synthetic esters and bio-based hydraulic fluids?
Yes, with a note: The PVC/nitrile compound was immersion-tested against mineral oil (IRM 902) per ISO 1817. Synthetic esters and bio-based fluids are more aggressive plasticizers. We recommend requesting a material compatibility test coupon if your facility runs these fluids. Test it on a 200mm jacket sample submerged at your operating temperature for 72 hours. You’ll have your answer.
Q: We’re replacing a 20-wire unshielded bundle. Can this cable handle the same bend radius in our existing carrier?
The 7.5× OD bend radius spec is based on continuous flex cycling to failure at 5M+ cycles. Your current unshielded bundle likely operates near 10× OD. A 9.5mm OD on this shielded cable gives you a 71mm dynamic bend radius. Measure your carrier’s bend radius first. If it’s tighter than 71mm, we stock 18-core and 14-core variants with smaller OD options that might drop into your existing carrier without a redesign.
