MISMI 2517 8-Core 0.5mm² Servo Cable

Signal drift and unplanned downtime in multi-axis CNC systems don’t come cheap. A single intermittent connection can scrap a batch of precision components or stall a packaging line for hours. The MISMI 2517 8-core servo cable isn’t a miracle fix. It’s a supply chain decision that removes one variable from your reliability equation — delivering consistent 0.5mm² conductor geometry and shielded signal integrity where motor feedback loops can’t tolerate guesswork.

Engineered specifically for medium-duty servo drives operating in flexing cable tracks, this cable addresses the two procurement headaches we see repeatedly: premature jacket fatigue and cross-talk between adjacent signal pairs. By standardising on this specification, maintenance teams cut cable-related motor faults by a measurable margin. Field replacements drop. Spare parts inventory simplifies. Those numbers show up directly in your OEE metrics.

Why This Cable Builds Better Uptime

Tinned Copper Stranding, 0.5mm² × 8 Cores
Each conductor uses finely stranded, tinned copper wire. The tinning layer prevents oxidation at termination points. In high-humidity enclosures or unheated factory spaces, bare copper develops a resistive oxide crust within months. That crust generates heat. Heat accelerates insulation degradation. By specifying tinned copper from the start, you eliminate a slow-burn failure mode that rarely triggers alarms until the connection fails outright. Your termination torque stays consistent. Panel maintenance intervals extend.

Double-Layer Shielding: Aluminium Foil + Tinned Copper Braid
The foil wrap handles high-frequency noise. The braid absorbs low-frequency interference. Together, they create a Faraday cage around the signal cores without adding excessive stiffness. What this means for your encoder or resolver feedback: step-and-direction pulses arrive at the drive clean. No false counting. No position correction errors. For procurement teams evaluating cable specs, the practical metric is shielding coverage. This braid delivers ≥85% optical coverage. Sufficient for installations running VFDs in adjacent cable trays.

PUR (Polyurethane) Outer Jacket
PVC jackets crack in continuous-flex applications. That’s not opinion — it’s polymer chemistry. PUR resists abrasion, mineral oils, and the repetitive bending stress common in cable chains on gantry robots and pick-and-place units. Field data from automated warehouses shows PUR-sheathed cables outlasting PVC equivalents by 2 to 3 times in high-cycle routes. Lower replacement frequency. Fewer midnight call-outs. Your MRO budget stabilises.

Colour-Coded Cores with Numbered Printing
Eight cores. Black jacket. When a technician troubleshoots a fault at 3 AM under emergency lighting, they don’t want to trace wires by elimination. Each core carries a durable printed number and distinct insulation colour. Termination errors drop because the wiring schedule is unambiguous. Panel build time shrinks. Commissioning checks proceed without rework loops caused by crossed signal pairs.

Cold Flexibility Down to -25°C
Standard PVC cables stiffen below freezing. PUR compounds retain flexibility without cracking. For cold storage logistics, outdoor gantry systems in northern climates, or unheated production halls, this characteristic eliminates brittle fractures during winter startups. The cable moves with the machine, not against it.

Technical Specifications

Where This Cable Deploys

• CNC Machining Centres — Connects servo drives to spindle and axis motors where coolant mist and metal chips demand oil-resistant jacketing. The double shielding prevents encoder signal corruption from adjacent spindle drive cables.
• Automated Packaging Lines — Installed in cable tracks on high-speed cartoners and palletisers. PUR jacket withstands the constant back-and-forth flexing without developing stress cracks that expose conductors.
• Robotic Pick-and-Place Cells — Feeds servo motors on delta robots and SCARA arms. Torsional stress accumulates on every cycle. Tinned copper stranding handles this better than rigid solid-core alternatives.
• Cold Storage Logistics — Conveyor servo cabling operating at -20°C or below. Standard jacket materials embrittle. This cable maintains flex performance without needing heated trunking.
• Textile Machinery — Environments saturated with airborne fibre dust and lubricant mist. The smooth PUR jacket resists particulate adhesion and wipes clean, preventing layer build-up that traps heat.

Compliance & Quality Assurance

• ✅ IEC 60332-1-2 — Flame propagation test passed. Approved for installation in machinery where fire containment matters.
• ✅ EN 50363-10-2 — PUR sheath compound certified for oil resistance. Validated against common industrial lubricant and coolant exposure.
• ✅ CE Marking — Conforms to EU Low Voltage Directive 2014/35/EU.
• ✅ RoHS Compliant — All materials verified below restricted substance thresholds.
• ✅ ISO 9001:2015 — Manufactured under a quality management system with full batch traceability from raw copper sourcing to final test.
• ✅ 2000V Routine Test — Every production metre undergoes core-to-core high-voltage testing before shipping. No batch sampling. No exceptions.

Frequently Asked Questions

Can you supply this cable with a different number of cores or conductor sizes?
Yes. The 2517 series is one variant in a broader servo cable range. We manufacture 4-core, 8-core, and 12-core configurations with conductor areas from 0.14mm² to 2.5mm². Minimum order quantities apply for non-stock combinations. Typical lead time for custom core counts runs 4–6 weeks depending on raw material availability at our extrusion line.

What bending radius do I need to maintain in a cable chain installation?
For flexing applications, keep the bend radius no tighter than 7.5 times the cable’s outer diameter. For this 8.5mm OD cable, that means a minimum radius of approximately 64mm. Exceeding that radius accelerates jacket fatigue. If your cable chain has tighter turns, specify a smaller-diameter cable or redesign the routing. The 4× OD rating applies only to fixed installations.

How do you test shielding effectiveness before shipment?
Every reel undergoes a spark test and a continuity check on the shield braid. We measure resistance end-to-end across the braid to verify consistent coverage. For customers with stringent EMC requirements, we can provide test reports showing transfer impedance values across a 1–30 MHz frequency range. Request this documentation with your RFQ if your application involves drives switching above 4 kHz.

What’s the standard put-up length, and do you offer pre-cut lengths?
Standard reels ship in 100-metre and 500-metre lengths. Pre-cut, terminated lengths are available through our value-added service. Provide your connector specifications and cable schedule. We integrate assembly and testing before dispatch. Lead time extends by 3–5 working days for terminated orders.

Start with a Test Reel

A 100-metre reel lets you run accelerated flex testing on your own equipment and verify termination compatibility with your existing connectors. No commitment beyond that. If the cable performs, we can build a quarterly delivery schedule with fixed pricing for 12 months to insulate your project budget from copper price volatility.
