INTRODUCTION
Industrial servo systems demand cables that survive relentless motion. Every second, a CNC gantry cycles its Y-axis cable through a tight-radius drag chain. Every shift, a robot arm twists its servo wiring through 3D trajectories. Every hour, a packaging machine flexes encoder feedback lines in high-frequency reciprocating motion. When a cable fails, the line stops — and downtime costs more than any cable ever will.
Derul Cable's DERUL-SV Servo Motor Cable Series is purpose-built for these environments. Using Class 6 ultra-fine stranded tinned copper, low-capacitance insulation, and wear-resistant PUR jacketing, each cable is designed to outlast the machine it powers.
Derul supplies the raw cable in bulk reels or cut lengths. You handle connector termination. The cable is electrically compatible with drives from:
Mitsubishi (MR-J3/J4/J5 series)
Delta (ASDA-A2/B2/A3/B3)
Yaskawa (Sigma-5/7 series)
Inovance (SV660/630 series)
Siemens (Sinamics V90/S120)
Panasonic (Minas A5/A6)
Fanuc, ESTUN, Leadshine, and other standard AC servo drives
Note: We supply cable only. For pre-terminated cable assemblies with molded connectors, please contact us with your connector part numbers.
ADVANTAGES
Engineered for continuous flexing inside cable drag chains, gantry robots, and CNC machine tool axes. The Class 6 ultra-fine stranded tinned copper conductors combined with a low-friction PUR jacket deliver ≥5 million bending cycles at 7.5× OD bend radius. Unlike standard PVC servo cables that crack and short after months in a drag chain, Derul's DERUL-SV series is built for 24/7 automated production lines.
Electromagnetic noise from VFD drives, spindle motors, and adjacent power cables is the #1 cause of encoder signal dropouts. Derul's encoder cables feature aluminum foil + tinned copper braid double shielding (≥85% coverage) with a dedicated drain wire. Power cables use a single high-coverage tinned copper braid. The result: stable, noise-free feedback signals even in dense control cabinets and cable trays shared with high-power motor leads.
The DERUL-SV series covers the complete servo connection:
Power Cable: 4-core UVW motor phase + PE ground (optional brake pair)
Encoder Cable: 4/6/8/10-core twisted pair, double shielded, with drain wire
Standard orange jacket follows global servo industry color coding for instant identification on the factory floor. Both cables are cut-to-length on reels — ready for connector termination at your end.
CNC machine tools flood cables with cutting oil, coolant, and metal chips. Standard PVC jackets swell, harden, and crack within weeks. Derul's premium PUR (polyurethane) jacket is tested to IRM 902 oil resistance standards and resists:
Cutting oils and water-miscible coolants
Hydraulic fluids and grease
Metal swarf abrasion
Hydrolysis from high-humidity environments
UV exposure for outdoor gantry applications
Every servo drive brand has different pinouts. Derul Cable configures to your exact specification:
Power cable: 4C, 4C+2, 5C, or custom — specify UVW, PE, and brake wire counts
Encoder cable: twisted pairs with individual pair shielding — specify number of pairs and drain wire
AWG: 26 to 12 AWG, matched to motor wattage
Connector termination: bare ends, stripped and tinned, or pre-terminated with your connectors
Length: 50 m / 100 m / 200 m / 500 m reels — or pre-cut assemblies
With 4,000 m² of specialized production space and ISO 9001 certified manufacturing, Derul Cable eliminates the middleman. Every DERUL-SV reel undergoes:
100% continuity + hipot testing (2,500 V)
Insulation resistance check
Shield continuity verification
Dimensional inspection
5–7 day sampling with free technical consultation from cable engineers who understand servo systems.
