About This Product
Flexible Control Wiring With EMC Screening for Industrial Automation
Shielded Flexible Control Cable is the screened member of the flexible control-cable family used for machine interconnection, PLC I/O circuits, sensor and actuator wiring, instrumentation panels, and automated production equipment. In European catalogues it is commonly sold as CY or JZ-CY; when manufactured and certified to the harmonised oil-resistant PVC control-cable standard, the designation is H05VVC4V5-K under EN 50525-2-51. In signal and instrumentation ranges, related names include LiYCY; in Chinese-style product lists, RVVP is the common screened PVC flexible control/signal designation.
The defining feature is the overall metallic screen, usually a tinned copper wire braid and sometimes combined with foil and a drain wire. The screen reduces electromagnetic interference coupling into low-level control signals and helps contain noise generated by switching equipment nearby. It is not a substitute for a protective earth conductor, mechanical armour, or a VFD motor-output EMC cable. Correct screen termination and routing are just as important as the cable construction itself.
For global customers, the safest purchasing language is to state the required standard and construction instead of relying on one regional nickname. A typical industrial order might specify: CY / H05VVC4V5-K, 300/500V, Class 5 copper, numbered PVC cores, overall tinned copper braid screen, PVC or oil-resistant PVC sheath, flame test to IEC 60332-1-2, supplied with test report and declaration of conformity. If the project uses LiYCY or RVVP, the voltage rating, conductor size, colour code, screen coverage, sheath compound, and approval marks must be confirmed on the actual datasheet.
Cable Structure
Fine-Strand Conductors, PVC Core Insulation, Overall Screen, Protective Sheath
The standard construction is built for flexible control wiring rather than heavy power distribution. It combines fine-strand copper conductors for handling, PVC insulation for compact multi-core cabling, an overall screen for EMC performance, and a PVC or oil-resistant PVC outer sheath for indoor industrial environments.
-
1
Conductors — IEC 60228 Class 5 Copper
Fine-stranded annealed copper conductors provide the flexibility needed for machine wiring and panel-to-equipment connection. Bare copper is standard for many CY ranges; tinned copper can be specified for improved corrosion resistance or for particular instrumentation designs. Typical industrial control sizes are 0.5, 0.75, 1.0, 1.5, and 2.5 mm².
-
2
Core Insulation — PVC, Numbered or Colour-Coded
PVC insulation is compact and economical for multi-core control wiring. European CY / H05VVC4V5-K cables commonly use black numbered cores with a green-yellow protective conductor in G-type constructions. LiYCY-style cables often use DIN 47100 colour coding for signal identification. The exact core marking should match the machine wiring diagram and customer standard.
-
3
Overall Screen — Tinned Copper Braid or Foil + Drain
The screen is applied over the laid-up insulated cores. A tinned copper braid is the normal CY construction because it gives good EMC performance while remaining flexible. Foil screens with a drain wire are common on LiYCY or instrumentation variants where small outer diameter and easy termination matter. Screen coverage and transfer impedance are datasheet values and should be specified for EMC-critical equipment.
-
4
Outer Sheath — PVC or Oil-Resistant PVC
The outer sheath protects the screen and cores from normal workshop abrasion, oils, and handling. EN 50525-2-51 harmonised H05VVC4V5-K cables use oil-resistant PVC sheathing. Standard sheath colour is usually grey for European control cables and black for many RVVP ranges; orange, blue, or custom printing can be quoted for machine builders and OEM projects.
Key Features
EMC Protection Without Moving Into Heavy Power Cable Territory
Shielded flexible control cable is selected when ordinary YY or unshielded PVC control cable is electrically too exposed, but a heavy armoured cable or a purpose-built VFD motor cable would be the wrong product. The value is compact multi-core control wiring with a practical EMC screen.
Overall EMC Screen
A tinned copper braid or foil screen reduces interference pickup in control and signal circuits, especially around contactors, relays, servo drives, and inverter-fed equipment. For best results, the screen must be terminated correctly and bonded according to the equipment EMC plan.
Flexible for Machine Wiring
Class 5 fine-strand copper makes the cable easier to route through panels, cable trays, and machine frames than solid or Class 2 conductors. It is suitable for occasional movement and free movement without tensile stress, but standard CY is not a continuous drag-chain cable.
Many Core Counts Available
Multi-core constructions from simple 2-core signal links to high-core-count PLC wiring reduce installation time and make cabinet wiring cleaner. Numbered cores are preferred for machine builders because they map directly to terminal blocks and wiring diagrams.
300/500V Control-Circuit Range
CY and H05VVC4V5-K control cables are commonly specified at 300/500V for low-voltage control and machine interconnection. LiYCY and RVVP versions may use different ratings, so voltage must be confirmed from the datasheet before substituting one designation for another.
Standards Can Be Matched by Market
For European machinery, H05VVC4V5-K under EN 50525-2-51 is the cleanest specification. For global OEMs, CY, LiYCY, or RVVP can be quoted with equivalent construction details, test reports, and requested flame, oil, RoHS, REACH, CE, or third-party documentation.
Economical EMC Upgrade From YY
Compared with unshielded YY cable, CY adds an EMC screen while keeping a familiar PVC control-cable format. It is cost-effective for automation builders who need noise immunity but do not need steel wire braid armour, halogen-free fire performance, or high-flex robotic cable construction.
How to Choose
Six Decisions Before You Specify a Shielded Control Cable
The most common mistake is ordering by nickname only. CY, LiYCY, RVVP, and H05VVC4V5-K overlap in application but do not automatically share the same voltage rating, screen design, sheath compound, approval, or colour code. These six decisions make the quotation technically clear.
Confirm the electrical role
Use shielded flexible control cable for control voltage, signal, instrumentation, and machine interconnection circuits. Do not use it as a motor-output cable from a variable-frequency drive unless the drive manufacturer explicitly accepts that construction. VFD outputs normally need a dedicated symmetrical EMC motor cable.
Choose CY / H05VVC4V5-K / LiYCY / RVVP deliberately
H05VVC4V5-K is the most precise request for harmonised European screened PVC control cable at 300/500V. CY is the common commercial name. LiYCY is often better for compact data, measuring, and signal wiring. RVVP is common in China and export supply but needs a defined standard and rating on the purchase order.
Select core count and conductor size from the wiring diagram
Typical PLC and machine-control sizes are 0.5, 0.75, 1.0, 1.5, and 2.5 mm². Choose core count from the terminal schedule, not by guesswork. Include spare cores if the machine builder expects future I/O expansion, but avoid oversized high-core-count cable if the cabinet has tight glands or small bending space.
Specify the screen type and termination plan
Tinned copper braid is robust and flexible for CY control cable. Foil plus drain wire is easier to terminate for small signal cables. For EMC-sensitive equipment, ask for screen coverage or transfer-impedance data and define whether the screen is bonded 360° at both ends, single-ended, or through EMC glands according to the equipment design.
Check the environment
Standard PVC control cable is mainly for indoor industrial use. If the cable faces coolant, cutting oil, sunlight, low temperature, outdoor weather, washdown, welding spatter, or continuous flexing in a cable chain, specify the appropriate oil-resistant, UV-resistant, PUR, LSZH, or drag-chain-rated variant instead of assuming standard CY will survive.
State required documents and markings
For export projects, list the exact documents needed: EN 50525-2-51 declaration, IEC 60228 conductor confirmation, IEC 60332-1-2 flame test, RoHS / REACH, CE declaration, factory test report, COO, or third-party inspection. If OEM sheath printing is required, provide the exact legend, metre marking requirement, and language before production.
Applications
Where Shielded Flexible Control Cable Is the Right Choice
The cable is designed for low-voltage control and signal wiring where electromagnetic noise is a realistic problem. It is especially valuable in factories where power wiring, drives, solenoids, relays, and control circuits share crowded machine spaces.
Machine Tools & CNC Equipment
Control circuits for CNC machines, milling equipment, lathes, presses, and auxiliary machine functions. The screen helps protect control wiring from nearby servo drives, contactors, pumps, and switching devices inside the machine enclosure.
PLC I/O & Control Cabinets
Numbered multi-core cables simplify wiring between PLC cabinets, terminal boxes, remote I/O stations, and machine modules. Shielded versions are used when signal integrity is more important than the lowest possible cable cost.
Packaging & Production Lines
Conveyors, packaging machines, filling lines, bottling lines, and light assembly equipment use screened control cable for sensors, limit switches, solenoids, interlocks, and auxiliary control wiring in electrically noisy industrial spaces.
Instrumentation & Building Controls
HVAC controls, measurement loops, cabinet instrumentation, and general low-voltage control circuits can use LiYCY or CY-style screened cable where the signal is vulnerable to external electromagnetic interference.
Not appropriate for: VFD motor output unless a dedicated EMC motor cable is specified. Continuous drag-chain motion unless the cable is designed and tested for chain service. Outdoor UV exposure unless UV-resistant sheath is confirmed. Heavy mechanical impact where SY or armoured cable is required. Fire survival circuits, mining equipment, welding leads, submersible pumps, or permanent building power feeders unless a separate compliant cable type is selected.
Technical Data
Shielded Flexible Control Cable Selection Reference
The values below are a specification guide, not a substitute for the final datasheet. Exact outside diameter, copper weight, screen coverage, current rating, and bending radius depend on core count, conductor size, screen construction, sheath compound, and certification route.
| Item | Typical Specification | Engineering Note |
|---|---|---|
| Product names | CY, JZ-CY, H05VVC4V5-K, LiYCY, RVVP | Names overlap by market; construction and standard must be written on the PO. |
| Rated voltage | 300/500V common for CY / H05VVC4V5-K | LiYCY and RVVP ratings vary by series and cross-section; confirm datasheet. |
| Conductor | IEC / EN 60228 Class 5 flexible copper | Bare copper standard; tinned copper available for selected ranges. |
| Cross-section | 0.5 to 2.5 mm² common; larger on request | Use 0.5 / 0.75 mm² for light I/O, 1.0 / 1.5 mm² for control power, 2.5 mm² where voltage drop or load requires. |
| Core count | 2 to 61 cores depending on range | G-type includes green-yellow earth; X-type has no green-yellow core. |
| Core identification | Numbered black cores or DIN 47100 colours | Numbered cores suit machine builders; colour-coded cores suit signal/data wiring. |
| Screen | Overall tinned copper braid or foil + drain wire | Specify braid coverage or transfer impedance for EMC-critical projects. |
| Insulation / sheath | PVC / PVC, oil-resistant PVC where required | PUR, LSZH, UV-resistant, or cold-flex compounds require separate quotation. |
| Operating temperature | Typical PVC range around -5°C to +70°C in flexing service | Cold-rated or fixed-installation ranges differ by compound and certification. |
| Bending radius | Often 6× OD fixed, 10× OD flexing as a planning rule | The final datasheet governs; drag-chain service needs a chain-rated cable. |
| Flame behaviour | IEC / EN 60332-1-2 if specified | Do not assume LSZH or fire survival performance from standard PVC CY cable. |
| Packaging | 100 m / 500 m / 1,000 m drums or coils | Cut lengths, metre marking, and OEM sheath printing available by quotation. |
For H05VVC4V5-K, specify EN 50525-2-51 and 300/500V only when the cable is actually manufactured and documented to that standard. For LiYCY / RVVP equivalents, request the datasheet and test report before substituting them into a project originally written around a harmonised European cable.
For EMC performance, installation quality matters: maintain screen continuity, avoid pigtail terminations where 360° bonding is required, keep noisy power cables separated from control circuits, and follow the equipment manufacturer’s grounding instructions.
Comparison
Choosing Between YY, CY, SY, and EMC Motor Cable
Control cable names are easy to confuse. The table below places shielded flexible control cable in the wider automation cable family so buyers can avoid under-specifying EMC protection or over-specifying mechanical protection.
| Attribute | CY / Shielded Flexible Control | YY / Unshielded Control | SY / Steel Wire Braid Control | VFD EMC Motor Cable |
|---|---|---|---|---|
| Primary purpose | Control and signal wiring with EMC screen | General control wiring where EMC is not critical | Control wiring with added mechanical protection | Motor output from inverter / VFD |
| Screen / braid | Copper braid or foil screen for EMC | No screen | Galvanised steel wire braid, mainly mechanical | Copper screen / symmetrical earths for drive EMC |
| Typical voltage | 300/500V for many CY / H05VVC4V5-K ranges | 300/500V common | 300/500V common | 600/1000V or drive-specific rating |
| Flexibility | Good for occasional movement | Good for simple routing | Lower flexibility because of steel braid | Depends on drive-cable construction |
| Best use | PLC I/O, machine control, instrumentation | Cabinet wiring, simple control circuits | Industrial control where abrasion risk is higher | VFD to motor cable runs |
| Not a substitute for | Armour, PE, or VFD motor cable | Screened cable in noisy circuits | True EMC screen unless designed as such | General high-core-count PLC cable |
| Buying caution | Specify screen type and standard | Check if noise immunity is needed | Check local code acceptance and termination | Follow drive manufacturer instructions |
When to choose shielded flexible control cable
Choose CY / H05VVC4V5-K / LiYCY / RVVP when the circuit is control, signal, measuring, or machine interconnection and the installation has realistic EMI exposure. It is the practical middle ground between cheap unshielded control cable and heavy specialised EMC power cable.
When to choose an alternative
Use YY when the environment is electrically quiet. Use SY or armoured cable where mechanical damage is the main risk. Use a dedicated VFD EMC motor cable for inverter outputs. Use PUR drag-chain cable for continuous motion. Use LSZH or fire-rated cable when the installation code requires low-smoke or circuit-integrity performance.
Frequently Asked Questions
Common Questions From Machine Builders and Automation Buyers
Is CY the same as H05VVC4V5-K?
Not automatically. CY is a common commercial name for screened flexible control cable. H05VVC4V5-K is a harmonised European designation for a screened, oil-resistant PVC control cable under EN 50525-2-51 at 300/500V. A CY cable can be offered as H05VVC4V5-K only if the construction, testing, and documentation match that standard.
Can I replace LiYCY or RVVP with CY?
Sometimes, but only after checking voltage rating, core identification, screen type, conductor size, sheath material, bending radius, and approvals. LiYCY is often used for compact signal/data control wiring and may have different colour coding or voltage rating. RVVP is a broad Chinese-style designation and must be tied to a specific construction and standard before substitution.
Can the screen be used as the protective earth?
No. The screen is for EMC and noise control. It must not be treated as the protective earth conductor unless a qualified design and applicable standard explicitly permits a specific construction, which standard CY / LiYCY / RVVP does not. If the circuit needs PE, specify a G-type cable with green-yellow core or provide a separate protective conductor.
Is it suitable for VFD motor output?
Usually no. VFD motor outputs produce high-frequency components and common-mode currents that need a drive-rated EMC motor cable with the correct screen, earth symmetry, insulation system, and voltage rating. CY is for control circuits around the drive, not normally for the drive-to-motor power output.
Can it be used in drag chains?
Standard CY is suitable for flexible installation and occasional movement, but not for continuous guided movement in a drag chain. For drag chains, specify a high-flex chain cable with tested bending cycles, suitable strand design, sliding sheath material, and manufacturer-approved minimum bend radius.
What information should I send for a quotation?
Send model or standard, voltage rating, core count, conductor size, G-type or X-type core arrangement, screen type, sheath material and colour, flame/oil/UV/LSZH requirements, order length, drum length, destination country, and required certificates. If replacing an existing cable, send a photo of the sheath marking or the original datasheet.
Installation & Handling Tips
Six Practices That Protect EMC Performance
A shielded cable can still perform poorly if it is routed or terminated badly. These practices help the installed system match the cable’s intended EMC function.
Use 360° screen bonding where required
For high-frequency EMC control, a long pigtail drain connection can reduce shielding effectiveness. Use EMC glands, shield clamps, or proper 360° bonding at the cabinet entry when the equipment grounding plan requires it.
Separate control and power routes
Do not run screened control cables tightly bundled with inverter output cables, welding cables, or large motor feeders. Use separate trays or maintain spacing; cross unavoidable power cables at right angles to reduce coupling.
Respect bend radius at glands and trays
Tight bends damage the screen and concentrate stress where the cable enters a gland. Use the datasheet bend radius; as a planning rule, allow more space for high-core-count screened cables than for unshielded YY of the same conductor size.
Do not put standard CY into continuous motion
Repeated chain movement can break fine copper strands and open the screen braid. If the cable moves every machine cycle, use a drag-chain-rated screened cable with the required bending-cycle data and cable-chain approval.
Match sheath to oil, coolant, and UV exposure
Standard PVC is not universal. Machine coolant, cutting oil, outdoor sunlight, and low-temperature bending can require oil-resistant PVC, PUR, UV-resistant, or cold-flex sheath compounds. Specify the environment before production rather than after a field failure.
Test continuity after termination
After pulling and gland termination, verify conductor continuity, insulation resistance, and screen continuity before commissioning. A damaged screen can be invisible under the sheath but still compromise EMC performance in the finished machine.
Safety note: Final cable selection must follow the electrical code, machinery standard, and EMC requirements of the destination market. The screen helps control interference but does not remove the need for protective earthing, overcurrent protection, correct gland bonding, and qualified installation practice.
