ZION flex control cables cover LiYY and LiYCY data cable constructions plus YY, CY and SY control cable families for industrial control, measuring and signal connections. Select by conductor size and core arrangement, copper-braid screening, PVC or LSZH jacket, mechanical protection, voltage rating, temperature range and permitted bend radius.
Start with the required electrical and mechanical construction. LiYY and YY are unscreened options; LiYCY and CY add tinned-copper braid screening; SY adds galvanised steel-wire braid for mechanical protection. PVC and LSZH variants address different installation and fire-performance specifications.

A reliable selection starts with signal sensitivity and installation stress, then confirms conductor size, core or pair arrangement, jacket, voltage, temperature and bend radius. Do not use the family name alone as a complete specification.
Choose unscreened LiYY or YY only when the route and noise environment permit it. Choose LiYCY or CY with a tinned-copper braid where interference control is required, and define the bonding method in the installation specification.
State core count or pair count, conductor cross-section in mm² and whether twisted pairs are required. LiYY TP and LiYCY TP arrange cores as pairs for control, measuring and signal circuits.
Select the jacket against the project fire, smoke and halogen requirements. ZION's listed LSZH YY, CY and SY products reference IEC/EN 60754-1/2 and IEC/EN 61034-1/2; confirm the exact project requirement at RFQ.
Choose SY when a galvanised steel-wire braid is needed for light mechanical protection. Steel braid is not a substitute for the tinned-copper screening used in CY or LiYCY when EMI control is the main requirement.
Check the model-specific fixed and flexed bend radius. The listed values describe allowable installation geometry; they do not by themselves confirm continuous drag-chain or torsional service.
Confirm circuit voltage, ambient temperature, indoor or outdoor route, moisture, oil or chemical exposure and tensile load. Several listed YY products are explicitly not intended for outdoor or underground installation.
Use this table to narrow the family, not to replace the final datasheet review. Bend radius is expressed as a multiple of the cable overall diameter, d.
| Model | Screen / Armour | Jacket | Voltage | Temperature, Fixed / Flexed | Min. Bend, Fixed / Flexed | Selection Direction |
|---|---|---|---|---|---|---|
| LiYY | Unscreened | PVC | Max. 350 V below 0.25 mm²; max. 500 V at or above 0.25 mm² | -30 to +70 °C / -5 to +70 °C | 5 × d / 10 × d | Electronic device, computer-system and process-control signal links |
| LiYCY TP | Paired construction; confirm screen details for the selected version | PVC | Max. 350 V below 0.25 mm²; max. 500 V at or above 0.25 mm² | -30 to +70 °C / -5 to +70 °C | 5 × d / 10 × d | Paired control, measuring and signal circuits in dry or humid rooms |
| YY PVC | Unscreened | PVC | 300/500 V | -40 to +80 °C / -5 to +70 °C | 4 × d / 12.5 × d | Indoor instrumentation, machine tools and production-line control |

| CY PVC | Tinned-copper wire braid | PVC | 300/500 V | -40 to +80 °C / -5 to +70 °C | 4 × d / 12.5 × d | Control connections where high-frequency interference must be reduced |
| SY PVC | Galvanised steel-wire braid armour | Transparent PVC | 300/500 V | -40 to +80 °C / -5 to +70 °C | 4 × d / 12.5 × d | Interconnection requiring light mechanical protection |
Flex control cable is commonly selected around PLC I/O, instrumentation, sensors, production equipment and control panels. The correct family depends on circuit function, the nearby noise source and the cable's actual movement and environment.
YY or LiYY can suit indoor control circuits when routing and EMI conditions allow. Specify core count, cross-section, voltage and segregation from power conductors.
Where switching noise can couple into control or feedback wiring, assess CY or LiYCY and document shield termination. Cable screening cannot correct poor routing, bonding or cabinet grounding.
Confirm whether the circuit requires paired conductors and screening. A TP construction can organize signal pairs, but protocol, impedance and device compatibility still require separate verification.
YY, CY or SY may be shortlisted according to EMI and mechanical risk. For repeated flexing, drag chains, torsion or tensile load, request a construction explicitly approved for that duty.
Consider the verified LSZH variants when the project specification addresses smoke and halogen emissions. Match the exact IEC/EN tests and local code requirements before purchase.
Do not assume suitability from the cable family name. The listed YY products exclude outdoor and underground installation, while SY PVC requires protection from direct sunlight; request a verified alternative when needed.
YY is unscreened, CY uses a tinned-copper braid screen for interference control, and SY uses galvanised steel-wire braid armour for mechanical protection. Confirm the exact model because jacket, temperature and bend-radius values vary.
A copper-braid screened family is the appropriate starting point when EMI is a concern, but final selection depends on the signal, route and equipment requirements. Define cable separation, screen termination and grounding with the system design.
No. A published flexed bend radius does not confirm continuous drag-chain, torsional or robotic duty. Provide the motion cycle, travel distance, speed, acceleration and bend radius so ZION can confirm a suitable construction.
Specify LSZH when the project requires verified low-smoke and halogen performance. Do not treat LSZH as a universal upgrade: confirm the applicable IEC/EN tests, local code, environment and mechanical requirements.
First check routing near power cables and drives, shield continuity and termination, grounding, connector quality, bend damage and conductor continuity. Confirm that the selected cable matches the signal type and environment before replacing it with another family.
Yes, replacement selection can begin from the existing datasheet and installation conditions. Provide conductor size, core or pair count, voltage, screen or armour, jacket, outside diameter, bend radius, temperature range, standards and application details; equivalence must be confirmed before ordering.
A complete RFQ helps ZION confirm the construction, identify an existing model or evaluate an OEM or replacement requirement without avoidable quotation cycles.
