What this page covers
What does Industrial Automation & Control cabling include?
It covers the cable routes between PLCs, field devices, machines and control cabinets.
Industrial automation wiring is not one cable type. A complete project may require serial communication cable, industrial Ethernet cable, protocol-specific fieldbus cable, sensor and actuator cable, shielded control cable and cabinet wiring products. The right selection depends on communication protocol, EMI exposure, fixed or moving route, oil and abrasion risk, cabinet layout, termination method, labeling and packing.
01 Communication layer: RS485 / RS232, PROFINET and fieldbus links between controllers, drives, meters and I/O modules.
02 Device layer: sensor, actuator, valve and limit switch wiring where jacket material and bending stress matter.
03 Cabinet layer: PLC panel, relay cabinet, terminal box and equipment enclosure cabling with clear BOM and labeling.
5 solution paths RS485 / RS232, PROFINET, Fieldbus, Sensor & Actuator and Control Cabinet cabling.
Project-first selection Choose by protocol, route, shielding, jacket, flexibility, cabinet layout and procurement conditions.
BOM-ready support Suitable for machine builders, panel builders, system integrators, distributors and project buyers.

How do automation areas map to cable families?
| Automation Area | Typical Application | Recommended ZION Products | Key Selection Point |
|---|---|---|---|
| PLC Serial Communication | PLC, meter, drive, controller, HMI and remote device wiring | RS485 / RS232 Communication Cable | Protocol, impedance, pair count, shielding, route length and termination method |
| Industrial Ethernet | PLC, drive, I/O block, industrial switch, robot and machine network | PROFINET Cable, Industrial Ethernet Cable | Type A / B / C, fixed or flexible route, shielding and connector planning |
| Fieldbus Network | PROFIBUS-DP, CANBus, DeviceNet, CC-Link and INTERBUS routes | Fieldbus Cable | Protocol matching, topology, impedance, termination and labeling |
| Machine Device Wiring | Sensors, actuators, valves, limit switches and I/O modules | Sensor & Actuator Cable | PVC / PUR, shielded / unshielded, oil resistance and bending stress |
| Control Cabinet Wiring | PLC panels, relay cabinets, terminal boxes and control enclosures | LiYY, LiYCY, YY and CY Control Cable | Shield need, conductor count, voltage, route separation and labeling |
| Harsh Industrial Route | Machine movement, oil, abrasion, EMI or protected outdoor-like exposure | PUR Cable, Shielded Cable, Flexible Control Cable | Jacket material, flexibility, shielding and mechanical protection |
Engineer’s shortcut
Which cable direction is safer for each project condition?
| Project Condition | Recommended Direction | Risk Focus |
|---|---|---|
| PLC to meter, drive or controller serial communication | RS485 / RS232 Communication Cable | Confirm protocol, RS485 impedance wording, shield, pair count and termination |
| Factory Ethernet for PLC, drive, I/O and robot networks | PROFINET Industrial Ethernet Cable | Choose Type A / B / C by fixed, flexible or high-flex route |
| Existing machine uses PROFIBUS, CANBus or DeviceNet | Fieldbus Cable Solution | Do not mix bus families without engineering review |
| Sensor wiring near motors, drives or power cable routes | Shielded Sensor & Actuator Cable | EMI interference, route separation and shield grounding |
| Machine-side route with oil, abrasion or repeated movement | PUR Sensor & Actuator Cable or Flexible Control Cable | PVC may not survive harsh machine-side conditions |
| PLC cabinet internal control wiring | LiYY / YY Control Cable | Conductor count, color, voltage, terminal plan and cabinet labeling |
| Signal wiring inside a noisy control cabinet | LiYCY / CY Shielded Control Cable | Screened cable helps reduce interference when grounding is planned correctly |
| Distributor stock planning for industrial projects | Standardize cable family, print and packing length | Avoid unclear labels, mixed construction and repeated BOM revisions |
Risk control
Why do industrial cable projects fail after installation?
Wrong protocol cable Fieldbus, RS485 and industrial Ethernet routes should not be selected only by conductor count or jacket color.
Shielding without grounding plan Shielded cable helps only when route separation, grounding and termination are handled correctly.
Fixed cable used in moving route Machine movement, cable carrier routes and repeated bending require a different flexibility discussion.
Unclear cabinet BOM Panel wiring needs conductor count, color, voltage, labeling, terminal plan and packing control.
For engineers
Confirm protocol, cable route, EMI exposure, bending radius, moving or fixed installation, and cabinet drawing before selecting the cable family.
For procurement teams
Ask for a clear cable schedule with construction, print, packing, quantity, documents and approval requirements before placing orders.
For distributors
Standardize common RS485, PROFINET, fieldbus, sensor and cabinet cable ranges to reduce repeated small-order complexity.

FAQ
Industrial Automation & Control Cabling FAQ
RS485 cable is used for serial communication between devices such as PLCs, meters, controllers and drives. PROFINET cable is used for industrial Ethernet communication between PLCs, I/O modules, drives, switches, robots and machine networks. They should not be selected interchangeably.
Yes. You can send the cable schedule, protocol list, route length, cabinet drawing, packing requirement and quantity estimate to ZION Sales Support for selection review and quotation discussion.
MOQ depends on the cable family, conductor construction, shielding, jacket material, print, packing and customization requirement. ZION Sales Support can confirm the practical MOQ after reviewing the target specification.
Sample support can be discussed based on product availability, cable construction and project requirement. For custom constructions, sample feasibility should be confirmed with the sales and production team first.
ZION can provide applicable datasheets and available technical documents for relevant products. If a project requires specific test reports or compliance documents, confirm the requirement before purchase order and production.
Custom cable marking, jacket color, packing length, carton label, drum label and OEM / ODM discussion can be supported depending on product family, quantity and production feasibility.
Shielded cable is recommended when signal or communication routes are close to motors, drives, power cables or noisy cabinet areas. Selection should also include grounding method, route separation and termination planning.
PUR cable should be considered when the route may face oil, abrasion, mechanical stress or repeated movement. PVC cable may be suitable for protected routes, but the final choice should match the installation environment.
Fieldbus cable selection should match the protocol and system requirement. PROFIBUS-DP, CANBus, DeviceNet, CC-Link and other systems may require different construction, impedance, shielding or conductor configuration.
Panel builders should confirm conductor count, conductor size, voltage, shielded or unshielded route, cable color, terminal plan, cabinet drawing, route separation, label method and packing length.
Yes. Distributors can discuss standard cable families, common packing lengths, private label requirements, sample kits and recurring project supply with ZION Sales Support.
Delivery time depends on product family, specification, quantity, customization, packing and production schedule. The sales team can confirm the estimated delivery plan after the final specification and quantity are clear.
Need product selection support for an automation cable BOM?
Send your protocol list, cable schedule, control cabinet drawing, route length, shielding requirement, jacket preference, packing request and quantity estimate. ZION can help review the cable direction before quotation, sampling or project supply discussion.
