Connecting Every Level of Industrial Automation
An automated machine does not fail only when a controller, motor or sensor stops working. In many systems, the cable is the only component that must continuously carry power, feedback signals and high-speed data while bending, twisting or operating around heat, oil and electromagnetic interference.
A cable may satisfy the required voltage and conductor size but still become the weakest point in the system if its mechanical construction does not match the application. HULK evaluates cables according to where they operate, what they transmit and how they move.
Control and Power Distribution
Cables connect PLCs, relays, power supplies, drives, terminal blocks and other cabinet components responsible for machine control and power distribution.
Industrial Communication
Network cables carry production data and control commands between controllers, HMIs, drives, remote I/O modules and connected machines.
Sensors and Field Devices
Compact signal and power cables connect proximity sensors, photoelectric sensors, encoders, valves, actuators and IO-Link devices throughout the equipment.
Drives and Moving Systems
Cables supplying motors, moving axes, drag chains and robots must tolerate repeated bending, acceleration, torsion and constantly changing mechanical loads.

Discuss a Custom CableBuilt for the Equipment That Keeps Production Moving
Different types of automation equipment place different demands on their cables. HULK develops cable solutions around the actual motion, communication and environmental conditions of each machine.
Automated Assembly and Production Lines
Assembly stations depend on synchronized power, control and feedback connections across transfer modules, positioning systems and repetitive production processes.
Packaging and Processing Machinery
High operating speeds, frequent acceleration, compact routing and exposure to cleaning agents or temperature changes must be considered in filling, sealing, labeling and packaging equipment.
CNC Machines and Motion Platforms
Machine tools combine moving axes, servo drives, spindle motors, tool changers and industrial communication systems in environments where oil, coolant, vibration and electromagnetic interference may be present.
Robotics and Pick-and-Place Cells
Industrial robots, SCARA systems and collaborative robots require cables that tolerate changing bend directions, torsion and tightly controlled routing around multiple joints.
Conveyors and Automated Warehousing
Conveyors, sorting systems, automated storage equipment and long-travel handling systems need reliable connections across distributed motors, sensors and control devices.
Machine Vision and Inspection Systems
Industrial cameras, lighting systems, sensors and controllers rely on stable signal and data transmission to support precise inspection, measurement and production decisions.
Start With the Application, Not the Part Number
Selecting an industrial automation cable begins with understanding how it will operate inside the machine. A technically accurate recommendation normally requires the following information.
| Requirement | Information to Provide | Why It Matters |
|---|---|---|
| Electrical function | Power, control, feedback, sensor signal or data transmission | Determines conductor, insulation, shielding and electrical construction |
| Electrical load | Voltage, current, conductor cross-section and conductor count | Helps define conductor sizing and insulation requirements |
| Movement profile | Fixed, occasional flex, drag-chain movement, torsion or combined motion | Determines whether a standard flexible, high-flex or torsion construction is required |
| Motion parameters | Travel distance, speed, acceleration, cycles and torsion angle | Influences conductor stranding, cable lay and material selection |
| Routing geometry | Available space, cable outer diameter, bend radius and installation orientation | Helps prevent excessive mechanical stress and routing problems |
| Communication system | Protocol, cable category, impedance and required data rate | Determines the necessary electrical geometry and shielding |
| Environment | Temperature, oil, coolant, chemicals, UV, abrasion or cleaning exposure | Determines insulation and jacket material |
| Compliance | Target market, flame requirement, halogen requirement and certification | Ensures the design addresses applicable market requirements |
| Commercial details | Required length, reel size, marking, quantity and target delivery date | Supports accurate sampling, production and quotation planning |
Engineering Against Common Cable Failure Risks
Automation cable failures are often caused by several operating conditions acting together. Understanding the failure mechanism is essential when selecting or customizing the cable.
Conductor Fatigue
Repeated bending can gradually damage conductor strands, particularly when the bend radius or cable construction is unsuitable for the motion. Fine-stranded conductors and a controlled internal lay help distribute mechanical stress.
Shield Fatigue and Signal Interference
Servo drives and motors can generate electromagnetic interference, while repeated movement can place mechanical stress on the shield. Shielding must provide both electrical performance and sufficient flexibility for the application.
Unstable Industrial Communication
Excessive bending, poor shielding or changes in internal cable geometry can affect impedance and signal integrity. Industrial network cables must maintain their required electrical characteristics during operation.
Corkscrewing and Core Displacement
Improper routing, excessive torsion or an unsuitable internal construction can cause the cable to twist, deform or push internal cores out of position. Multi-axis applications require a torsion-specific design.
Jacket Cracking, Swelling or Abrasion
Heat, oil, coolant, cleaning chemicals and continuous contact with the cable carrier can degrade an unsuitable jacket. Material selection should be based on the actual exposure rather than a general resistance claim.
Excessive Mechanical Stress
Installing a cable below its specified bend radius, overfilling the cable carrier or mixing cables with incompatible sizes can shorten service life even when the cable itself is correctly designed.
From Application Requirement to Production-Ready Cable
Automation equipment manufacturers frequently need a cable that combines several requirements, such as servo power, encoder feedback, continuous flexing, compact diameter, oil resistance and market-specific compliance.
HULK works with engineering and purchasing teams to convert these requirements into a controlled, manufacturable specification.
