Power, Control and Data Across Material Handling Systems
From receiving and storage to picking, sorting and dispatch, an automated material handling system depends on many connections working together. Motors need reliable power. Sensors and actuators must report position and status without delay. Controllers, drives and distributed devices must exchange data consistently—even when equipment runs for long shifts or moves through thousands of cycles.
No single cable design is suitable for every connection point. A stationary conveyor motor may require a fixed or flexible motor cable, while a moving AS/RS axis may need a continuous-flex cable engineered for a defined travel distance, bend radius and acceleration. Communication links may also require shielding and construction matched to the protocol and motion profile.
Hulk Cable supports the four essential connection layers within material handling equipment:
Power Transmission:
Cables for motors, servo drives and powered conveyor sections.
Machine Control:
Multicore control cables for switching, command and auxiliary circuits.
Sensors and Actuators:
Flexible connections for detection, positioning and equipment feedback.
Industrial Communication:
Ethernet and fieldbus cables for controllers, drives, remote I/O and networked devices.
Where Our Cables Keep Materials Moving
Material handling equipment combines fixed wiring, repetitive linear motion and compact moving mechanisms. We configure cable solutions around the actual duty of each connection—not simply the name of the machine.
Conveyor and Sortation Systems
Belt, roller, overhead and cross-belt systems rely on distributed motors, sensors, encoders, scanners and control networks. Appropriate cable selection helps maintain dependable power and signal transmission through frequent starts, vibration and continuous production schedules.
AS/RS and Stacker Cranes
Automated storage and retrieval systems use horizontal and vertical travel axes, lifting units and positioning devices. Cables routed through moving carriers must accommodate the specified travel, speed, acceleration and bend radius while maintaining power, feedback and data performance.
Shuttle and Transfer Systems
Multi-shuttle systems, transfer cars and mobile storage mechanisms often combine rapid acceleration with restricted installation space. Compact, application-matched cables can support internal drives, lifting mechanisms, sensors and communication devices through repeated operating cycles.
Palletizers and Gantry Loaders
Palletizing cells and gantry handling systems depend on synchronized motors, feedback devices and control signals. Their cable requirements vary by axis: some connections remain fixed, others flex repeatedly, and rotating mechanisms may require designs suited to more complex movement.
AGV and AMR Onboard Systems
AGVs and AMRs may contain moving lift tables, roller decks, transfer modules and sensor assemblies. Flexible cables can support these onboard mechanisms where space is limited and repeated lifting, extension or positioning motion occurs.
Parcel and Baggage Handling
Parcel hubs and baggage handling systems combine long conveyor routes with sorters, scanners, diverters and distributed drive stations. Reliable power and industrial data connections help these high-throughput systems maintain accurate routing and reduce avoidable interruptions.
Operating Demands and Cable Design Responses
Cable service life depends on more than flexibility alone. The conductor, core arrangement, shielding, jacket and installation method must work together under the machine’s real operating conditions.
Continuous Flexing
Repeated bending can fatigue conductors and disturb the internal cable structure. Fine-stranded conductors, an optimized core lay and materials selected for dynamic use help the cable tolerate controlled repetitive movement.
Long Travel Distances
Long horizontal or vertical travel places additional mechanical demands on cables in carriers. Cable construction, carrier radius, installation, fill level and strain relief must be considered as one system.
Rapid Acceleration and Frequent Starts
Fast acceleration, deceleration and direction changes increase dynamic loading. A mechanically balanced cable construction helps keep the cores stable and reduces internal stress during repeated cycles.
Tight Installation Space
Compact equipment can force cables into small routing areas. Outside diameter, dynamic bend radius and carrier dimensions should be evaluated together rather than forcing a standard cable into an unsuitable path.
Electromagnetic Interference
Drives and motors can generate electrical noise that affects feedback and communication circuits. Pair or overall shielding, suitable core geometry and correct system-level shield termination help protect signal integrity.
Abrasion, Oil and Industrial Contaminants
Jacket material should match the environment. Depending on the application, Hulk can configure PVC, PUR, TPE, halogen-free or other application-specific constructions for the required flexibility and resistance profile.
Cable Solutions for Material Handling Equipment
Our material handling cable portfolio covers power, control, feedback and industrial communication. Final construction and performance are confirmed against the equipment’s electrical, mechanical and environmental requirements.
High-Flex Drag Chain Cables
Designed for controlled repetitive motion in cable carriers, high-flex cables can be configured for power, control, signal or data functions. Selection is based on travel, speed, acceleration, bend radius, cycle target and operating environment.
Servo and Motor Cables
Servo and motor cables connect drives with conveyor motors, positioning axes, lifting units and palletizing equipment. Shielded configurations are available where EMC performance, feedback integrity or drive compatibility requires them.
Sensor and Actuator Cables
Flexible sensor and actuator cables support photoelectric sensors, proximity switches, encoders, valves and other field devices. IO-Link-compatible variants can also be developed or selected for suitable applications.
Industrial Ethernet Cables
Industrial Ethernet cables support communication between controllers, drives, remote I/O, machine vision devices and other networked equipment. Options include PROFINET and Ethernet-compatible constructions, with flexibility and shielding selected for the installation.
Fieldbus Cables
Hulk manufactures fieldbus cable solutions compatible with protocols such as EtherCAT, DeviceNet, CANopen, PROFIBUS, CC-Link and AS-Interface. The correct impedance, shielding and motion rating are determined by the network and application.
Custom-Engineered Cables
When a standard construction does not fit, we can customize conductor size, core count, stranding, insulation, shielding, jacket material, color, marking and applicable certification requirements around your equipment design.

Frequently Asked Questions
What types of cables are used in material handling systems?
Material handling equipment may use motor and servo cables, control cables, sensor and actuator cables, industrial Ethernet cables, fieldbus cables and continuous-flex drag chain cables. The correct type depends on the connection’s electrical function, whether it remains fixed or moves, and the surrounding environment.
Which cable is suitable for a conveyor system?
There is no single cable for every conveyor. A stationary motor may use a fixed or flexible motor cable, while a moving transfer unit may require a continuous-flex construction. Sensors, encoders and network devices also need signal or data cables matched to their protocol, shielding and movement requirements.
Do AS/RS systems require continuous-flex cables?
Only connections that repeatedly move with a travel or lifting axis normally require continuous-flex cable. Stationary sections should use cable rated for their actual installation method. For a moving AS/RS connection, travel distance, speed, acceleration, carrier design, bend radius and cycle target should be reviewed together.
How do I determine the required bend radius?
Use the manufacturer’s minimum dynamic bend radius for continuously moving installations, not the fixed-installation value. The selected cable carrier radius must comply with that requirement. Cable outside diameter, travel speed, acceleration, available space and installation method should also be checked before final selection.
Can Hulk supply PROFINET, EtherCAT and other industrial communication cables?
Yes. Hulk offers industrial Ethernet and fieldbus solutions compatible with PROFINET, EtherCAT, DeviceNet, CANopen, PROFIBUS, CC-Link, AS-Interface and other industrial networks. We confirm the construction according to the protocol, data requirements, installation environment and required level of movement.
Can material handling cables be customized?
Yes. Hulk can customize conductor size, core count, stranding, insulation, shielding, jacket material, color, printing and applicable compliance requirements. Custom development is useful when an existing cable is failing, installation space is restricted or a machine requires combined electrical and mechanical characteristics.
What information should I provide for a cable recommendation?
Provide the equipment type, connection function, fixed or moving installation, travel distance, speed, acceleration, bend radius, cycle target, voltage, current, conductor size, communication protocol, environmental exposure and required certifications. An existing datasheet, drawing or cable sample is also helpful.
