Industrial Cables

Industrial cables are pre-assembled, bulk wiring assemblies that carry power, signals, and data between drives, motors, sensors, controllers, and network infrastructure throughout an automation system. PLC Direct stocks industrial cable products from Siemens and Turck, including motor and drive signal cables, PROFINET network cables, and sensor connectivity wiring, available as surplus sealed, refurbished, and used hardware.

Where are Industrial Cables used in industrial environments?

Industrial cables are used at every physical connection point in a control system, from the encoder interface between a servo motor and its drive to the Ethernet run between a PLC and a managed switch. Replacement cables are most commonly needed in drive and motion systems, where cable failure or physical damage at a connector or along a cable carrier run takes a machine offline until the exact assembly is sourced.

Facilities and operations that depend on industrial cables include:

CNC machining centers and turning cells using Siemens SINUMERIK and SINAMICS systems, where damaged or worn MOTION-CONNECT encoder and DRIVE-CLiQ signal cables between motor modules and spindle or axis motors must be replaced to restore machining capability.

Packaging and converting lines running SINAMICS S120 multi-axis drive topologies, where MOTION-CONNECT 800PLUS trailing-type cables in drag chains require periodic replacement due to flex fatigue over high-cycle operation.

PROFINET network installations requiring Siemens Industrial Ethernet FC cable to extend or repair permanent structured cabling runs between controllers, switches, and distributed I/O stations across a production facility.

Machine builders assembling servo drive panels who need pre-assembled MOTION-CONNECT signal cables at specific lengths to connect SINAMICS V90 drives to 1FL6 servo motors without field termination.

Automated assembly and material handling systems using Turck M12 sensor cabling to connect distributed proximity, photoelectric, and pressure sensing devices to field I/O modules across machine frames and conveyor systems.

A damaged or failed cable in a servo drive or encoder circuit immediately disables the affected axis or machine, making exact part number, connector type, and cable length matching essential before ordering a replacement.

Which brands of Industrial Cables does PLC Direct stock?

Industrial cables include Siemens and Turck across four product families.

Siemens MOTION-CONNECT 300 Series: Pre-assembled signal cables for SINAMICS V90 incremental encoder connections, rated for standard fixed installation and available in defined lengths with UL/CSA approval.

Siemens MOTION-CONNECT 800PLUS Series: High-flex trailing-type signal and DRIVE-CLiQ cables for SINAMICS S120 motor modules and SINUMERIK systems, rated for continuous drag-chain and cable-carrier applications with extended flex life.

Siemens Industrial Ethernet FC Series: Shielded PROFINET Type A twisted-pair cables for permanent Industrial Ethernet installation, including bulk cable sold by the meter and pre-assembled antenna connection cables for IWLAN infrastructure.

Turck Sensor and Connectivity Series: Industrial M12 and multi-pole sensor cables, cordsets, and field-wiring connectivity components for connecting proximity sensors, actuators, and block I/O modules in machine-level automation environments.

PLC Direct stocks industrial cables as surplus sealed, refurbished, and used hardware, depending on available inventory.

What should you know before ordering Industrial Cables?

Hardware condition options: Surplus sealed cables are unused and in original manufacturer packaging. Refurbished cables have been inspected and restored to serviceable condition. Used cables are tested functional assemblies, with the condition stated on each product listing.

Compatibility and part identification: Pre-assembled industrial cables are matched by connector type, cable designation, and exact length. For MOTION-CONNECT cables, the part number encodes all three, and ordering a different length or connector variant will produce an assembly that cannot be installed as a direct replacement. For DRIVE-CLiQ cables, the installed length must also remain within the maximum specified length for the drive topology, as longer cables can introduce signal integrity issues that prevent axis initialization.

Warranty: All industrial cable hardware purchased from PLC Direct carries a standard 1-year warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products. PLC Direct supplies industrial cable hardware for replacement and maintenance purposes and does not provide system design, programming, or integration services.

Frequently asked questions

MOTION-CONNECT 300 cables are designed for standard fixed installation where the cable does not move during operation. MOTION-CONNECT 500 cables support limited flexing and are suitable for applications with occasional movement. MOTION-CONNECT 800PLUS cables are high-flex trailing-type assemblies rated for continuous drag-chain and cable-carrier operation, with a significantly higher bend cycle rating than the 300 or 500 families.

The last segment of a MOTION-CONNECT part number contains a four-digit length code, where each digit position represents a length increment in meters. For example, a suffix of 1AF0 decodes to a specific meter value based on the position weighting defined in the Siemens ordering documentation for that cable type. The exact decoding table is available in the relevant SINAMICS or MOTION-CONNECT catalog, and confirming the encoded length against the installed cable before ordering is strongly recommended.

Pre-assembled MOTION-CONNECT cables use factory-fitted connectors that are not designed for field re-termination. Cutting a pre-assembled cable and fitting a new connector on site is not supported by Siemens and would void any applicable warranty. If the required length is not available as a stocked assembly, the nearest available length or a custom-assembled cable from a qualified supplier is the appropriate solution.

Siemens specifies a maximum DRIVE-CLiQ cable length for standard installations, with certain pre-assembled variants rated to a shorter maximum as noted in the product description. Exceeding the specified length can cause communication faults during drive startup or intermittent signal errors during operation. The installed cable length, including any routing allowance, should be confirmed against the product specification before ordering a replacement.

Siemens IE FC TP cable meets Cat 5E electrical specifications and is electrically compatible with standard Ethernet, but it is specified and priced for industrial installations where shielding, temperature range, and oil or chemical resistance matter. Using it for office cabling is technically possible, but it's not its intended application; standard Cat 5E or Cat 6 structured cabling products are more cost-effective for office environments.
