About Wire and Cable

Coiled Extension Cords

These self-coiling cords return to their retracted length after stretching for tangle-free storage.

Abrasion-Resistant Turn-Lock Extension Cords

Thick insulation protects the internal wires of these cords, so they can be used in high-traffic areas and over rough surfaces.

Shielded Ethernet Cords

The shielding blocks signal interference from nearby equipment and devices.

DMX Cords

Commonly used for movie, stage, and interior building lighting, these cords connect to equipment with five-pin XLR connections.

Cable

Coiled Cable

After extending to full length to provide added reach, this cable retracts and self-coils for tangle-free storage. It's often used with hand tools and other portable devices.

High-Temperature Cable

For high-heat applications such as furnaces and ovens, this cable's insulation withstands temperatures of 390° F and higher.

Continuous-Flex Cable

Often used in automated applications such as robotics and cable carriers, this cable withstands continuous motion without degrading data or signal transmission.

Oil-Resistant Continuous-Flex Cable

The insulation has excellent resistance to oil, so this cable can be used near motors. Often used in automated applications, it withstands continuous motion without degrading data or signal transmission

Continuous-Flex and -Twist Robotics Cable

In addition to handling continuous movement, this cable withstands twisting up to 450° without degrading data or signal transmission. It's often used in welding robots and rotary tables.

Servomotor Continuous-Flex Cable

Connect servocontrollers and servomotors in automated equipment and on assembly lines. This cable withstands continuous motion without degrading data or signal transmission.

Long-Life Continuous-Flex Cable

With a life span of more than 20 million high-speed flex cycles, this cable lasts twice as long as standard continuous-flex cable. The frequent motion will not degrade data or signal transmission.

High-Voltage Continuous-Flex Flat Cable

Rated to 17,000 volts AC or higher, this cable is often used in oil drilling, robotics, and festoon systems. It withstands continuous motion without degrading data or signal transmission. The flat shape allows it to fit in tight spaces.

No-Conduit-Required Continuous-Flex Cable

Use this cable without conduit in automated applications—it meets crush and impact requirements for exposed runs in cable carriers, and withstands continuous motion without degrading data or signal transmission.

Communication and Security System Cable

Connect low-current circuits such as intercoms and security systems to a building's electrical system in single-level facilities.

Coiled Communication Cable

After extending to full length to provide added reach, this cable retracts and self-coils for tangle-free storage. It's often used with low-current circuits such as microphones and headsets.

No-Conduit-Required Control Cable

This cable meets TC-ER crush and impact requirements for exposed runs in cable trays, so it can be used without conduit. It sends signal and data to operate, measure, or regulate automated equipment.

Control Cable

Send signal and data to operate, measure, or regulate automated equipment such as conveyors and CNC machines.

Space-Saver Control Cable

Nearly two-thirds the diameter of standard control cable, this cable fits in tight spaces. It sends signal and data to operate, measure, or regulate automated equipment.

Motor Cable

This cable is used in variable-frequency drive motors. It has shielding to block signal interference caused by voltage fluctuations and current spikes.

Welding Cable

This cable withstands abrasion, oil, and the rough conditions found in welding applications.

Flame-Resistant Welding Cable

Approved for flame resistance, this cable meets Mine Safety and Health Administration (MSHA) standards. The insulation resists abrasion and chemicals.
