About Wire and Cable

Cable

Use this general purpose cable to supply power to equipment.

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.

Stretchable Cable

This cable can be stretched by about 40% and return to its original length, making it useful for applications where cable is in motion. It's often sewn into garments or used with equipment that must be worn.

High-Temperature Cable

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

Corrosion-Resistant Cable

The insulation resists corrosive chemicals and salt water, and the wires in this cable are tin plated for corrosion resistance.

Miniature Cable

Often used in computers, small electronics, and electronic prototyping, this cable is very flexible with small gauge wire to handle tight curves in narrow spaces.

High-Voltage Cable

Often used in mining equipment, submersible pumps, and drilling rigs, this cable withstands 2,000 volts AC/DC.

Direct-Burial Cable

Weather-resistant insulation makes this cable suitable for outdoor use and direct burial without conduit.

Drop-Down Cable

Often used to wire pendant switches, this cable hangs from an overhead connection. Also known as bus drop cable.

Pump Cable

Supply power to submersible pumps in water or oil wells.

Automation Cable

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

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.

High-Voltage Continuous-Flex Flat Cable

A thick outer layer of silicone rubber insulation protects this cable from high voltages while remaining ultra flexible. It stands up to 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.

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.

Thin-Insulation Continuous-Flex Cable

For use in tight spaces, this cable has up to a 40% smaller OD than standard continuous-flex cable. It withstands continuous motion without degrading data or signal transmission.

High-Temperature Continuous-Flex Cable

Bend and flex this silicone-insulated cable in temperatures up to 350° F. It can keep moving in areas twice as hot as most other continuous-flex cables without degrading data or signal transmission.

Data Communication Cable

Use this cable for complex and high-speed data and signal transmission.

Control Cable

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

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.

Thin-Insulation 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.

Variable-Frequency Drive 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.

Building Cable

Riser-Rated Communication
and Security System Cable

This cable is approved for use in vertical shafts and large facilities with multiple levels. It's often used for low-current circuits such as intercoms and security systems.

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.

Duct-Rated Communication
and Security System Cable

Also known as plenum cable, this cable has low-smoke insulation and can be used without conduit in ductwork and above a drop ceiling. Use it in low-current circuits such as intercoms and security systems.

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.

Armored Building Cable

The metal armor on this cable acts as conduit to protect the internal wires. It's often used along the exterior of walls to carry power to outlet boxes. Also known as MC cable.

Building Cable

Rated for in-wall installation, this cable carries power to wall outlets. Also known as branch circuit wire.

Armored Building Cable with Fittings

Also known as fixture whips, this cable has locknuts and fittings attached to the protective metal armor to secure it to a knockout. It's often used to connect light fixtures.

Armored Building Cable with
Uninsulated Ground Wire

This cable has an uninsulated ground wire that touches the protective metal armor so it can be used for bonding and grounding. It's often used along the exterior of walls to carry power to outlet boxes. Also known as AC cable.

Thermostat Cable

Hook up thermostats, air-conditioning units, and other low-voltage equipment.

Power Cords

Connect equipment and devices to a power supply.

Light Duty Power Cords

Designed for indoor applications, these cords are often used to power appliances.

Sure-Grip Power Cords

Also known as hospital-grade cords, these cords have an extra-tight connection to prevent them from detaching. The plug is marked with a green dot.

Coiled Power Cords

These self-coiling cords stretch to full length and then return to their retracted length for tangle-free storage.

International Power Cords

All cords have a country-specific plug to power equipment from international outlets.

GFCI Power Cords

Stop electric shocks before they happen—these cords cut power to equipment when they detect an unsafe current.

Safety Start-Up Power Cords

After a power failure, these cords must be manually reset, preventing unexpected equipment startup.

Turn-Lock Power Cords

Hardwire these cords to equipment.

Shielded Micro M12 Screw-Together Connectors

Block signal interference from nearby devices, such as motors and transmitters, while maintaining a strong, stable connection for M12 threads.

RTD Wire

Make custom RTD probes.
