About Wire and Cable

Wire

Also known as hook-up wire, this wire is primarily used for wiring electrical panels, lighting, and plant floor equipment.

Mil. Spec. Wire

This wire meets stringent military specifications for material quality.

Tangle-Free Wire

Eliminate tangles—the slippery insulation on this wire won't catch on itself, other wires, or on rough surfaces.

Building Wire

Install this wire in conduit and cable trays throughout commercial and industrial buildings. It's also known as branch circuit wire.

Long-Life Continuous-Flex Wire

The thin strands in this wire have better fatigue resistance under repeated flexing than the strands in standard continuous-flex wire, so it will last longer.

Circuit Board Wire

Make connections in circuit boards with these short lengths of terminated wire.

Cable

Use this general purpose cable to supply power to equipment.

Drop-Down Cable

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

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.

Space-Saver 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.

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.

Ribbon Cable

Often used in electronic prototyping or in the interior of computers, this flat cable is ultra flexible with small-gauge wires so it fits in tight spaces.

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.

Building Cable

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

Continuous-Flex Data Communication Cable

Often used to send signal and data to order pickers and cranes, this cable withstands continuous motion applications without degrading data or signal transmission.

Data Communication Cable

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

Twisted-Pair Data Communication Cable

This cable has twisted pairs of wires that cancel signal interference from multiple transmission lines. Use it for complex and high-speed data and signal transmission.

Industrial Communication-Standard Cable

Connect devices such as sensors, programmable logic controllers, and actuators to an automated network.

Ethernet Cable

Send data between computers, servers, and switches in an office or workstation.

Duct-Rated Ethernet 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 to send data between computers, servers, and switches.

Telephone Cable

Connect telephones and telephone blocks to a wall jack.
