About Wire and Cable

Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

Multipurpose 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.

Low-Voltage Cable

Rated to 12 volts DC, this cable is often used in low-voltage applications such as battery and vehicle wiring and radios. Also known as GPT cable.

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.

Abrasion-Resistant Cable

A thick rubber insulation resists cuts and abrasion, so this cable can be pulled over rough surfaces without damaging the wires inside.

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.

Appliance Cable

Also known as zip cord, this cable is often used in lamps, heat guns, and other small appliances.

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

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.

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.

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.

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.

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.

Building Cable

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
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.

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.

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.

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.

Thermostat Cable

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

Armored Fire Alarm Cable

Prevent damage to wires for fire alarm systems, smoke detectors, and other critical circuits with this armored cable.

Riser-Rated Fire Alarm Cable

This cable is approved for use in vertical shafts and large facilities with mulitple levels for critical circuits such as fire alarms and smoke detectors.

Duct-Rated Fire Alarm 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 in critical circuits such as fire alarms and smoke detectors.

Access Control Cable

Wire multiple components in your security system using a single cable.

Control Cable

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

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.

Water-Block Control Cable

Keep water from damaging wires—this cable has a layer of absorbent material that traps moisture before it reaches the internal wires. It sends signal and data to operate, measure, or regulate automated equipment.

Data, Audio, and Video Cable

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.

Industrial Communication-Standard Cable

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

Audio Cable

Hook up speakers, intercoms, and other low-current devices to a building's communication wiring.

Cords

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.

Equipment-Cooling Fan Power Cords

Plug these cords into fans that have quick-disconnect terminals.

Profibus Cords

Often used in assembly line networks and Fieldbus connections, these cords have B-coded M12 connections.

Temperature and Humidity Monitoring

RTD Wire

Make custom RTD probes.

Thermocouple Wire

Make your own thermocouples.

Thermocouple Extension Wire

Designed to carry thermocouple signals over longer distances than standard thermocouple wire, this extension wire lengthens existing thermocouple connections.

Grommets for Flexible Metal Conduit and Armored Cable

Grommets for Flexible Metal
Conduit and Armored Cable

Also known as antishort bushings, these grommets slide into the ends of conduit and armored cable to protect wire and cable from sharp edges.
