About Wire and Cable

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

Vehicle Cable

Also known as GPT cable, this cable is often used in low-voltage applications such as battery and vehicle wiring and radios. It has one red wire and one black wire to easily identify polarity. The wires can be pulled apart for installation.

Continuous-Flex Control Cable


Unshielded	Shielded

Even after millions of flex cycles, this cable transmits reliable signals. Its finely stranded conductors are twisted together like a rope to resist wear from constant bending. Use it in moving equipment such as cable carriers.

Unshielded—Choose unshielded wires when electromagnetic interference (EMI) isn't a concern. Equipment such as motors and pumps may have voltage fluctuations and current spikes that distort signals.

Shielded—A single layer of shielding protects sensitive electronics and control systems by blocking electromagnetic interference (EMI). Otherwise, equipment such as motors and pumps could distort signals.

Industrial CAN-Bus Cable

Connect devices such as sensors, PLCs, and actuators to a CAN-Bus network.

Use this continuous-flex cable in automated applications that require continuous motion, such as robotics. This double shielded cable has a layer of braid and foil shielding for better protection against signal interference than foil alone. Use it in environments with high signal distortion, such as near transformers, generators, and heavy duty motors.

This flame-rated cable meets requirements for preventing the spread of flames based on a timed test. VW-1 cable is suspended vertically during testing.

PVC Outer Jacket—Choose cable with PVC outer jacket for general purpose indoor applications. Its protective layer resists abrasion, though it contains halogen. It’s also less flexible than cable with TPE jacket.

TPE Outer Jacket—Cable with TPE outer jacket has a protective layer that is more flexible and resists abrasion better than other materials. It also stands up to extreme temperatures and chemicals, making it good for use in harsh outdoor environments.

High-Temperature Power Cable

Shielded

When others can't take the heat, this cable delivers power in ovens, furnaces, steel mills, and foundries. The PTFE jacket won't degrade and weaken as temperatures rise. It also resists abrasion, chemicals, oil, and moisture.

Shielded—Shielding stops these cables from acting as antennas that emit electromagnetic interference, which could disrupt nearby equipment such as control or data cables.

Thermostat Cable

Hook up thermostats, air-conditioning units, and other low-voltage equipment. This cable is designated CL2 so it has flame-resistant insulation. The wires are solid so it stays in the shape you bend it.

No-Conduit-Required Continuous-Flex Control Cable

Unshielded

Shielded

Eliminate the need for conduit and cable splices. Made to TC-ER (Tray Cable, Exposed Run) standards, this cable resists impact and crushing force. You can run a single length from stationary equipment to and through moving equipment, such as cable carriers. Support it every six feet to prevent sagging. Even after millions of flex cycles, this cable transmits reliable signals. Its finely stranded conductors are twisted together like a rope, strengthening the cable and preventing fatigue from constant bending.

Space-Saving Continuous-Flex Control Cable

Cut congestion in crowded cable carriers that are always moving. This cable is one-third the diameter of other control cables of the same gauge, letting you fit more into the same footprint. Its slim profile comes from mPPE (modified polyphenylene ether) insulation, which is nearly half the weight of other insulation materials. Its finely stranded conductors are twisted together like a rope to resist wear from constant bending. The rugged jacket protects the cable from wear and tear and exposure to chemicals, oil, and moisture. Altogether, this cable endures millions of flex cycles while maintaining reliable signals.

Twisted-Pair Continuous-Flex Control Cable

Prevent mixed messages in control systems such as sensors and PLCs. The twisted-pair wires in this cable prevent internal and external signal interference, even in electrically noisy areas. Designed for the demands of continuous motion, this cable transmits signals for millions of flex cycles. Its finely stranded conductors are twisted together like a rope to resist wear from constant bending.

High-Voltage Continuous-Flex Flat Power Cable

For high-voltage systems with constant motion, this cable flexes without breaking. Its thick silicone rubber jacket insulates against high voltage and resists chemicals, oil, moisture, and UV rays. The jacket also has a low-smoke, zero-halogen (LSZH) design to prevent toxic emissions if there’s a fire.
