About Wire and Cable

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

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.

Control Cable

Unshielded

Shielded

Control, monitor, and regulate stationary equipment such as sensors and PLCs. You can flex and bend this cable during installation and adjustments, but it isn't made for continuous motion.

Space-Saving Control Cable

Unshielded

Double Shielded

This cable is about two-thirds the diameter of other control cables of the same gauge, so you can fit more cables into the same footprint. The mPPE (modified polyphenylene ether) outer jacket is half the weight of other materials, but still abrasion and tear resistant. This cable controls, monitors, and regulates stationary equipment such as sensors and PLCs. You can flex and bend it during installation and adjustments, but it isn't made for continuous motion.

Double Shielded—With two layers of shielding, this cable offers better protection against electromagnetic interference (EMI) than single-shielded cable. It’s often used near transformers, generators, and heavy-duty motors that may have voltage fluctuations and current spikes that distort signals.

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.

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.

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.

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.
