About Wire and Cable

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

Control Cable

Unshielded

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.

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.

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.

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.

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.
