About Wire and Cable

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

Electrical Wiring and Connecting

Ethernet Cable

Send data between computers, printers, servers, and switches.

Continuous-Flex Ethernet Cable

Often used in automated applications that require continuous motion, this cable sends data between computers, servers, and switches without degrading signal transmission.

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.

Oil-Resistant Ethernet Cable

From mines and factories to robotics, this rugged Ethernet cable sends data between sensors and switches in the grimiest places.

Duct-Rated Oil-Resistant 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. It has an oil-resistant insulation to protect wires as the cable moves from duct to equipment or machinery.

USB Adapter Cords

Adapt your USB port to connect to a variety of other devices.

Ethernet Cords

Use these unshielded cords where signal interference is not a concern.

Shielded Ethernet Cords

The shielding blocks signal interference from nearby equipment and devices.

Ethernet Cords with M12 and RJ45 Connectors

To send high-speed data in tough, rugged environments, these cords have an M12 connector on one end that threads onto switches, sensors, and other devices prone to vibration. The other end has a traditional RJ45 plug that connects to Ethernet equipment, such as computers, IO modules, and programmable logic controllers (PLCs).

Continuous-Flex Ethernet Cords

Often used in automated applications such as robotics, these cords withstand continuous motion without degrading data transmission. They have an RJ45 plug on each end.

Panel-Mount Ethernet Cords

Use these unshielded cords where signal interference is not a concern.

Shielded Panel-Mount Ethernet Cords

Often used in labs, storage facilities, and offices, the shielding blocks low to moderate signal interference from nearby equipment and devices. These cords have a flange on the socket end to mount them in a panel cutout.

Duct-Rated Ethernet Cords

Also known as plenum-rated cords, these CMP ethernet cords have flame-resistant, low-smoke insulation and can be used without conduit in duct work and above a drop ceiling.

Ethernet Cords with Adjustable-Angle Connectors

The plugs on these cords pivot up to 90° in each direction to fit Ethernet jacks at awkward angles or in tight spots, such as behind equipment or in enclosures.

Ethernet Cords with M12 Connectors

The M12 threaded connectors on these cords are more vibration resistant than RJ45 connectors.

Ethernet Cord Reels

Keep an ethernet cord on hand but out of the way.

Unshielded Easy-Install Crimp-On Data Connectors

Pull wires all the way through the connector face, and then use the crimper to cut and crimp wires in one step.

Shielded Easy-Install Crimp-On Data Connectors

Protect sensitive equipment from electromagnetic interference.

Micro M12 Screw-Together Ethernet Connectors

Unlike traditional RJ45 connectors found in data centers, these connectors stand up to rugged industrial environments since they tightly thread to devices with M12 connections, sealing out contaminants and resisting shaking loose from vibration. Use them to transfer high-speed data between sensors, switches, computers, IO modules, programmable logic controllers (PLCs), and other equipment.
