Shielded Ethernet Cords

The shielding blocks signal interference from nearby equipment and devices.

Ethernet Cords

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

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).

Ethernet Cords with M12 Connectors

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

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.

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.

Ethernet Cords with M8 and RJ45 Connectors

Send high-speed data between sensors, switches, or I/O modules with an M8 connection and programmable logic controllers (PLCs) and computers with a traditional RJ45 connection.

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.

Panel-Mount Ethernet Cords

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

Ethernet Cords with M8 Connectors

Unlike the RJ45 ends on traditional Ethernet cords, the threaded M8 ends on these cords keep contaminants out and resist coming loose from vibration.

Single Pair Ethernet Cords

These cords contain a single pair of twisted wires, making them lighter and more flexible than other Ethernet cords. They’re good for transportation, robotics, and automation applications.

ix Industrial Cords

Securely connect equipment in data or signal applications. These cords have A- or B-coded plugs to meet the needs of your device.

M8 Ethernet Connectors

A threaded M8 end on these connectors keeps contaminants out and withstands vibration better than RJ45 ends on traditional Ethernet cords.

Ethernet Switches

DIN-Rail Mount Ethernet Switches

Mount these Ethernet switches to DIN rail to bring connections closer to where you need them.

ix Industrial Ethernet Switches

Link industrial equipment with multiple computers to expand your data network.

Power Over Ethernet Injectors

With a single cord, send data and electricity to Power over Ethernet (PoE) compatible devices. These injectors are commonly used to run devices such as routers and wireless access points in areas where no power outlet is nearby.
