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). These cords can also power devices as they send data, so you don’t need a separate power cord. But, the device must be Power over Ethernet (PoE) compatible. They’re often used with EtherNet/IP, Profinet, and EtherCAT systems. With TPE insulation, they stand up to bending in robotics applications. It also means they resist abrasion and won’t pit or crack from chemicals, sunlight, and welding runoff.

Thanks to its threads and IP rating, the M12 end is water and dust tight when mated. Poles and keyways on its face adhere to standard coding layouts, which reduces the chance of mismatching connections.

When choosing an Ethernet cord, make sure you match or exceed your network’s ethernet cable category. These cords are backward compatible—for example, a Category 6 cord will work in a Category 5 network, but it’ll only run at the Category 5 speed.
