These connectors run the automated world, from robot arms and photoelectric sensors to PLCs, IO-Link devices, and Ethernet switches. The original metric circular connector, they continue to be the standard today. They screw together tightly to protect against contaminants and hold firm against high vibration. Each one has a coding that indicates a unique keyway, preventing mismated connection errors before they happen. The coding also tells you whether a connector can send power, control, or data. Some can send a combination of the three, reducing the need for multiple connectors.

Use these compact connectors in spaces where M12 connectors won't fit. They're often used in crowded, high-vibration areas such as robot arms and IO-Link devices with many connections. They also fit on miniature proximity and photoelectric sensors.

Use these connectors and cords to make Ethernet connections. Caps (sold separately) protect sockets and maintain the IP rating when not in use.

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.

FDA compliant to safely touch food and threaded for a tight hold, these cords won’t vibrate loose as they send high-speed data to sensors and other automated devices in food, beverage, and pharmaceutical plants. They stand up to brief submersion as well as high-heat washdowns and harsh cleaners common to food lines, thanks to their IP ratings, TPE insulation, and stainless steel and polypropylene housing. Their insulation also means they’re flexible and won’t break down from abrasion or UV exposure. Overall, they’re more rugged than traditional RJ45 cords.

To reduce the risk of signal loss between equipment, these cords block signal interference from nearby devices. Poles and keyways on their face adhere to standard coding layouts, keeping you from mis-mating connections. D coded, these connectors are often used within Ethernet/IP, Profinet, and EtherCat systems. They can also power devices as they send data, so you don’t need a separate power cord. But, your device must be Power over Ethernet (PoE) compatible.
