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. They 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. These connectors are often used with EtherNet/IP, Profinet, and EtherCAT systems. Since they’re shielded, they block signal interference from nearby devices, maintaining their speed and data integrity. Poles and keyways on the face adhere to standard coding layouts to reduce the chance you’ll mismatch connections.

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

Receptacles thread into a panel or wall, making them best for permanent installations such as control panels or hardwiring into equipment.

Adapters create a transition point between an M12 and RJ45 connection. Use them in panels or walls—your tough threaded connection on one side and your control panel and computer or PLC on the other.

90° elbow connectors run your cord along the side of equipment, so they fit behind machines and in tight spaces.

Connectors with a screw-on wire connection, also known as field wireable connectors, do not require special tools like crimpers or soldering irons to attach to cables. Connectors with a snap-on wire connection pierce the wire’s insulation, which means you don’t need to strip it.

Connectors with polyurethane or TPE insulation resist chemicals, oil, and sunlight for outdoor use. Because they’re flexible, they’re good for jobs with continuous motion, such as robotics.

IP rated connectors keep out dust and can be used in wet areas when mated or capped. IP65 connectors can be lightly rinsed. IP67 connectors can be submerged temporarily. IP69 connectors withstand high-pressure, high temperature washdowns.

Add caps to protect connectors and maintain their IP ratings when not in use.

Food Industry Micro M12 Screw-Together Ethernet Connectors

D Code

FDA compliant to safely touch food and threaded for a tight hold, these connectors 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 connectors.

To reduce the risk of signal loss between equipment, these connectors 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.

M8 Ethernet Connectors

The threaded end of these M8 connectors keeps contaminants out and withstands vibration better than RJ45 ends on traditional Ethernet cords. They are often used with sensors, switches, and I/O modules. To protect against signal interference, these connectors are shielded. Connectors are Power over Ethernet (POE) enabled to carry data and power within one connector.

To view wiring diagrams, select a part number and click Product Detail.

Snap-on wire connections pierce wire insulation, eliminating the need for wire stripping. They maintain a secure hold in high-vibration applications.

Connectors with a polyurethane cable bend easily, so they are ideal for applications that require continuous flexibility such as robotics. They also resist oil.

These connectors are IP rated when mated. IP65 rated connectors protect against dust and low-pressure jets of water. IP67 rated connectors keep out dust and water from temporary submersion.
