Industrial Connectors and Cabling
Industrial connectors of the M8 and M12 standards are round plugs and sockets mainly used in industrial automation, robotics, and control systems. They are most often used for connecting sensors, transmitting data (digital and analog signals), as well as controlling actuators (e.g., actuators). Such connectors (with or without cable) are one of the largest product groups in the Murrelektronik offer.
Among the M8 connectors with a ready-made cable, the manufacturer offers articles with lengths from 1m to 10m, equipped with 3- and 4-pin connectors, supporting maximum voltages up to 24…60V DC and 30…60V AC. The plugs are made in IP65…68 protection class, in straight and angled formats. In the case of M12 models, the voltage ranges are wider, reaching 250V AC/DC, and the cables also support higher currents (up to 12A). This type of cabling can support more lines (2…12 pins), which is why it is often used for industrial communication networks (DeviceNet, Profibus, CANopen), Murrelektronik products are adapted for such applications.

The range of accessories for automation from Murrelektronik also includes connectors and cables in 7/8 inch and M23 formats. It is also worth noting the wide selection of valve connectors (as well as connection cables for pneumatic systems). They have format A, B, or C. These are typical articles used to control the operation of solenoid valves in installations where the medium is air, oil, or water. Due to such applications, they are characterized by high mechanical resistance, as well as IP65/IP67 protection class. In the case of connectors, electrical connection is made using an M12 socket or by introducing the cable into the body through a gland.
Ethernet Switches and Industrial Networks
The use of Ethernet infrastructure is now a commonly used solution in industrial automation systems. Murrelektronik provides switches for such networks within two series: Xelity and Xeterra. In both cases, these are devices for mounting on a DIN rail, the first being typical modules with plastic housings, the second characterized by a shallower profile and metal housing. The latter also have a slightly wider range of supply voltages (9…36V DC and 8…28V AC instead of 9.5…31.5V DC), and better thermal tolerance (-40…70°C instead of -25…60°C).

The manufacturer offers models equipped with 4, 5, 6, 8, or 16 RJ45 ports and screw terminals for power input. These are unmanaged devices, supporting connections up to 100Mb/s. They can successfully serve typical protocols used in industry (PROFINET, EtherCAT, Modbus TCP, and, of course, Ethernet/IP). They are suitable for modernizing or scaling existing control systems (operating in real-time) and can be powered from typical sources available in control cabinets.
Other Network Elements
It is worth noting that Murrelektronik is a company specializing in automation system connectivity, and therefore, in addition to switches, it also provides other products for adapting industrial communication networks. Basic elements here include cables with RJ45 connectors. They are available in lengths from 0.3m to 20m. Their insulation is made of polyurethane or polyvinyl (PUR, PVC), materials resistant to many environmental factors. Most of the cables can operate in places where temperatures range from -25°C to 85°C.
