What are Fieldbus Connectors?
Meet the Connector: Fieldbus Connectors
Fieldbus is an industrial network used to connect instruments in manufacturing environments. Multiple types of fieldbus networks exist to serve a variety of applications, including EtherNet/IP, PROFINET, PROFIBUS, and DeviceNet. Fieldbus connectors simplify the process of linking fieldbus equipment to network segments. They eliminate the need for junction boxes using conventional terminal blocks. Coupling devices provide a convenient way to form highly reliable connections between field instruments and the trunk cable, but many of them are equipped with features such as short circuit protection and spur status LED indication.
Many different types of connectors are used in fieldbus networks, including D-Sub, metric circular connectors (e.g., M12, M15, M17), RJ45, and Ethernet.
Fieldbus connectors are also known as fieldbus couplers, fieldbus distributors, field device connectors, or bricks.
Cables for the fieldbus connectors require plugs that match the coupling sockets. Since the plugs are bulky, the cable must either be pulled through an oversized electrical conduit to allow for the width of the plug, or the plug must be installed after the cable is pulled through the conduit.
Fieldbus connectors are used in industrial settings, specifically factory environments. They are designed to withstand the environmental demands associated with factories and, depending on the specific application, they may be shielded and rated for ingress protection (e.g., IP67 or IP69K)
