Electrical connectors and wiring devices facilitate the transmission of electrical and data/signal connections. Wire connectors, terminals, and terminal blocks join conductors and circuit points to transfer connections. Plugs, receptacles, and wiring devices make and maintain electrical connections. Circular connectors have threaded locks that are plug-and-play and suitable for industrial and automated applications. Rectangular connectors have modular frames that accommodate different types of connector modules in one body. Data and network interface connectors join cables, devices, and machinery to transfer data, signals, and power.
