Cables, connectors, and accessories provide the physical interconnection and supporting hardware required by industrial automation systems. Their architecture varies from passive wiring assemblies to shielded communication cables, fiber-optic links, molded connectors, wiring arms, adapters, plugs, sockets, and equipment-specific accessories. Technical characteristics can include conductor count, cable length, shielding, connector type, pin arrangement, insulation rating, impedance, environmental protection, fiber type, and supported communication standard. Functionally, these components carry power, analog signals, digital signals, network data, or system interconnections between controllers, I/O, field devices, operator interfaces, and other automation equipment. Correct selection depends on the exact system interface, connector geometry, pinout, electrical rating, communication protocol, cable length, and manufacturer part number required by the installed equipment.
