All systems are assemblies of devices that, when working together, are wired or wirelessly connected to each other. Various types of interfaces, connectors, couplings, etc. are used to connect two or more components, devices, cables or wires physically. For two devices or more devices to work together, their interfaces should be compatible with each other. Among the connection products, we can distinguish between cable splice closures, plug-in connectors, terminal blocks, rail connectors, and more.
