The Profibus SK range is intended for fixed fieldbus connections using compatible quick-connection plugs and cable preparation tools. PVC and PE sheath options cover indoor and outdoor routes. Solid copper conductors, foam-skin PE insulation, foil screening and a tinned copper braid form the signal cable construction.
