This Profibus SK range offers FRNC and PUR sheath constructions for fixed indoor and industrial fieldbus routes. The cable is intended for quick connection with compatible plugs and preparation tools. A solid copper pair with foam-skin PE insulation is enclosed by foil screening and a tinned copper braid.

FRNC and PUR sheath versions with separate mechanical data.
AWG 22/1 solid copper conductors and red and green insulation.
150 ± 10 ohms impedance at 3–20 MHz; 8.0 ± 0.4 mm outer diameter.
State FRNC or PUR in the order and use the corresponding bend-radius and temperature data. Match connectors and preparation tools to the SK construction. The FRNC version is listed for indoor fixed installation, while the PUR version serves the industrial heavy-duty option.
Profibus SK Indoor and Outdoor Cable, 150 Ohm, PVC or PE Sheath
Profibus L2 Outdoor and Industry Cable, 150 Ohm, PE or PUR Sheath
Profibus L2 Torsion and Festoon Cables, 150 Ohm, PUR or PVC Sheath
FRNC and PUR are the two sheath materials in the construction table.
The FRNC version lists 18 times the overall diameter; the PUR version lists 15 times.
The FRNC column gives −25°C to +60°C, while the PUR column gives −40°C to +70°C.
A solid AWG 22/1 copper pair is enclosed by aluminium-lined polyester foil and a tinned copper braid.
Specify the sheath version, cable length and compatible connector and preparation-tool system for the SK construction.
