Aluminium-lined foil and overall tinned copper braid screening.
300V working voltage and 7.6 ± 0.2 mm outer diameter.
Choose the sheath colour and termination arrangement to match the project. Include cable length, device loading and power-supply arrangement in the PA segment design. For hazardous-area circuits, select the cable as part of the complete protection concept and the equipment installation requirements.
Profibus PA Long Distance Cable, 100 Ohm, Stranded Copper, PVC Sheath
Profibus L2 Indoor Cable, 150 Ohm, Foil and Braid Screened, PVC
Profibus SK Indoor and Outdoor Cable, 150 Ohm, PVC or PE Sheath
The characteristic impedance is 100 ± 20 ohms at 31.25 kHz.
The cable uses bare copper AWG 18/1 solid conductors.
PE insulation surrounds the conductors, with PVC as the outer sheath material.
Aluminium-lined polyester foil and an overall tinned copper braid surround the pair.
The outer diameter is 7.6 ± 0.2 mm. The listed minimum laying radius is 18 times the overall diameter.
