The Profibus PA Long Distance construction provides a stranded-conductor option for process-automation fieldbus wiring. It combines bare copper AWG 16/7 conductors, PE insulation, foil and braid screens, and a PVC sheath. The product data specify attenuation of no more than 2.7 dB/km at 39 kHz for use in segment design.

AWG 16/7 stranded copper conductor construction.
Aluminium-lined foil and tinned copper braid screening.
100 ± 20 ohms impedance at 31.25 kHz and 300V working voltage.
Calculate the PA segment using its cable length, attenuation, device loading and power-supply arrangement. Specify the required route and terminations with the order. For hazardous-area use, the cable selection forms part of the complete system protection concept and equipment installation requirements.

Profibus L2 Direct Burial Cable, 150 Ohm, PVC Inner and PE Outer Sheath
Profibus L2 7-Wire Stranded Cable, 150 Ohm, PVC Sheath for Mobile Use
It has stranded AWG 16/7 copper conductors, a 9.5 ± 0.5 mm outer diameter and a listed attenuation limit of 2.7 dB/km at 39 kHz.
The cable uses PE conductor insulation and a PVC outer sheath.
Aluminium-lined polyester foil and an overall tinned copper braid surround the signal pair.
The operating temperature range is −40°C to +70°C.
The minimum listed radius for laying is 7.5 times the overall cable diameter.
