cable, vdsl, patch

Cable of interface RS-422/485, 2x2x24 AWG SFTP, 120 Ohm, covered with corrugated steel armour, in light-stabilized polyethylene jacket, for operation in the expanded temperature range

1 – Jacket 2 – Corrugated steel armour 3 – Inner jacket 4 – Shield-foil 5 – Shield-braid 6 – Stranded twisted pair

Description

The cable with wave impedance of 120 Ohm designed for the applications like RS-485 and RS-422…common polyester aluminum foil and copper braid shield, covered with the double jacket. The cable is designed for operation in the expanded temperature range, for fixed and non-stationary cabling. Due to the corrugated steel armour protecting from rodents and due to the light-stabilized polyethylene jacket this type of cables is suitable for direct burial application. The cable complies with UL 1581 VW-1, IEC 60332.1.
