Belden 7704NH Series Twisted Pair Cable, 2 Pairs, 22 AWG, 500 m Low Smoke Zero Halogen

This twisted & multipair industrial cable is designed for signal and control wiring in industrial environments. It combines a two-pair twisted configuration with solid bare copper conductors and a low-smoke zero-halogen outer sheath to maintain circuit integrity and reduce hazardous emissions during fire conditions. The cable is suitable for fixed installation where moderate temperature ranges and a 300V rating are required.

• Solid bare copper conductors enabling consistent conductivity
• 22AWG cross section supporting Compact routing and terminations
• LSZH jacket reducing toxic gases and dense smoke
• Rated for continuous operation up to 80°C
• Withstands storage and use down to -15°C
• Meets IEC 60332-1-2 and IEC 60332-3-24 fire performance

• Suitable for industrial automation control loops
• Ideal for panel wiring in electrical enclosures
• Used for signal transmission in machinery installations
• Can be used for connections within instrumentation racks

It contains two individually twisted pairs of solid bare copper conductors with a polymeric LSZH outer sheath designed to limit halogen emissions.

The insulation system and conductor construction are specified for a maximum working voltage of 300V.

The sheath and materials conform to IEC 60332-1-2 and IEC 60332-3-24, indicating limited flame propagation and reduced smoke/halogen output under specified test conditions.

The cable has an outside diameter of 6.5mm suitable for tight bundle routing and tray-filling calculations.

It is provided on 500m lengths allowing longer continuous runs without intermediate joins.
