Belden 4305ULW Series Multi-Core Microphone & Instrument Cable, 500m Cable Length, 7 Cores - 4305ULW.00500

This multi-core microphone & instrument cable is designed to carry audio signals for professional installations and industrial control environments. It combines stranded conductors and a halogen-free jacket to provide safe signal distribution in enclosed spaces where reduced toxic emission is required. The cable is supplied on a 500 m reel and is intended for low-voltage audio wiring up to 30V in automation, electrical and electronics contexts.

Features and Benefits:

• Seven individually insulated cores for multi-channel routing
• 18 AWG stranded copper conductors for flexible connectivity
• LSZH outer sheath reduces toxic fumes in enclosure incidents
• Unscreened construction simplifies earthing strategies
• Rated for operation between -20°C and 70°C to support varied conditions
• Complies with IEC and EN standards for predictable fire performance

Applications

• Suitable for stage microphone Multicore installations
• Ideal for instrument wiring in live-audio rigs
• Used for low-voltage audio distribution in control rooms
• Can be used for signal cabling in AV integration projects
• Used with Terminal blocks in equipment racks for channel consolidation

What conductor make-up enables flexibility during routing?

Each core comprises seven stranded bare copper elements, which increases bendability compared with solid conductors and eases dressing through trays and conduits.

How does the sheath improve safety in confined spaces?

The jacket material is low smoke zero halogen, formulated to limit corrosive gases and dense smoke when exposed to fire, aiding evacuation and equipment protection.

Which standards confirm its fire and material characteristics?

The cable meets IEC 60754-1/‑2, IEC 61034-2 and EN 50290-2-20 measurements, demonstrating reduced halogen emission and smoke generation under test conditions.

Is this cable suitable for high-temperature installations?

It is specified for continuous use up to 70°C, making it appropriate for typical equipment-room and installation environments but not for elevated thermal exposures beyond that limit.
