Belden 1803F Z4B, Multi Conductor Snake Cable 4PR 24 AWG PVC
Description
Belden 1803F Z4B is a digital audio snake cable designed for multi-channel interconnects in live events or studio sound. It uses 4-24 AWG tinned copper pairs with Datalene® insulation and individually shielded pairs using bonded Beldfoil. The flexible PVC jacket includes a nylon rip cord to support handling and installation, and it is rated 110 Ohm with low capacitance for AES/EBU applications. CMG and UL1685 FT4 Loading compliance support general-purpose indoor requirements.
Belden 1803F Z4B Key Features
- Uses 4-24 AWG tinned copper pairs for multi-channel digital audio interconnects.
- Features Datalene® insulation with PE - Polyethylene (Foam) construction.
- Includes individually shielded pairs using bonded Beldfoil (Tape, Bi-Laminate (Alum+Poly), 100%) with Indiv. Foil tapes bonded to inner jacket.
- Uses a flexible PVC jacket with a nylon rip cord to support easier handling and installation.
- Provides 110 Ohm nominal characteristic impedence for AES/EBU applications.
- Meets CMG and UL1685 FT4 Loading compliance for indoor installations (Not Riser or Plenum).
Belden 1803F Z4B Applications
- Supports multi-channel interconnects between audio equipment such as microphones, speakers, amplifiers, and mixing consoles.
- Ideal for live events or studio sound setups where organized, multi-channel audio routing is needed.
- Suitable for analog audio signal paths where a multi-pair snake format is preferred.
