B7) multi-pair 20-18awg individual foil screened

Alternatives to Belden these multi-pair 20-18awg individual foil screened data cables are designed for instrumentation, computer, audio & monitoring applications. This cable type is recommended for long runs due to reduced losses. The individual foil tape screening provides protection against electrical interference and cross-talk.

These alternatives to Belden 20-18awg pairs IAT screened cables are flexible and come in polyvinylchloride (PVC) or low smoke and fume (LSF) as standard. 

LSF material offers reduced smoke emission / fire propagation compared with standard PVC but may still release hydrogen chloride (HCL) if burnt. There is no standard governing the HCL emissions of LSF cable. LSF should not to be confused with Low Smoke Zero Halogen (LSZH) which guarantees max. 0.5% HCL emissions, for more information please see the in-depth explanation shown on our LSZH Control Flex front page.

These cables are often available in Armoured, Duct Grade or LSZH versions on request, please contact us for more information.
