Alternatives to Belden these single or multi-pair 24awg overall foil+braid RS485 low capacitance data cables are designed to provide high speed data transmission and are suitable for RS485 applications. The two layers of screening, first an overall foil tape then a tinned copper wire braid ensures excellent protection against electrical interference.
These alternatives to Belden cable types 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.
