B5) single or multi-pair 24awg overall foil RS232

Single or multi-pair 24awg overall foil RS232 Belden alternative screened data cable types are designed for point of sale, control systems, computer systems and RS232 applications. The overall foil tape screening provides protection against electrical interference. 

These alternatives to Belden 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.
