B12) multi-pair 24awg ind+overall foil+braid RS422

Alternatives to Belden these multi-pair 24awg ind+overall foil+braid RS422 flexible data cables have individual & collective aluminium tape screens & tinned copper wire braid. This cable type is designed for RS422 and similar applications where high speed data transmissions are required. The three layers of screening, first individual foil tapes then overall foil tape then a tinned copper wire braid ensures excellent protection against electrical interference.

These equivalents 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.
