APPLICATIONS

BUS O2YS(St)CY 1x2x1,0/2,6 mm is cable intended for industrial PROFIBUS PA control systems.

For proper transmission of digital and analogue signals the cable is protected by a specially designed and highly effective collective shield against external electromagnetic interferences.

Cable outer sheath is oil-resistant.

The cables are suitable for fixed indoor installations.

CONSTRUCTION

- annealed copper single wire round conductors of diameter 1.0 mm,

- foam-skin polyethylene insulation - identification colour code: blue and orange,

- insulated conductors twisted into a pair,

- collective shield incorporating an aluminium-polyester tape under a tinned copper wire braid,

- oil resistant PVC sheath, blue RAL 5015, other colours also available.

AVAILABLE UPON REQUEST

BUS O2YS(St)CYv 1x2x1,0/2,6 mm - cable of enhanced and oil resistant PVC sheath, suitable for outdoor installations and direct earth burial.

BUS O2YS(St)CY2Y 1x2x1,0/2,6 mm - cable with additional polyethylene (PE) sheath, suitable for outdoor installations and direct earth burial.
