LSZH Flame Retardant RS 485 Databus Cables

LSZH Flame Retardant RS 485 Databus Cables (Multipair)

APPLICATION

The cables are designed for RS 485 data connections where continued functionality is required during a fire situation. This cable combines low capacitance insulation with one of the highest levels of screening to provide high speed, interference free, data transmission where continued functionality is required during a fire situation.

STANDARDS

Basic design adapted to EIA/TIA 485

FIRE PERFORMANCE

Flame Retardance (Single Vertical Wire Test) IEC 60332-1-2; EN 60332-1-2
Reduced Fire Propagation (Vertically-mounted bundled wires & cable test) IEC 60332-3-24; EN 60332-3-24
Halogen Free IEC 60754-1; EN 50267-2-1
No Corrosive Gas Emission IEC 60754-2; EN 50267-2-2
minimum Smoke Emission IEC 61034-2; EN 61034-2

CABLE CONSTRUCTION

MULTIPAIR RS 485 OVERALL SCREENED DATABUS CABLE
Conductors: Tinned copper wire, stranded according to IEC 60228 class 2 or class 5.
