EN 50288-7 Silicone IOS Armoured 5x2x0,5

Applications

These Instrumentation and communication are used to transmit analogue or digital signals in measurement and process control. They are well adapted to underground use in industrial applications where chemical and mechanical protections are needed (refinery areas, chemical plant...). The individual screening of each pair limits the consequence of crosstalk. They maintain circuit integrity when exposed to fire.
