Description
- Unarmoured (Type 1)
- Individual & Overall Screen (IOS)
- Lead free
- Aliphatic and aromatic hydrocarbons resistant
Standards
International : IEC 60331; IEC 60332-3-22 Cat.ADescription
Applications
These instrumentation and communication cable are used to transmit analogue or digital signals in measurement and process control in moist areas and where aliphatic and aromatic hydrocarbons may be present. The individual screening of each pair limits the consequence of crosstalk. Hypron® offers an alternative to conventional lead covered cable and is an environmental friendly solution. They maintain circuit integrity when exposed to fire.
