UNITRONIC® Li2YCY PiMF
Shielded data cable with PE core insulation and statically shielded core pairs
UNITRONIC® Li2YCY PiMF – shielded PVC data cable with individually shielded pairs for areas with a high level of electromagnetic interference
Metal foil shielded pairs (PIMF)
Benefits
- Data cable with low capacitance, pair screening and copper braiding
- Particularly suitable for wiring data systems and controls in large-scale technical facilities
- 7-wire braided conductor can be used for Maxi TERMI-POINT® wiring
- Individually shielded core pairs and the overall shielding minimise electrical interference
- Decoupling of circuits by means of
twisted-pair (TP) design (crosstalk effects)
Application range
- For increased requirements for near-end cross-talk attenuation and in the case of high electrical interference in the circuits
- Suitable for the transmission in case of varying signal levels in the circuits and with weak, sensitive signals
- Versatile applications for computer systems, electronic control and regulating devices, office machines, scales etc.
- For measurement value transmission and serial 2-wire interfaces
- Intended for limited flexible use, and for fixed installation in dry or damp interiors
Product features
- Flame-retardant according to IEC 60332-1-2
Design
- 7-wire or fine-wire (from 1 mm²) strands made of bare copper wires
