Application fit

Is Li2YCY (TP) right for your machine?

Li2YCY (TP) replaces PVC core insulation with non-polar polyethylene (`2Y` = 2YI1), cutting mutual capacitance by more than half (~50 nF/km vs ~120 nF/km in LiYCY) to preserve square-wave edge integrity over long EIA RS-485 / RS-422 and SSI encoder runs.

Fixed installation

Suitable

Long-distance RS-485 / RS-422 multi-drop networks, SSI absolute encoders, Modbus RTU and high-speed digital telemetry.

VFD inverter to AC motor screened feeder

Suitable

Dual Al/PET foil + ≥80 % tinned-copper braid screen provides wide-band RF and low-frequency interference rejection.

Trailing & towing

FAQ

Questions engineers ask first

What does '2Y' mean in Li2YCY (TP)?

In DIN VDE 0207 / VDE 0812 nomenclature, '2Y' designates thermoplastic polyethylene (PE, Type 2YI1) core insulation. Because polyethylene has a relative permittivity of ~2.3 compared with ~4.5–6.0 for PVC ('Y'), it lowers the mutual core-to-core capacitance from ~120 nF/km down to ~45–55 nF/km and raises insulation resistance above 5 GΩ·km.

Why is low capacitance critical for RS-485, RS-422 and SSI encoder cables?

High cable capacitance rounds off fast digital clock and data edges, causing inter-symbol interference and reflections over long runs. With ~50 nF/km capacitance and a 100–120 Ω characteristic impedance, Li2YCY (TP) supports RS-485 / RS-422 bus lengths up to 1200 m at standard baud rates.

What is the difference between Li2YCY (TP) and Li2YCYv (TP)?

Standard Li2YCY (TP) has a pebble-grey (RAL 7032) PVC outer sheath for indoor racks, cable trays and machine tools. Li2YCYv (TP) adds a reinforced ('v' = verstärkt) black (RAL 9005) UV-stabilised PVC outer sheath for heavy mechanical duty and sheltered outdoor cable ducts.

Can Li2YCY (TP) be terminated in standard D-Sub and M12 connectors?

Yes. The 0.22 mm², 0.25 mm² and 0.34 mm² conductor sizes fit standard crimp and solder pins in D-Sub (9/15/25-pin) and M12 industrial circular connectors.
