LI2Y(St)CY Signal Cables

The LI2Y(St)CY PIMF cable is a data transmission cable with polyethylene (PE) insulated cores arranged in twisted pairs, each pair individually foil shielded, with a common copper braid shield and a PVC outer sheath over them. Thanks to the low capacitance of PE insulation, it is used to carry data over longer distances on serial interfaces such as RS-232 and RS-422, and on measurement data and device-to-device communication lines. In the category, Birtaş Kablo and Reçber Kablo products are sold by the meter in pair counts and cross-sections such as 1x2x0.50 mm², 2x2x0.75 mm², 3x2x0.22 mm² and 4x2x0.50+0.22 mm². Choose the number of pairs according to the needs of the communication interface, the cross-section according to line length, and the capacitance and characteristic impedance values according to the device manufacturer's cable recommendation. In the notation, 2x2x0.50 mm² means two pairs, that is, four cores; the abbreviation PIMF indicates that the pairs are individually shielded in metal foil. Although LI2Y(St)CY has low capacitance, it is not considered suitable for every field network: in networks such as PROFIBUS, where the cable impedance is defined by the protocol, it is not a substitute for the bus cable specific to that protocol.

How to choose LI2Y(St)CY Signal Cables

The LI2Y(St)CY PIMF cable is a data transmission cable with polyethylene (PE) insulated cores arranged in twisted pairs, each pair individually foil shielded, with a common copper braid shield and a PVC outer sheath over them. Thanks to the low capacitance of PE insulation, it is used to carry data over longer distances on serial interfaces such as RS-232 and RS-422, and on measurement data and device-to-device communication lines.

  • Clarify the circuit duty first: power distribution, control, fire safety, Ethernet or analog signal.
  • Compare conductor cross-section, core count, insulation and shielding against the installation route.
  • Switch to the proper cable family early when flex duty, oil resistance, halogen-free jacket or fire integrity is required.
