LI2Y(St)CY Signal Cables Selection Guide: Technical Criteria & Application Standards
LI2Y(St)CY Signal Cables selection guide: technical parameters, mounting and compliance standards, and Birtaş Kablo, Reçber Kablo comparison.
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. The LI2Y(St)CY Signal Cables category on Welibaba includes 21 active models from leading manufacturers such as Birtaş Kablo, Reçber Kablo.
Key Technical Parameters for Selecting LI2Y(St)CY Signal Cables
To specify the right LI2Y(St)CY Signal Cables model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Core Cross-Section | 1x2x0, 22 mm², 1x2x0, 50 mm² | Verify against project schedule and load calculation |
| Cable Type | LI2Y, LI2Y(St)CY PIMF | Verify against project schedule and load calculation |
| Copper Weight | 27 kg/km, 32 kg/km, 39 kg/km, 40 kg/km | Verify against project schedule and load calculation |
| Stranding | İki damar bir çift olarak bükülür; çiftler (PIMF) uygun adımda katlar halinde bükülür | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Signal Cables.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as LIYY Signal Cables, LIYCY Signal Cables, LIHH Signal Cables.
