LAPP LI2YCY-PiMF Low Capacitance Shielded Data Cable 30MHz PE Insulation

1. Product Overview
UNITRONIC® LI2YCY-PiMF is a shielded cable designed by LAPP in Germany for low-frequency, high-fidelity data transmission. Each pair of cores utilizes a separate shield (Pair in Metal Foil, PiMF) consisting of aluminum foil and a drain wire, plus an overall tinned copper braided shield. This effectively suppresses near-end crosstalk (NEXT) and external electromagnetic interference (EMI), ensuring signal integrity. Low-capacitance PE insulation enables longer transmission distances and minimizes signal attenuation, making it ideal for environments with high electromagnetic interference, such as industrial plants, building automation, weighing systems, and inverter signal links.

2. Key Features and Benefits
• Double shielding: PiMF pair shield + tinned copper braid, shielding effectiveness ≥ 80 dB (30 MHz)
• Low capacitance: typically 30–50 pF/m, supporting high-speed, long-distance transmission
• Flame-retardant PVC outer jacket, meets IEC 60332-1-2 single-wire vertical flame test
• Low-temperature flexibility: no brittle cracking at -40°C, suitable for cold storage and outdoor applications
• Oil and chemical resistance: meets DIN EN 50290-2-22 oil resistance class TM54
• Environmentally friendly: Complies with RoHS/REACH and CE low voltage directives
• Color: Pebble gray RAL 7032 for easy field identification

3. Typical Applications
• Industrial Ethernet, PROFIBUS, RS-422/RS-485 fieldbuses
• Signal connections for PLCs, DCSs, inverters, and servo drives
• Precision weighing, medical analysis instruments, laboratory data acquisition
• Building automation, security CCTV control circuits
• Robotics, AGV drag chains or flexible installation (mainly fixed wiring)
