Telecommunication cable Madex YTKSY 4×2×0.5 mm², twisted pairs for signal and voice transmission

Madex YTKSY 4×2×0.5 mm² telecommunication cable is designed for voice and low-frequency signal transmission in indoor telephony and data-signal installations. The cable contains four insulated pairs, each conductor having a cross-section of 0.5 mm², arranged as twisted pairs to reduce crosstalk and external interference. The construction is intended for fixed indoor wiring, patching and connecting terminal equipment in buildings and communication cabinets where low-voltage analogue or digital signals are required.

Advantages

The twisted-pair design provides improved noise immunity for voice and low-frequency signals. Four pairs in a single sheath allow multiple lines or channels to be run without separate conduits, simplifying installation. Insulated conductors with consistent 0.5 mm² cross-section ensure predictable electrical characteristics and reliable contact with standard telecommunication connectors. The cable’s indoor-rated construction supports installation in communication cabinets, wall ducts and patch panels.

Suitable for

• Indoor telephony wiring and multi-line telephone systems
• Low-frequency analogue signal transmission and control circuits
• Connecting terminal equipment, patch panels and distribution frames
• Short-run horizontal cabling inside buildings and communication racks

Key specifications

• Conductor configuration: 4 insulated pairs (twisted pairs)
• Conductor cross-section: 0.5 mm² per conductor
• Designed signal type: voice and low-frequency data signals
• Installation environment: indoor use, building wiring and communication cabinets
• Pair arrangement: twisted to reduce interference and crosstalk

How to use

Strip outer sheath carefully to expose the four twisted pairs without nicking the conductors. Separate and untwist pairs only as much as needed to terminate on standard telecommunication connectors or punch-down blocks. Use compatible terminals or RJ-type connectors specified for 0.5 mm² conductors and ensure secure, corrosion-free contacts. Route the cable through ducts or cable trays avoiding proximity to high-voltage power lines and major sources of electromagnetic interference. Follow local building and wiring codes when installing inside walls or cabinets.

Usage recommendations

For stable voice and control signals, minimize untwisting length at termination points, maintain recommended bend radius, and avoid bundling tightly with power cables. Test lines after installation with appropriate continuity and signal-quality tools to confirm correct connections and acceptable interference levels.
