Belden YZ65749 is a precision-engineered, shielded 1-pair communication cable designed for high-performance RS-485 and Modbus industrial protocols. Utilizing a metric-sized 0.5mm² (approx. 20 AWG) conductor cross-section, it is specifically optimized for applications requiring lower DC resistance and enhanced signal reliability over longer distance runs compared to standard 24 AWG cables.

Product Description

YZ65749 is built for demanding automation and instrumentation environments where signal integrity must be maintained despite the presence of electrical noise. The use of 0.5mm² conductors makes this cable a robust choice for industrial systems where minimizing voltage drop is critical for consistent device performance.

Key Technical Specifications
Conductor Construction: 1 pair of 0.5mm² stranded tinned copper conductors. The larger cross-sectional area compared to 24 AWG cables allows for better current-carrying capacity and lower signal attenuation.

Dielectric/Insulation: High-grade Polyethylene (PE) or similar low-capacitance insulation, ensuring the cable maintains the required 120-Ohm characteristic impedance essential for RS-485 termination.

Shielding Architecture:

Foil Shield: 100% coverage aluminum/polyester foil provides excellent shielding against high-frequency electromagnetic interference (EMI).

Braid Shield: An overall tinned copper braid provides high structural strength and protects against low-frequency interference.

Drain Wire: Includes an integrated drain wire to facilitate proper equipment grounding and shield termination.

Outer Jacket: A rugged, flame-retardant PVC outer jacket providing mechanical protection against abrasion and environmental stressors commonly found in factory settings.

Primary Applications
Industrial Modbus Networks: Highly reliable for interconnecting industrial controllers, drives, and sensors in complex automation loops.

Long-Distance Data Transmission: The 0.5mm² conductor gauge makes this an ideal candidate for long-distance RS-485 runs where 24 AWG cables might suffer from excessive signal loss.

Process Instrumentation: Used in distributed control systems (DCS) and SCADA networks where stable communication is vital for plant operation and safety.
