YJ70124 2 PAIR RS485 MODBUS UNARMORED

Belden YJ70124 is a high-performance, two-pair shielded twisted pair cable designed for reliable RS-485 and Modbus serial communication. Engineered for industrial environments, it features 24 AWG stranded tinned copper conductors, low-capacitance insulation, and a dual-layer shielding system to ensure maximum signal integrity and noise immunity for multi-node network configurations.

Product Description

YJ70124 is a professional-grade data cable specifically designed to manage two independent signal channels in a single, compact, and shielded assembly. Its construction minimizes crosstalk between pairs while providing superior protection against electromagnetic interference (EMI) and radio frequency interference (RFI) common in industrial settings.

Key Technical Specifications
Conductor Construction: Two pairs of 24 AWG (7x32) stranded tinned copper conductors. The stranded wire provides the necessary flexibility for installation in cable trays, conduit, or complex control cabinets.

Dielectric/Insulation: High-grade Polyethylene (PE) insulation is used to ensure low capacitance, which is vital for maintaining the cable’s 120-Ohm characteristic impedance over long distances.

Dual-Shielding Architecture:

Beldfoil® Shield: 100% coverage aluminum/polyester foil provides comprehensive protection against high-frequency interference.

Tinned Copper Braid: An overall tinned copper braid provides high structural strength and protects against low-frequency magnetic interference, ensuring stable ground continuity.

Drain Wire: Integrated tinned copper drain wire simplifies the grounding process during termination.

Outer Jacket: A robust, flame-retardant PVC jacket, typically designed to meet rigorous industrial standards for mechanical protection and environmental resistance.

Primary Applications
RS-485 Modbus Networks: Ideal for complex automation systems where two-wire or four-wire full-duplex communication is required.

Multi-Channel Instrumentation: Frequently used for connecting multiple sensors, actuators, and controllers in distributed control systems (DCS).

Industrial Connectivity: Suitable for factory automation, HVAC control, and building management systems requiring high-reliability data paths that are shielded against industrial noise.
