UL2651

Product Overview: UL2651 28AWG*6P Flat Ribbon Cable PVC Insulated Cable

The UL2651 flat ribbon cable is engineered to deliver reliable signal transmission and efficient space utilization within complex electronic assemblies. Constructed with premium stranded tinned or bare copper conductors, this cable ensures optimal conductivity and resistance to oxidation over extended periods. The conductors are encased in an eco-friendly PVC insulation layer, formulated to provide a smooth, flexible tactile feel while maintaining strict dimensional stability. Featuring a precise 1.27mm (0.050") pitch, the cable aligns flawlessly with standard Insulation-Displacement Connectors (IDC), facilitating rapid and secure mass termination without the need for individual wire stripping. This structural precision minimizes the risk of connection failures and significantly accelerates the assembly process for electronic manufacturers.

① Thermal Endurance: Rated temperature: 105ºC. Engineered to maintain structural integrity and electrical performance in demanding thermal environments, the insulation resists degradation, cracking, or melting when exposed to elevated operational heat. This thermal stability is crucial for densely packed enclosures where heat dissipation is limited, ensuring long-term reliability in continuous-duty applications.

② Electrical Capacity: Rated voltage: 300V. Provides consistent power and signal transmission across various electronic circuits. The high dielectric strength of the PVC insulation prevents electrical leakage and cross-talk between adjacent cores, securing signal integrity even in environments with potential electromagnetic interference.

③ Regulatory Compliance: Reference Standard: UL758, UL1581, C22.2 No.210. Manufactured to meet rigorous international safety directives, this ribbon cable also strictly adheres to RoHS and REACH environmental guidelines. By eliminating hazardous substances, it supports sustainable manufacturing practices while meeting the compliance requirements of global markets.

④ Fire Resistance: Passes UL VW-1 & CSA FT1 vertical flame test. The specially formulated insulation acts as a reliable barrier against ignition. In the event of an electrical fault or external fire source, the material is designed to self-extinguish rapidly, preventing the spread of flames and protecting critical internal components from catastrophic damage.

⑤ Processing Efficiency: Uniform insulation thickness of wire to ensure easy stripping and cutting. This precise concentricity guarantees that automated processing equipment can cleanly slice through the PVC without nicking or damaging the underlying copper strands. The predictable dimensions reduce setup time, minimize material waste, and optimize the overall efficiency of wire harness production lines.

⑥ Application Versatility: For internal wiring of electronic and electrical equipment and appliance. Specifically designed for compact and constrained spaces, its flat profile allows for neat routing and improved airflow within enclosures. It is widely utilized for efficient signal transmission in computer motherboards, lighting fixtures, automation control systems, and precision measuring instruments.
