3M HF539 Series Ribbon Cable Flat 1.27 mm Pitch 26 Conductors 30.48 m Length HF539

3M HF539 Series Ribbon Cable HF539 is a flat, multi-conductor cable featuring 26 conductors arranged at a 1.27 mm pitch, extending 30.48 meters in length. This cable offers a compact and flexible interconnect solution ideal for industrial, electronic, and automation system applications where space saving and reliable mass termination are crucial.

The conductors are made of 28AWG stranded tinned copper round wire, providing enhanced flex life and fatigue resistance suitable for dynamic environments. A polyolefin jacket with a high-flex formulation encases the cable, delivering resistance to repeated movement and mechanical stress.

The cable's low smoke zero halogen (LSZH) composition significantly reduces toxic emissions, supporting safer use in enclosed or constrained areas. It is rated for 300 volts, making it suitable for general control and signal voltage uses within control panels, instruments, harness assemblies, and robotics systems.

Operating reliably in temperature extremes from minus 40 degrees Celsius to 105 degrees Celsius, this cable maintains electrical performance under rigorous conditions. Its 1.27 mm pitch matches widely used IDC and ribbon connector spacing, facilitating straightforward, predictable wiring and terminations.

This version is unscreened; thus, additional external shielding is advised where electromagnetic interference immunity is critical. The product meets applicable international standards including RoHS compliance, IEC 61249-2-21, and UL listing (UL File No: E42769, Style 21682), ensuring safety and quality assurance.

Features 26 conductors for dense parallel signal routing. 28AWG stranded conductors improve flex life and fatigue resistance. Polyolefin high-flex jacket resists mechanical stress. Low smoke zero halogen composition reduces toxic emissions.

Rated for 300 V control and signal voltages. Wide operating temperature range from -40°C to 105°C. Standard 1.27 mm pitch for compatibility with IDC connectors. Unscreened cable with options for external EMI shielding. Complies with RoHS, IEC 61249-2-21, and UL standards.

This cable is ideal for use in internal wiring of automation control panels, test rigs, multi-signal harnesses, robotic assemblies, and other industrial electronic systems requiring flexible, safe, and reliable ribbon cable solutions.
