3M HF365 Series Round Conductor Flat Cable, 20 Conductors, 100ft Length, Halogen-Free - HF365/20SF
This round conductor flat cable provides a compact, flexible means of linking multiple circuits in automation and electronics assemblies. Designed for multiway connections, it combines numerous individually insulated conductors arranged in a flat configuration to simplify routing in confined harnessing channels and machine enclosures.

How is the conductor configured to withstand repeated flexing?
Each conductor is MADE from seven fine strands of tin-plated copper, which increases flexibility compared with solid wire and helps distribute mechanical stress during cyclical movement.
What does the outer material deliver in practical terms?
The jacket is a polyolefin compound that resists abrasion and maintains insulation integrity while exhibiting low-smoke, zero-halogen behaviour under fire conditions.
How does the cable suit connector density constraints?
The conductors are spaced at a 1.27mm pitch in a flat format, allowing tight alignment with small-pitch connector systems and saving space within harness channels.
What environmental temperature limits should be observed during installation?
Installation and operation should remain within the specified -40°C minimum and 105°C maximum to preserve conductor and jacket properties.
What electrical load can each core carry safely?
The cable is specified for use up to a 300V system, making it appropriate for many signal and control voltage applications within that limit.
