3M HF365 Series Round Conductor Flat Cable, 20 Conductors, 100ft Length, Halogen-Free - HF365/20


This round conductor flat cable is designed to provide organised multi‑core signal wiring in industrial and telecommunications environments. It combines multiple conductors in a flat ribbon format to simplify routing in confined spaces while maintaining electrical separation between 20 circuits. The dark grey, flexible assembly suits panel interconnects and internal harnessing where a compact, flame‑safer cable is required.

Features & Benefits


• 28AWG stranded conductors for improved Flex life and conductivity
• Tin‑plated copper round conductors to resist corrosion during installation
• 20 conductors with 1.27mm pitch to aid dense connector termination
• Polyolefin jacket with LSZH composition to reduce toxic emissions
• Rated 300V for low‑voltage control and signal circuits
• Operating range −40°C to 105°C for elevated temperature environments

**Applications**


• Suitable for control cabinet internal wiring in automation systems
• Ideal for ribbon connector wiring in telecom equipment racks
• Used for interconnects between sensors and data acquisition modules
• Can be used for harnesses in machinery with constrained routing paths

How does strand count affect cable durability during frequent flexing?


Each conductor comprises seven strands which distribute mechanical stress and enhance resistance to fatigue compared with solid cores, reducing the risk of breakage in flexing routes.

What performance does the jacket material provide against chemical exposure?


The polyolefin sheath offers general resistance to oils and common industrial solvents, helping to preserve insulation integrity in plant environments.

Is this cable screened for EMI protection?


The design is unscreened, so external screening or routed segregation should be used where electromagnetic interference suppression is required.

How long is a standard supply length and how does that influence installation planning?


The cable is supplied in 100 ft lengths, enabling long runs without joins, reducing potential connection points and associated installation time.
