3M HF365 Series Round Conductor Flat Cable, 100ft Length, 40 Conductors, Halogen-Free - HF365/40SF

This round conductor flat cable provides Compact multi‑way wiring for electronic and automation systems, delivering a flexible, unshielded connection suited to dense interconnects. It is intended for applications requiring multiple conductors in a slim, ribbon‑style format and operates across a wide temperature range for demanding industrial environments.

Features & Benefits

• 40 conductors increase wiring density for complex assemblies
• 28 AWG stranded tin‑plated copper improves Flex life and conductivity
• 1.27mm pitch enables precise connector alignment and routing
• Polyolefin dark grey jacket offers chemical resistance and durability
• LSZH halogen‑free construction reduces toxic smoke in fire events
• Maximum operating temperature 105°C supports high‑heat installations

Applications

• Suitable for backplane to daughterboard interconnects in control racks
• Ideal for cable runs inside automation cabinets and enclosures
• Used with ribbon connectors for industrial sensor arrays
• Can be used for wiring harnesses in electrical test rigs
• Used for signal routing in mechanical motion controllers

How flexible is the cable for repeated movement applications?

The conductors are stranded with seven strands per core, enhancing flexibility for applications requiring frequent bending.

What environmental temperature extremes can it tolerate?

It is specified to operate down to −40°C and up to 105°C, supporting cold storage and high‑temperature zones.

Is the cable suitable for screened or noise‑sensitive circuits?

The construction is unshielded, so additional screening or earthed trays are recommended for EMI‑sensitive installations.

How long is each reel and how does that affect procurement?

Each length is supplied as 100 ft, allowing planners to calculate runs and minimise jointing in assemblies.
