3M 3749 Series Ribbon Cable, Flat, 0.635 mm Pitch, 80, 300 ft Length

This flat cable is a multi-conductor ribbon designed for internal signal and interconnect tasks in electrical, electronic and automation equipment. It provides a compact, parallel conductor layout in a grey thermoplastic elastomer jacket to facilitate neat routing between boards and modules in confined assemblies.

• 80 conductors enhance multi-signal consolidation and wiring density • 30AWG tin-plated copper conductors reduce contact corrosion risk • Solid single-strand round conductors simplify termination reliability • 0.635mm pitch supports fine-pitch IDC and board connections • Rated to 150V for low-voltage signal and control applications • Operating range -40°C to 105°C maintains performance across environments

• Suitable for board-to-board interconnects in automation cabinets • Ideal for IDC connector assemblies in control panels • Used for multi-signal harnessing in electronic test rigs • Can be used for ribbon wiring inside industrial machinery

Each conductor is a single solid strand of tin-plated copper in a round form, enabling reliable crimping and IDC-style termination without stranded-wire fraying concerns.

The thermoplastic elastomer jacket provides a flexible yet Durable outer layer that assists routing through tight channels while resisting abrasion typical in equipment enclosures.

The construction is unscreened, so external screening or routed separation is recommended when used near high-noise power conductors.

The cable meets UL horizontal flame behaviour requirements classified as FT-2 for horizontal flame testing scenarios.
