3M 3749 Series Flat Cable, 100ft Cable Length, 80 Conductors - 3749/80 100FT

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.

Features and Benefits:

• 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

Applications

• 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

What conductor construction allows straightforward terminations?

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.

How does the jacket material affect cable handling and routing?

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

Is this cable screened for EMI suppression?

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

What flame behaviour classification applies to this cable?

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