Belden 5341UE 18 AWG 2 Pair Unshielded Sound & Security Cable | CMR Riser Rated

Belden 5341UE is a commercial-grade, multi-paired unshielded security and audio cable engineered for multi-circuit, low-voltage installations requiring a heavier current capacity or lower resistance than standard 22 AWG wire. Featuring 2 pairs (4 independent conductors total) of 18 AWG wire, this cable is UL-rated as CMR (Communications Riser), making it safe and compliant for vertical installations between floors, inside riser shafts, or within walls. By twisting conductors into distinct pairs, it provides a high degree of natural noise rejection for multi-line low-voltage arrays.

Key Features of Belden 5341UE

• Heavy-Duty 18 AWG Wire Gauge: Built with larger 18 AWG conductors to support longer cable runs and higher current demands with minimal voltage drop, making it ideal for critical low-voltage power and signaling pathways.

• Paired Architecture for Cross-Talk Reduction: Features 2 pairs twisted together to minimize inductive coupling and cross-talk between signal channels. This provides cleaner data and audio transmission compared to standard straight parallel multi-conductor cables.

• CMR Riser Safety Rating: Certified with a UL 1666 Riser rating. The flame-retardant PVC jacket is engineered to prevent the spread of fire vertically from floor to floor, satisfying strict commercial building code requirements.

• Highly Conductive Stranded Copper: Manufactured with premium stranded bare copper conductors (7 x 26 stranding layout). This stranded configuration delivers exceptional physical flexibility, making it easy to route around tight corners and through complex structural cavities.

• Premium Polypropylene Insulation: Conductors are wrapped in a high-dielectric polypropylene (PP) insulation. This formulation ensures stable electrical performance and prevents physical conductor-to-conductor shorts within the tight bundle.

• Rip Cord Integration: Includes a built-in nylon rip cord beneath the jacket, allowing installers to easily score and strip back long sections of the outer sheath without risking damage to the inner conductor insulation.

Common Applications

• Commercial Security & Access Control: Interconnecting multi-zone alarm control panels, keypad arrays, door strikes, magnetic locks, card readers, and biometric access control hardware requiring low-voltage power supply loops.

• Intercom & PA Systems: Routing multi-station audio, balanced paging lines, and master control voice networks in schools, hospitals, and office complexes.

• Sound & Audio Distribution: Connecting high-fidelity background music systems, low-voltage speaker zones, and localized audio control attenuators where a larger gauge is needed to preserve audio quality.

• Background Control & Signaling: Distributing discrete low-voltage digital signals, power-limited relay controls, HVAC sensor networks, thermostat zones, and industrial automation commands.

Technical Note: Because Belden 5341UE is an unshielded cable, it relies entirely on its twisted-pair design to combat cross-talk between internal channels, but it lacks an overall metallic barrier against severe external high-frequency electromagnetic interference (EMI). To avoid signal degradation, noise coupling, or data corruption, do not route this low-voltage cable parallel to high-voltage AC power lines (120V/240V or higher) within the same wall cavity or conduit unless separated by an approved physical barrier or a minimum distance of 50 mm (2 inches). If your layout requires installation through drop ceilings utilized for environmental air exchange, the plenum-rated equivalent (Belden 6341UE) must be used instead.
