Belden 5305UE 18 AWG 7 Conductor Unshielded Sound & Security Cable | CMR Riser Rated

Belden 5305UE is a commercial-grade, multi-conductor unshielded security and audio cable engineered for multi-circuit, low-voltage control and signal distribution. Featuring 7 independent 18 AWG conductors, this heavy-duty cable handles higher current demands and longer cable runs with significantly less voltage drop than standard 22 AWG options. It is UL-rated as CMR (Communications Riser), making it code-compliant for vertical paths inside riser shafts, between floors, or within walls, bundling multiple zones or control circuits into a single structured pull.

Key Features of Belden 5305UE

• Heavy-Duty 18 AWG Wire Gauge: Built with robust 18 AWG conductors to support longer installation distances and minimize line resistance, ensuring reliable power and signal distribution over extended runs.

• 7-Conductor Distribution Layout: Combines 7 discrete, color-coded circuits under a single outer sheath, drastically lowering physical deployment time, labeling logistics, and conduit congestion compared to pulling multiple individual wire pairs.

• CMR Riser Safety Rating: Certified with a UL 1666 Riser rating. The flame-retardant outer 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 in a 7x26 stranding layout. This design balances robust cross-sectional mass with optimal physical flexibility for neat routing through walls and tight enclosures.

• Premium Polyolefin Insulation: Conductors are wrapped in a high-dielectric polyolefin insulation. This thin-wall formulation delivers superior electrical performance and defense against conductor shorting while keeping the overall diameter slim.

• 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-device access control nodes, keypad arrays, card readers, biometric scanners, and heavy-duty magnetic locks or door strikes requiring low-voltage power supply loops.

• Intercom & PA Systems: Routing multi-station voice paths, balanced paging networks, and master control lines in schools, commercial offices, and healthcare complexes.

• Sound & Audio Distribution: Connecting multi-channel background music networks, low-voltage paging zones, and localized audio controls where line loss needs to be managed over extended distances.

• Background Control & Signaling: Distributing multi-circuit low-voltage digital signals, power-limited relay controls, HVAC sensor loops, thermostat zones, and building automation commands.

Technical Note: Because Belden 5305UE is an unshielded cable, it is highly flexible but lacks defense against 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 6305UE) must be used instead.
