Belden 5509UE is a commercial-grade, multi-conductor unshielded security and audio cable engineered for high-density, low-voltage installations in commercial and residential settings. Featuring 12 independent 22 AWG conductors, 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. It offers a balance of flexibility, density, and safety for complex interconnect arrays.
Key Features of Belden 5509UE
High-Density Multi-Conductor Build: Packages 12 discrete 22 AWG circuits into a single, cohesive cable profile, minimizing installation labor and streamlining wire management behind panels and racks.
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 Bare Copper: Manufactured with premium, solid bare copper conductors. Solid copper provides maximum signal integrity, lower DC resistance over long distances, and reliable punch-down or screw-terminal terminations.
Premium Polyolefin Insulation: Conductors are wrapped in a high-dielectric polyolefin 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 Systems: Interconnecting multi-zone alarm control panels, high-density keypad arrays, motion detectors, and biometric access control readers.
Intercom & PA Systems: Routing multi-station audio, paging grids, and master control voice lines in schools, hospitals, and office complexes.
Sound & Audio Distribution: Connecting multi-channel background music systems, low-voltage speaker zones, and localized audio controls.
Background Control & Signaling: Distributing discrete low-voltage digital signals, relay controls, HVAC sensor networks, and building automation commands.

Technical Note: Because Belden 5509UE is an unshielded cable with solid conductors, it is optimized for fixed, permanent installations within walls or conduits. It should not be utilized in applications requiring continuous flexing, such as inside robotic tracks or on moving machinery. Additionally, 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).
CABLE TYPE: 22 AWG / 12-Conductor Unshielded Riser Cable
