Liberty AV 24-4P-P-L6-EN-BLK 500 500' Black Category 6 U/UTP EN Series 23 AWG 4 Pair Unshielded Cable

Product Overview

The Liberty AV 24-4P-P-L6-EN-BLK is a 500-foot reel of Category 6 U/UTP EN Series plenum-rated bulk cable built for commercial AV and IT infrastructure installation in air-handling spaces. Constructed with 23 AWG solid annealed bare copper conductors, high-density polyethylene insulation, and a plenum-rated PVC jacket, this cable meets ANSI/TIA-568C Category 6 performance and NEC CMP requirements for direct installation in plenum spaces without conduit. The 500-foot reel format suits medium-to-large conference room buildouts, floor-level horizontal runs, and HDBaseT AV distribution infrastructure where LAN, IP control, and video-over-IP cabling share the same pathways.

Product Description

The 24-4P-P-L6-EN-BLK is part of Liberty AV's EN Series commercial Cat6 cable line, third-party certified to ANSI/TIA-568C Category 6 performance by both UL and ETL. The plenum (CMP) rating qualifies this cable for installation in HVAC air-handling plenum spaces common in commercial office and government buildings, without the need for conduit. The 23 AWG solid bare copper conductors provide reliable conductivity and consistent electrical characteristics across the full run length, and the pairs are twisted in varying lay lengths to minimize crosstalk.

The cable is tested to 550 MHz with a positive ACR (Attenuation-to-Crosstalk Ratio) spec to 550 MHz, exceeding the standard Cat6 test frequency of 250 MHz and providing headroom for HDBaseT and other bandwidth-sensitive commercial AV applications. Electrical parameters include an impedance of 100 ± 15 ohms, propagation delay skew of 45ns/100m maximum, and a velocity of propagation of 68%. A ripcord under the jacket simplifies termination at patch panels and keystone jacks. The 0.240" outside diameter cable pulls cleanly through standard commercial conduit and cable trays. At 500 feet, this reel is well-matched to floor-level horizontal distribution or multi-zone conference room AV infrastructure without the excess of a 1,000-foot reel. The cable is RoHS compliant and rated for installations in accordance with NEC Articles 725 and 800. It supports LAN runs up to 300 feet at 10/100/1000BaseT and passive balun runs up to 2,500 feet for AV distribution applications. Compatible termination hardware includes Liberty's FTPU60A field-terminable RJ45 connectors and K6-8KP keystone inserts.

Key Features

• NEC CMP Plenum Rated — Certified for direct installation in HVAC air-handling plenum spaces without conduit, meeting NEC CMP and CEC CMP FT6 fire code requirements.
• ANSI/TIA-568C Category 6 Certified — Third-party certified by UL and ETL to Cat6 performance standards; tested to 550 MHz with positive ACR spec.
• 23 AWG Solid Bare Copper Conductors — Solid annealed bare copper provides stable DC resistance (≤20.3 Ω/1000') and consistent signal characteristics across full run lengths.
• High-Density Polyethylene Insulation — HDPE insulation on each conductor minimizes capacitance (14.0 pF/ft) and supports the cable's 550 MHz performance specification.
• Varying-Lay Twisted Pairs — Four pairs twisted in varying lay lengths reduce near-end crosstalk (NEXT) and interference between pairs.
• Ripcord Under Jacket — Integrated ripcord simplifies jacket removal for fast, clean termination at patch panels and keystones.
• HDBaseT and Passive Balun Support — Supports LAN runs to 300 feet and passive AV balun runs to 2,500 feet for IP control, video over IP, and analog AV distribution.
• 500-Foot Reel Format — Practical mid-size reel for commercial AV floor runs and multi-room installations without full 1,000-foot reel surplus.
• RoHS Compliant — Meets EU RoHS-2 2011/65/EU environmental compliance requirements.

Typical Applications

Technical Specifications

Frequently Asked Questions

What is the difference between this cable and the riser (CMR) version?

The 24-4P-P-L6-EN-BLK uses a plenum-rated PVC jacket (NEC CMP), which is required for installation in HVAC air-handling plenum spaces in commercial buildings. The riser-rated CMR version (24-4P-L6-EN-BLK) is for vertical runs in riser shafts but is not approved for plenum spaces. Always specify CMP when the cable pathway passes through air-handling ceiling spaces or open plenums in commercial construction.

Is this cable suitable for HDBaseT extender runs in conference rooms?

Yes. Liberty AV rates this cable for passive balun and HDBaseT runs up to 2,500 feet, well beyond the standard 100-meter HDBaseT channel length. The 550 MHz test frequency and Cat6 certification provide sufficient bandwidth headroom for 1080p and 4K HDBaseT applications. For active HDBaseT extenders, follow the extender manufacturer's specific cable requirements, but Cat6 CMP is the standard specification for commercial HDBaseT deployments.

Can this cable be used for Power over Ethernet (PoE) applications?

Yes. The 23 AWG solid bare copper conductors support PoE applications. The cable is rated at a maximum current of 1.4A at 25°C per the electrical specifications. Verify total power budget and heat dissipation requirements with your PoE switch manufacturer for bundled PoE cable runs in plenum spaces.

What termination hardware is compatible with this cable?

Liberty AV's FTPU60A field-terminable Cat6 RJ45 connector and K6-8KP keystone inserts are recommended accessories for this cable line. Standard Cat6 punch-down keystone jacks and patch panel terminations from any major manufacturer are compatible. The integrated ripcord simplifies jacket removal for fast field termination.

What is the outside diameter and conduit fill for this cable?

The cable has an outside diameter of 0.240" (6.10mm). Use Liberty AV's Conduit Calculator (available on their website) to determine conduit fill ratios for multi-cable runs. Standard commercial installation practice limits conduit fill to 40% for three or more cables per NEC Chapter 9.

Does this cable meet UL and ETL certification requirements?

Yes. The 24-4P-P-L6-EN series is third-party certified to ANSI/TIA-568C Category 6 performance by both UL and ETL, in addition to meeting NEC CMP and EU RoHS-2 compliance. Certification documentation is available from Liberty AV Solutions or through Creation Networks.
