PROEL HPC862FR - 75 Ohm Double Shielded Coaxial Cable for Video and Word Clock
The Proel HPC862FR is a high-precision coaxial cable specifically designed to meet the critical demands of digital audio and video signal transmission and synchronization. In professional environments where signal integrity is paramount, this cable excels in maintaining consistent impedance and rejecting external interference, ensuring your equipment operates in perfect harmony.
Manufactured to Proel's stringent quality standards, the HPC862FR combines premium materials with robust construction. Its oxygen-free copper (OFC) conductor core ensures pristine transmission, while its double-braid architecture acts as an impenetrable barrier against electromagnetic interference (EMI) and radio frequency interference (RFI), common in recording studios, stages, and broadcast rooms. Whether distributing a master clock signal or for composite video, this cable delivers the reliability required for large-scale projects.
Main features
-
75 Ohm Steady Impedance: Essential to avoid signal reflection and "jitter" in digital transmissions, ensuring precise synchronization between devices.
-
Double Shielding (Double Mesh): Incorporates a first layer of aluminum foil followed by a dense braided tinned copper mesh. This combination offers over 100% coverage, protecting the signal even in environments with high electrical noise.
-
High Purity Conductor: The central core uses high conductivity copper, minimizing signal attenuation over long runs.
-
Flexible and Durable Cover: Its outer coating is designed to withstand the mechanical stress of mobile or fixed installations, while maintaining flexibility for easy handling and rolling.
-
Application Versatility: Optimized for both analog video signals and critical digital sync signals.
Benefits for the professional
For systems engineers and audiovisual integrators, the Proel HPC862FR solves one of the most common problems in the studio: digital clock instability. By using this cable for Word Clock connections, the risk of clicks, pops, and desynchronization between audio interfaces and converters is drastically reduced. Furthermore, its double-shielded construction ensures that nearby power lines or stage lighting do not interfere with the video or sync signal, providing a clean image and rock-solid digital audio.
Use cases
-
Studio Synchronization (Word Clock): BNC connection between audio interfaces, digital preamplifiers and master clock generators.
-
Video Broadcast and CCTV: Transmission of composite video or SDI signals (over short/medium distances depending on bandwidth) in television studios and mobile units.
-
Fixed Installations: Structured cabling in auditoriums, theaters and conference rooms where safety and durability certification is required.
-
Equipment Rack: Interconnection of video equipment and signal processors within technical racks.
Frequently Asked Questions
-
Is this cable suitable for standard analog audio signals (RCA)?
Although it can physically transmit audio, it's a 75-ohm coaxial cable designed for video and digital signals (SPDIF/Word Clock). For analog microphone or line audio, 110-ohm balanced or standard audio cables are recommended.
-
What does "Double Mesh" mean?
This means the cable has two layers of shielding around the center conductor. Typically, this consists of an aluminum foil and a copper braid. This is far superior to simple shielded cables at blocking interference.
-
Can it be used for TV antennas?
Yes, being a 75 Ohm coaxial cable, it is technically compatible with RF signals, although its "flexible" design is more geared towards patch cords and equipment connections than long, rigid antenna downleads.
Project description
Professional 75 Ohm coaxial cable, model HPC862FR. Construction consists of a high-purity copper center conductor, polyethylene (PE) dielectric insulation, and a double shielding system comprised of 100% aluminum foil and high-density tinned copper braid. The outer jacket is made of flexible, abrasion-resistant PVC with flame-retardant properties (FR variant). Specifically designed for transmitting video signals, word clock synchronization, and coaxial digital audio.
