PROEL DMX - Balanced DMX Installation Cable with Flame Retardant Sheath (5 mm)
The PROEL DMX installation cable is a professional, high-engineering solution specifically designed for critical data transmission in digital lighting and control systems. Unlike standard microphone cables, which are often misused for DMX, this cable is manufactured with a constant and precise impedance (nominal 120 Ohms), ensuring that the digital signal travels from the console to the luminaires without reflections, data loss, or the dreaded flicker in the equipment.
One of the most outstanding features of this model is its physical construction, designed for architectural integration. With a reduced outer diameter of approximately 5 mm , it is extremely easy to route through narrow ducts, channels, and suspended ceilings where space is limited. Despite its slim profile, it does not compromise on durability or protection; it features a high-quality, fire-retardant outer casing . This safety feature is essential for permanent installations in theaters, auditoriums, and public buildings, complying with fire safety regulations by slowing the spread of flames.
Inside, the cable houses two high-purity copper conductors , optimized to maintain signal integrity over long distances. Protection against electromagnetic interference (EMI) and radio frequency interference (RFI) is ensured by a robust shielding system, which typically combines a braided mesh with a protective foil. This ensures that the cable can be installed near power lines without suffering from noise contamination that could affect the DMX512 protocol.
Main features
-
Stable Impedance: Designed specifically under the DMX512 standard (120 Ohms nominal) for perfect bit-by-bit data transmission.
-
Installation Profile: Its 5 mm diameter facilitates routing in complex spaces and termination in low-profile XLR connectors or terminal blocks.
-
Certified Safety: The outer shell is made with fire-retardant compounds, essential to comply with building codes in permanent installations.
-
High Flexibility: Despite being an installation cable, it maintains adequate flexibility to be handled in corners and racks without damaging the internal conductors.
-
Effective Shielding: The protective mesh ensures superior rejection of electrical noise, vital in stage environments full of dimmers and power supplies.
Benefits for the integrator and the end user
For the systems integrator, this cable eliminates the usual headaches during the wiring phase. Its flame-retardant jacket and reduced diameter expedite project certification and cable routing through saturated conduits. For the end user, the benefit translates into absolute reliability during the show: the lights respond precisely when they should, without delays or erratic behavior caused by low-grade cables.
Use cases
-
Theaters and Auditoriums: Fixed cabling from the control booth to the lighting bars and stage boxes.
-
Architectural Lighting: Control of LED facades and home automation systems that require cable passage through walls and ceilings.
-
Television Studios: Facilities where signal clarity is critical and there is a large amount of surrounding electronic equipment.
-
Hospitality Facilities: Nightclubs and event venues that require strict compliance with fire safety regulations.
Frequently Asked Questions
Can I use this cable for analog audio signals?
Yes, although it is optimized for high-frequency DMX digital data, its balanced and shielded construction allows for the transmission of analog audio with excellent quality and very low noise.
Is it compatible with 3-pin and 5-pin XLR connectors?
Absolutely. Being a 2-conductor cable plus shield (ground), it is fully compatible for soldering onto both 3-pin XLR connectors and the standard 5-pin DMX protocol connectors.
What does it mean for the roof to be fireproof?
This means that the outer jacket material has been chemically treated to resist combustion and not spread fire in the event of a fire, a common requirement in public building safety regulations.
Project description
Balanced data cable specifically designed for DMX512 protocol and fixed installations. It features a twisted-pair construction with two internal copper conductors and high-density braided shielding for interference rejection. It has a nominal characteristic impedance of 120 Ohms and low capacitance for long-distance digital signal transmission. The outer jacket is made of flame-retardant PVC with a reduced outer diameter of 5 mm, optimized for routing through conduits and narrow raceways.
