双屏蔽重型 DMX512 灯光控制线 - 168/2×0.50

Features

• Full-Coverage Dual-Layer EMI/RFI Protection: Combines a 100% coverage AL-Foil shield (against high-frequency noise) with a heavy-duty tinned copper braid/spiral (against low-frequency EMI) for maximum signal purity.
• Ultra-Low Loss Long-Distance Transmission: Preserves strict 120 Ω characteristic impedance across long runs, effectively preventing timing jitter, data packet drops, and signal degradation.
• Industrial-Grade Interference Rejection: Engineered to withstand harsh electromagnetic interference from nearby high-voltage conduits, LED power drivers, and stage dimmer racks.
• Tour-Grade Mechanical Durability: The dual-shield layer drastically enhances crush resistance, tensile strength, and inner core protection under heavy stage foot traffic.

Applications

• Large-scale outdoor live concerts, stadium touring rigs, and long-distance multi-fixture DMX512 daisy-chain networks.
• High-density cable trays running alongside heavy power distribution cables, theater grid installations, and TV/broadcast van routing.
• Mission-critical Pro-AV and staging projects where signal interruption or fixture flickering is completely unacceptable.

OEM and Customisation for Double-Shielded DMX Lighting Control Cable

LBS supplies double-shielded DMX512 lighting control cable as bulk cable for OEM, ODM and project orders. Customisation options include jacket colour (black / brown / dark green), brand and model printing on the jacket, cut lengths, and packaging format. Send your specification and quantity for a quotation.

Double-Shielded vs Single-Shielded DMX512 Lighting Control Cable

LBS publishes its DMX512 lighting control cable range at two shielding levels on the same 2-core twisted-pair construction. This page is the double-shielded heavy-duty level — a 100% coverage AL-Foil shield plus a heavy-duty tinned-copper braid over 2-core 4N OFC conductors, a 6.3 mm matt EPVC jacket and a 120 Ω characteristic impedance, for long-distance stage lighting runs. The single-shielded 168 / 2 × 0.50 equivalent (LBSDMX168050-1) uses a high-density OFC spiral shield instead and suits short and medium runs.

LBSDMX Double-Shielded DMX512 Lighting Control Cable Series — Variants

Compare the double-shielded models to match the braid density and conductor size to your run length:

Single-shielded DMX512 cable for short and medium runs is in the single-shielded DMX512 range; multichannel stage snakes from 4 to 48 channels are in the LBSDMX multichannel series.

FAQ

Which connector is used on a DMX512 lighting control cable?

DMX512 lighting control links are standardised on 5-pin XLR connectors (ANSI E1.11); 3-pin XLR is also found in practice on short, non-critical links. This page is bulk cable — LBS can also quote pre-assembled XLR terminated DMX512 lighting control cables. Confirm your connector type, length and quantity when you request the specification.

What is the difference between the single-shielded and double-shielded models?

Single-shielded models (LBSDMX…-1) use a high-density OFC spiral shield. Double-shielded models (LBSDMX…-2, this page) add a 100% coverage AL-Foil layer under a heavy-duty tinned-copper braid. Both are 2-core twisted-pair DMX512 cable with a 120 Ω characteristic impedance.

Can this cable also be used for balanced audio?

The construction is a 2-core twisted, shielded pair, which is why it is often compared with microphone cable; it is specified here for DMX512 lighting control. For microphone and line-level audio links use the LBSMIC microphone range.
