Yes, LBS offers pre-assembled XLR terminated DMX512 lighting control cables on request. Please confirm your connector specification, length and quantity.
Yes, the LBSDMX64025 uses high-density OFC spiral shielding (85%+ coverage) and a twisted-pair construction suitable for balanced DMX512 lighting control and line-level audio signals.
Compare the LBSDMX DMX512 lighting control cable models to match the conductor size to your run length:
| Model | Braiding (cores × conductor) | Typical use | Product page |
|---|---|---|---|
| LBSDMX64025 | 64 / 2 × 0.25 | Short DMX fixture drops, patch | Current page |
| LBSDMX96035 | 96 / 2 × 0.35 | Standard DMX runs | View |
| LBSDMX128035 | 128 / 2 × 0.35 | Longer DMX runs, daisy chains | View |
| LBSDMX144050 | 144 / 2 × 0.50 | Heavy-duty touring, long runs | View |
Multichannel stage snakes from 4 to 48 channels are also available in the LBSDMX multichannel series.
DMX512 runs on the RS-485 electrical layer. RS-485 is specified around a 120 Ω nominal characteristic impedance on shielded twisted-pair cable, and impedance comes from the construction — conductor spacing, insulation and shield geometry — not from the copper size alone.
LBS publishes 120 Ω on the double-shielded LBSDMX…-2 models. On this single-shielded model the published data sheet states shield type, braiding, jacket O.D. and temperature range, and does not state an impedance figure. If your project documentation has to carry one, request the value against this model instead of assuming it.
Why the figure matters: DMX termination and daisy-chain rules →
LBS builds two DMX512 families with the same two conductors, the same 6.3 mm matt EPVC jacket and the same -20 °C to +70 °C rating. The difference is the shield, and that is the line the purchase order has to be specific about.
| Construction | Shield | Impedance on the published data sheet | Model example |
|---|---|---|---|
| Single-shielded (this page) | High-density OFC spiral, 85%+ coverage | Not stated | LBSDMX64025 |
| Double-shielded | 100% coverage AL-Foil plus heavy-duty tinned-copper braid | 120 Ω | LBSDMX64025-2 |
Where the run shares a tray, a truss or a cable path with dimmer racks, LED power supplies or motor drives, the foil layer under the braid is the reason to specify the double-shielded construction. Where the data pair is routed clear of that equipment, the single-shielded spiral is the simpler build and the usual choice.
