Frequently Asked Questions
Can I use this standard XLR cable for both Microphone audio and DMX lighting control?
For short distances, a standard analog audio XLR cable will work for DMX lighting. However, for professional, long-distance DMX runs, we manufacture these assemblies using 120-ohm impedance cable specifically designed to handle the high-frequency digital data of DMX512, preventing signal reflection and flickering lights.
Do you offer custom jacket materials for outdoor or harsh environments?
Yes. While standard PVC is excellent for indoor studios, we offer PUR (Polyurethane) jackets for outdoor festivals or industrial applications. PUR is highly resistant to abrasion, oil, UV light, and extreme temperatures.
Can you customize the cable lengths and connector boot colors?
Absolutely. As an OEM factory, we can produce any custom length required. We also offer color-coded strain relief boots or custom logo heat-shrink tubing to help you easily identify signal routing in complex AV setups.
Are your XLR cable assemblies CE and RoHS certified?
Yes, all our raw cables and connectors are manufactured using environmentally friendly materials and are fully compliant with CE, RoHS, and REACH directives for immediate distribution in European and North American markets.
What is the Minimum Order Quantity (MOQ) and production lead time?
Our MOQ for standard lengths and specifications is very flexible to support your trial orders. For volume OEM orders with customized branding, the lead time is typically 3 to 4 weeks depending on the required jacket material and total quantity.
Overview and Application Notes
Overview
Engineered for flawless analog signal transmission and high-frequency digital DMX512 lighting control, our 3-Pin XLR Male to Female DMX Cable Assemblies offer robust electrical reliability for harsh event and broadcast environments. Manufactured under strict IEC 61076-2-103 standards, this assembly features precision brass contacts with gold plating for minimal contact resistance ($\le 10\text{ m}\Omega$), high-density braided tinned copper shielding to mitigate EMI/RFI, and a nominal 120-ohm impedance optimized for data integrity. As a factory-direct OEM/ODM provider, we deliver flexible cable length customization, custom color-coded strain relief boots, and full IPC-A-620 compliant assembly quality tailored for distributors and equipment manufacturers worldwide.
Application Notes
-
Impedance Compliance for DMX: Built with a tuned 120-ohm characteristic impedance specifically designed to prevent signal reflections and data loss in high-speed DMX512 daisy-chain setups.
-
Voltage & Current Ratings: Operating range strictly rated for under 2.4V AC signals (compatible with standard RS-485/DMX differential signals and low-voltage mic signals) with a maximum current capacity of 3A.
-
Bend Radius Rules: Adhere to minimum installation bend radius limits—8x Cable OD for fixed installations and 10x Cable OD for flexible stage routing—to maintain internal braid geometry and long-term durability.
-
Pinout & Polarity: Pinout is mapped 1-to-1 (Pin 1: Ground/Shield, Pin 2: Data-/Hot, Pin 3: Data+/Cold) to ensure drop-in compatibility across standard 3-pin XLR audio and stage lighting interfaces.
-
Quality Assurance: 100% factory tested for open circuits, short circuits, and miswiring at DC 300V insulation resistance conditions before shipment.
