Frequently Asked Questions
How do I specify the length for a coiled HDMI cable?
When submitting an RFQ, please reference our engineering drawing to provide the specific dimensions you need: the straight tail lengths at both ends (Length A and C), and the working length of the coiled section (Length B - both retracted and extended). We can customize all these dimensions according to your product's mechanical design.
What is the difference between a PVC and TPU jacket for spring cables?
For coiled cables, TPU (Thermoplastic Polyurethane) is highly recommended over PVC. TPU offers superior elasticity, better resistance to wear and tear, and maintains its tight coiled shape (memory retention) much longer after repeated stretching.
Does this cable support 4K video resolution?
Yes, our high-speed Type A to Mini Type C HDMI cables are engineered to HDMI 2.0 standards, supporting 4K@60Hz resolution, HDCP 2.2, and 18Gbps bandwidth.
Can we customize the connector angles or request Micro HDMI (Type D) instead?
Absolutely. As a direct OEM manufacturer, we can modify the tooling to include right-angle connectors, or replace the Mini HDMI (Type C) with a Micro HDMI (Type D) or a standard Type A connector based on your device's interface.
Overview and Application Notes
Overview The High-Speed HDMI Spring Pre-Molded Cable features a highly durable coiled design, offering exceptional flexibility and space management for dynamic electronic environments. Engineered to connect standard HDMI (Type A) displays to devices equipped with Mini HDMI (Type C) ports, this cable supports high-definition video and high-speed data transfer. Based on our standard engineering drawing, the assembly features premium Black PVC overmolding for reliable performance. At EDOM Electronics, we provide fully customizable OEM solutions, allowing you to specify the exact retracted, extended, and tail lengths (Dimensions A, B, and C) to perfectly match your specific mechanical and routing requirements.
Application Notes
-
Dynamic Flexibility: The coiled spring design prevents cable clutter and dragging, making it perfect for moving equipment like camera gimbals, robotic arms, and adjustable medical workstations.
-
Installation & Bending Radius: To maintain signal integrity and prevent internal conductor fracture, adhere to our standard engineering parameters: ensure a minimum bending radius of 8x the cable’s outer diameter (OD) for fixed installations, and 10x the cable OD for dynamic/flexible installations.
-
Port Identification: Please note this cable features a Mini HDMI (Type C) connector, which is smaller than standard HDMI but larger than Micro HDMI (Type D). Ensure your host device matches this specification.
