Frequently Asked Questions
How do I specify the length for a coiled HDMI cable?
When submitting an RFQ, please provide two measurements: the retracted length (when the cable is coiled and resting) and the maximum extended length (the working stretch distance). We can customize both 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 4K video and high-speed data transfer. At EDOM Electronics, we provide fully customizable OEM solutions, allowing you to specify the retracted/extended lengths, coil diameters, and outer jacket materials (such as TPU for superior shape memory). This makes it the ideal connectivity solution for AV distributors, photography equipment brands, and industrial automation manufacturers across Europe and North America.
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.
-
Jacket Material Selection: While PVC is available for standard use, we highly recommend selecting a TPU (Thermoplastic Polyurethane) outer jacket during your RFQ for applications requiring high elasticity and long-lasting shape memory after repeated stretching.
-
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.
