Type 1:
Knurled Screw Cap HDMI Female to Male Extension Cable
This version uses a threaded protective cap with a knurled exterior surface.The knurled pattern improves grip when manually tightening or removing the cover.
When the HDMI interface is not in use, the cap provides physical coverage for the receptacle.
Available cable lengths:0.3M / 0.5M / 1M
Suitable for industrial control equipment, industrial computers, test systems, and display control equipment.
Type 2
Straight-Ribbed Screw Cap HDMI Female to Male Extension Cable
Product 2 features a straight-ribbed threaded protective cap.
Compared with the knurled version, the cap uses regular longitudinal ribs for a clean mechanical appearance while still providing a practical gripping surface.
The panel side uses an HDMI female receptacle, while the internal cable terminates in an HDMI male plug.
Available lengths:0.3M / 0.5M / 1M
Type 3:
Scalloped Screw Cap HDMI Female to Male Extension Cable
This version features a scalloped screw-cap design.
The scalloped perimeter provides a more pronounced gripping profile compared with conventional knurled or straight-ribbed covers.
This structure can be useful where operators require a clearly defined manual grip.
Available lengths:0.3M / 0.5M / 1M
Type 4:
Hinged Flip Cover HDMI Female to Male Extension Cable
Type 5：
Capless HDMI Female to Male Extension Cable
Product Features
Five mechanical housing designs are available, allowing customers to select a configuration based on interface access frequency, enclosure design, and appearance requirements.
The panel side uses an HDMI female receptacle, while the internal cable terminates in an HDMI male plug, providing a straightforward method of extending an internal HDMI interface to an equipment panel.
Each model is available in:
0.3M / 0.5M / 1M
The three standard cable lengths accommodate different distances between internal hardware and the external equipment panel.
Unlike a conventional inline HDMI extension cable, the product is designed for panel mounting and provides a dedicated mechanical interface on the equipment enclosure.
Product Breakdown
Why Is This Product Needed ?
Standard HDMI cables are primarily designed for device-to-device connections, but industrial equipment often requires additional interface integration.
Internal motherboard HDMI ports may be difficult to access after equipment assembly. Opening an enclosure every time a display is connected can also increase maintenance effort.
Conventional HDMI extension cables do not provide a dedicated panel-mount structure, and exposed interfaces may require additional protection in industrial environments.
Different equipment may also require different protective-cover mechanisms.
The Waterproof HDMI Panel Mount Extension Cable combines:
HDMI extension + panel mounting + interface protection + multiple cable lengths in one integrated product family.
Typical Applications
◆ Simplified Equipment Maintenance
The panel-mounted HDMI extension structure reduces the need to open equipment enclosures during routine display connection, maintenance, or system configuration.
◆ Reduced Stress on Internal HDMI Ports
External HDMI cables connect to a panel-mounted receptacle, allowing part of the mechanical load from insertion, removal, and cable movement to be supported by the enclosure rather than directly by the internal motherboard connector.
◆ Multiple Interface Access Methods
Screw-cap, hinged-cover, and capless configurations support different interface-access requirements, allowing manufacturers to select the most appropriate mechanical design.
◆ Supports Modular Equipment Design
Equipment manufacturers can standardize around an HDMI female-to-male extension concept while selecting different covers, colors, and cable lengths for different product families.

Product FAQ
How Many Main Configurations Are Available ?
The product family includes five primary mechanical configurations:
- Knurled screw cap
- Straight-ribbed screw cap
- Scalloped screw cap
- Hinged flip cover
- Capless
Each configuration is available in 0.3M, 0.5M, and 1M lengths.
Is This an HDMI Female-to-Male Cable ?
Yes.
The panel side uses an HDMI female receptacle, while the cable end uses an HDMI male plug.
It is designed to extend an internal HDMI connection to an external equipment panel.
What Are the Main Differences Between the Five Models ?
The primary difference is the protective structure around the panel-mounted HDMI female receptacle.
Products 1–3 use three different screw-cap designs, Product 4 uses a hinged flip cover, and Product 5 is capless.
All use an HDMI female-to-male extension configuration.
Can Other Cable Lengths Be Customized ?
Alternative cable lengths can be evaluated for OEM projects.
Because HDMI carries high-speed digital signals, complete-channel performance should be verified when cable length is increased.
How Should I Choose Between Screw Cap and Flip Cover ?
Screw-cap versions are suitable for interfaces that remain closed most of the time and are accessed mainly during maintenance.
Hinged versions are convenient for frequently accessed display or test interfaces.
