The primary function of this waterproof USB 2.0 extension cable is to extend an internal USB 2.0 interface to an external control panel while providing a closable protective structure for the exposed female receptacle.
In industrial control cabinets, automation equipment, and embedded computers, USB ports are often located inside the equipment or on the rear of the enclosure. Operators may need to remove the housing to perform firmware updates, retrieve data, or connect peripherals.
By installing a USB 2.0 panel mount extension cable, the USB interface can be positioned on the front or side of the equipment, enabling external data access, parameter configuration, equipment diagnostics, and maintenance operations.
Core Performance Advantages
The external USB port enables convenient data access, parameter configuration, and firmware updates without repeatedly opening the enclosure, simplifying maintenance and reducing exposure of internal components.
USB 2.0 supports routine industrial data communication, while the circular panel mount and multiple cable lengths reduce unnecessary adapters and cable slack, improving internal cable routing.
Available in four colors and eight cable lengths, offering 32 standard combinations to meet equipment design, port identification, and routing requirements while simplifying OEM bulk procurement and material management.
Products Specification
Why Is This Product Needed ?
Conventional USB extension cables often lack secure panel mounting and port protection, resulting in inconvenient access and dust accumulation.
This industrial USB 2.0 panel mount extension cable integrates data extension, secure mounting, and a self-closing protective cover, enabling convenient external USB access without relocating internal ports.
Available in four colors and eight cable lengths, it supports flexible routing, port protection, and easy maintenance in industrial control cabinets, outdoor equipment, and embedded systems.
Additionally, the four color options and eight cable lengths accommodate different interface identification, equipment layout, and cable management requirements.
Typical Applications
◆ Data Transmission Capability
The product uses USB 3.0 Type-A connectors and can connect compatible USB 3.0 devices as well as equipment using earlier USB standards.
USB 3.0 provides a nominal SuperSpeed signaling rate of 5Gbps, while actual file transfer speed depends on the host controller, storage device, protocol overhead, and cable signal integrity.
◆ Power Delivery Capability
The assembly provides a USB power connection path through its USB-A connectors and can be used with compatible peripherals powered by a USB host.
Available current depends on the host port's power capability, conductor gauge, cable length, and connector ratings.
This product should not be used as a USB-C Power Delivery fast-charging cable or treated as an independent power conversion device.
◆ Environmental Protection Capability
The panel-mounted connector features a protective cover that helps reduce direct exposure of the USB receptacle to dust and water droplets when the port is unused and the cover is properly closed.
The actual ingress protection rating depends on the sealing ring, housing fit, panel installation, and complete enclosure sealing design.
Eight Cable Length Options
Each color is available in the following eight cable lengths, providing a total of 32 color and length combinations.
Product Reliability
The threaded housing and retaining nut create a panel-mounting structure that helps reduce movement of the USB female receptacle relative to the equipment panel during routine connection and disconnection.
An appropriate tightening method should be selected according to the connector structure and panel material to avoid damage to the plastic housing or equipment panel.
The self-closing flip cover provides a physical barrier when the port is unused, reducing direct exposure to dust and external contaminants.
During long-term operation, the cover hinge, closing condition, and sealing areas should be inspected to prevent mechanical damage or accumulated debris from affecting protection.
Reliable USB 3.0 high-speed connectivity requires appropriate differential pair geometry, shielding continuity, and termination quality.
During equipment development and mass production, continuity, short-circuit, and actual USB data transmission tests should be performed according to the intended cable length, with particular attention to signal integrity in longer versions such as 3m and 4m.
Products Drawing
Product FAQ
What mounting hole size is required ?
According to the supplied installation drawing, the circular mounting hole diameter is 22.50mm, the upper locating notch width is 3.30mm, and the overall cutout height is 24.00mm.
Before installation, verify the equipment panel cutout dimensions, panel thickness, and available rear mounting clearance.
Does the self-closing flip cover provide complete waterproof protection ?
The self-closing flip cover provides protection when the USB port is not in use. However, achieving a specific IP rating requires verification of the product sealing structure, panel installation method, and actual test results.
When a USB device is inserted, the cover remains open, and the same level of waterproof protection should not be assumed.
Does the 4m version support USB 3.0 5Gbps transmission ?
The 4m version is an available cable length configuration. However, the USB 3.0 connector type alone does not guarantee 5Gbps operation with every device at this length.
Longer passive USB cables may introduce additional signal loss. Performance should therefore be verified using the actual cable construction, host, peripheral, and complete connection path.
For projects requiring reliable 5Gbps operation, practical equipment testing is recommended before confirming bulk procurement.
Does this product support USB-C Power Delivery fast charging ?
No. This product does not provide USB-C Power Delivery protocol negotiation. It is a passive USB-A male-to-female extension assembly primarily designed to extend USB data and corresponding power connections.
Actual power delivery capability depends on the host port, connector ratings, and cable specifications. It should not be used as an independent fast-charging converter.
Can the cable be customized for specific equipment requirements ?
Premier Cable can evaluate OEM customization options for cable length, housing color, connector configuration, and mounting structure based on customer-supplied equipment interfaces, panel cutout dimensions, and internal routing requirements.
Customers can provide the required cable length, equipment drawings, operating environment, and estimated purchasing quantity to help determine the appropriate product configuration.
