The USB 3.0 Industrial Waterproof Panel Extension Cable series is designed to extend an internal USB 3.0 interface to the external panel of a control cabinet, industrial enclosure, or equipment chassis.

The basic connection architecture is:

P1: Panel-mount USB 3.0 Type-A female
P2: USB 3.0 Type-A male

This configuration allows the USB port of an industrial PC, embedded computer, controller, test instrument, or other internal device to be extended to an accessible equipment panel without modifying the original USB interface.

Three primary configurations are available:

Product 1: Rear-nut locking + tethered screw cap + Black / White / Blue / Yellow

Product 2: 20.8 panel cutout + external thread + tethered screw cap

Product 3: Rear-nut locking + thick-panel mounting + capless design

All three products are available in eight standard cable lengths:

0.1M / 0.3M / 0.5M / 1M / 1.5M / 2M / 3M / 4M

The series is suitable for industrial equipment OEM projects, control cabinets, industrial PCs, HMI systems, test instruments, machine vision, and R&D equipment.

Type 1:

USB 3.0 Rear-Nut Waterproof Extension Cable

Product 1 uses a rear-nut panel locking structure.

P1 is a panel-mount USB 3.0 Type-A female interface with a tethered screw-on protective cap, while P2 is a USB 3.0 Type-A male plug.

The connector body passes through the equipment panel and is secured by a retaining nut from the rear.

The tether keeps the protective cap attached to the connector when the USB port is opened, reducing the possibility of losing the cap during equipment maintenance.

Four colors are available:Black / White / Blue / Yellow

Eight cable lengths are offered:0.1M / 0.3M / 0.5M / 1M / 1.5M / 2M / 3M / 4M

Type 2

20.8 Cutout USB 3.0 Threaded Panel Extension Cable

Product 2 uses a 20.8 panel cutout structure.

The front side features a USB 3.0 Type-A female interface with an externally threaded housing and tethered screw cap. The rear cable terminates in a USB 3.0 Type-A male plug.

The 20.8 cutout configuration is suitable for equipment designed around the corresponding round panel opening.

Standard lengths:

0.1M / 0.3M / 0.5M / 1M / 1.5M / 2M / 3M / 4M

Before machining the equipment panel, the actual cutout tolerance, thread specification, and supported panel thickness should be checked against the corresponding engineering drawing.

Type 3:

USB 3.0 Thick-Panel Rear-Nut Extension Cable

Product 3 uses a round panel USB 3.0 female + rear-nut locking + capless structure.This configuration is designed particularly for equipment requiring thick-panel installation.

Unlike Products 1 and 2, Product 3 does not use a separate protective cap, leaving the USB female port directly accessible.

This design is suitable for:

Permanently connected USB devices
Frequent USB access
Protected installation areas
Equipment with an existing outer protective enclosure
Thick-panel enclosures and equipment chassis

Available lengths:0.1M / 0.3M / 0.5M / 1M / 1.5M / 2M / 3M / 4M

Product Features

USB 3.0 Type-A Female-to-Male Extension

All three products use a USB 3.0 Type-A panel female to USB 3.0 Type-A male extension architecture for integration with compatible USB-A equipment.

Eight Standard Cable Lengths

Eight standard cable lengths are available:

0.1M / 0.3M / 0.5M / 1M / 1.5M / 2M / 3M / 4M

Short versions support compact internal layouts, while longer versions provide additional routing flexibility for larger equipment.

Multiple Panel Mounting Structures

Rear-nut, 20.8 cutout threaded, and thick-panel configurations provide multiple installation options for different enclosure designs.

Protected and Open-Port Options

Products 1 and 2 use tethered screw caps, while Product 3 uses an open capless structure.

This allows the configuration to be selected according to access frequency, installation location, and overall equipment protection design.

Product Breakdown

Why Is This Product Needed ?

Many industrial devices already contain USB ports, but these ports are often located inside an enclosure and are inconvenient for daily operation.

Routing an ordinary USB extension cable through an enclosure opening may result in an unsecured interface, cable pulling, disorganized internal wiring, inconvenient maintenance, and limited port protection.

The USB 3.0 Industrial Waterproof Panel Extension Cable relocates the internal USB connection to a fixed panel interface.

It therefore addresses more than simple USB extension. It supports:

panel mounting + external access + internal cable routing + interface protection + OEM equipment integration.

Typical Applications

Industrial Automation and Control Cabinets

Industrial PCs and Embedded Systems

HMI and Industrial Display Equipment

Core Performance Advantages

◆ Reduced Mechanical Load on Internal USB Ports

External USB insertion and removal occur at the panel connector, reducing repeated direct handling of the internal computer or controller USB port.

◆ Improved Maintenance Efficiency

Compatible USB devices, service tools, or storage devices can be connected from outside the enclosure without repeatedly opening the equipment.

◆ Improved Internal Cable Management

Cable lengths from 0.1M to 4M allow the assembly to better match internal routing distances and reduce unnecessary cable accumulation.

◆ Supports OEM Interface Standardization

OEM manufacturers can standardize the external USB interface location while retaining flexibility in the internal computer or controller arrangement.

How to Select the Right Version ?

For rear-nut mounting + screw-cap protection + four color options:

→ Product 1

For equipment designed around a 20.8 panel cutout with an externally threaded protective cap:

→ Product 2

For thicker equipment panels, continuously connected USB devices, or quick-access applications where a separate cap is unnecessary:

→ Product 3

After selecting the mechanical structure, choose: 0.1M / 0.3M / 0.5M / 1M / 1.5M / 2M / 3M / 4M according to the internal routing distance.

For high-bandwidth USB 3.0 applications, longer configurations should be validated with the actual host, peripheral, and cable assembly.

Frequently Asked Questions

Product FAQ

What Are the Main Differences Between the Three USB Extension Cables ?

The main differences are the panel mounting structure and interface protection design.

Product 1 uses rear-nut locking with a tethered screw cap and is available in Black, White, Blue, and Yellow. Product 2 uses a 20.8 cutout with an externally threaded tethered cap. Product 3 uses a rear-nut structure for thick-panel installation without a separate protective cover.

All three use a USB 3.0 Type-A female-to-Type-A male extension architecture.

What Cable Lengths Are Available ?

All three products are available in eight standard lengths:

0.1M / 0.3M / 0.5M / 1M / 1.5M / 2M / 3M / 4M

What Does 20.8 Mean ?

According to the supplied product information, Product 2 uses a 20.8 panel cutout.

The 20.8 designation describes the supplied panel opening information and should not automatically be interpreted as the overall connector diameter or thread specification.

Dimensions and tolerances should be confirmed against the engineering drawing before volume panel machining.

What Is the Purpose of the Tethered Screw Cap ?

The tethered screw cap provides physical coverage for the USB interface when it is not in use, while the tether keeps the cap attached to the connector body.

Specific water- and dust-protection ratings should be based on test data for the corresponding configuration.

Are OEM, Wholesale, and Manufacturer Customization Services Available ?

Yes.

The series is suitable for wholesale USB 3.0 waterproof extension cables, custom panel USB connectors, industrial USB connector manufacturer projects, OEM USB panel extension cables, and custom USB cable assemblies.

Before volume production, confirm:

Drawing → Panel cutout → USB interface → Cable length → Color → Data performance → Sample.
