The USB 3.0 Industrial Waterproof Panel Connector series is designed to integrate a USB 3.0 Type-A interface into industrial equipment, control cabinets, enclosures, and instrument panels.

Unlike a conventional USB adapter, the series focuses on three key requirements:

fixed USB mounting, external accessibility, and equipment-panel integration.

Five mechanical configurations are available:

Product 1 – USB 3.0 round panel female, capless

Rear-nut mounting with Black, White, Blue, and Yellow options.

Product 2 – USB 3.0 round panel female with hinged cover

Rear-nut locking with an integrated protective cover.

Product 3 – USB 3.0 waterproof panel female with tethered screw cap

Single-hole rear-nut mounting.

Product 4 – USB 3.0 waterproof panel female with externally threaded tethered cap

20.8 mm class panel cutout with front-nut locking.

Product 5 – USB 3.0 waterproof panel female with tethered screw cap

Single-hole mounting for industrial and outdoor equipment integration.

Each product is available in two rear-interface versions:

Feedthrough
Solder Pin

This allows equipment manufacturers to select a configuration according to internal cabling, PCB architecture, and maintenance requirements.

Item	Product 1	Product 2	Product 3	Product 4	Product 5
Interface	USB 3.0 Female	USB 3.0 Female	USB 3.0 Female	USB 3.0 Female	USB 3.0 Female
Cover	Capless	Hinged Cover	Tethered Cap	Threaded Tethered Cap	Tethered Cap

Anti-Rotation	3.30 Slot	3.30 Slot	D-Flat	D-Flat	D-Flat

Type 1:

USB 3.0 Capless Rear-Nut Panel Connector

Product 1 uses a round rear-nut mounting structure with a USB 3.0 Type-A female interface and no separate protective cover.

According to the supplied panel drawing:

Main circular cutout: Ø22.50 mm
Overall cutout height: 24.00 mm
Top locating slot width: 3.30 mm

The locating slot provides anti-rotation positioning and helps maintain a defined connector orientation during installation.

Type 2

USB 3.0 Hinged-Cover Rear-Nut Panel Connector

Product 2 uses rear-nut locking with an integrated hinged cover over the USB female interface.

Unlike a removable screw cap, the hinged cover remains attached to the connector body and can be opened for USB access and closed again after use.

According to the supplied drawing:

Main circular cutout: Ø22.50 mm
Overall cutout height: 24.00 mm
Top locating slot width: 3.30 mm

Products 1 and 2 therefore use a similar panel cutout concept while providing different external protection structures.

Type 3:

USB 3.0 Rear-Nut Tethered-Cap Panel Connector

Product 3 uses single-hole rear-nut locking with a tethered screw-on protective cap.

When closed, the cap covers the USB interface. When opened, the tether keeps the cap attached to the connector body.

The panel opening incorporates an anti-rotation flat.

According to the supplied drawing:

Arc diameter: Ø20.70 ±0.10 mm
Anti-rotation flat position: 9.75 ±0.05 mm
Right-side reference dimension: 10.35 mm

The D-shaped anti-rotation structure helps prevent connector rotation and maintains USB interface orientation.

Type 4:

M20.8 USB 3.0 Front-Nut Threaded Panel Connector

Product 4 uses a 20.8 mm class cutout + front-nut locking + externally threaded tethered screw cap structure.

This configuration is suitable where the primary locking operation needs to be accessible from the front of the equipment panel.

According to the supplied drawing:

Arc diameter: Ø20.8 mm
D-shaped cutout width: 19.40 mm

The panel opening is not a simple circular hole. It includes an anti-rotation flat and should therefore be machined according to the complete D-shaped profile.

Type 5:

USB 3.0 Single-Hole Tethered-Cap Panel Connector

Product 5 uses a USB 3.0 panel female interface with a tethered screw cap for industrial and outdoor equipment integration.

According to the fifth supplied drawing:

Arc diameter: Ø20.8 mm
D-shaped cutout width: 19.40 mm

The anti-rotation flat helps maintain connector orientation.

For outdoor applications, actual environmental protection depends on installation condition, cap status, sealing design, and verified protection testing.

Product Features

Five Mechanical Configurations

The series combines capless, hinged-cover, tethered-cap, externally threaded, front-nut, and rear-nut structures for different equipment designs.

Feedthrough and Solder-Pin Versions

Each configuration is available in feedthrough and solder-pin versions for cable-based or PCB-integrated systems.

Anti-Rotation Panel Cutouts

Locating slots or D-shaped flats provide mechanical anti-rotation positioning.

Multiple Interface Protection Options

Capless, hinged-cover, and screw-cap configurations support different access frequencies and equipment environments.

Product Breakdown

Why Is This Product Needed ?

Industrial PCs, embedded computers, controllers, and test systems may already contain USB interfaces, but the original ports are not always located where operators can conveniently access them.

A loose USB cable routed through an enclosure opening does not provide a fixed interface and may create cable-management and maintenance problems.

A panel connector creates a standardized connection architecture:

External device → Fixed USB panel interface → Internal cable or PCB → Host

This retains the convenience of USB while integrating the interface into the mechanical design of the equipment.

It converts a conventional RJ45 interface into a fixed panel-mounted network access point suitable for industrial equipment integration.

Typical Applications

Industrial Automation and Control Cabinets

Used for USB configuration, programming, and maintenance access in PLC, robotics, and industrial control systems.

Industrial PCs and Embedded Systems

Relocates internal USB connections to an accessible front or rear equipment panel.

HMI and Industrial Display Equipment

Suitable for USB data interfaces on touchscreens, HMI terminals, and industrial display systems.

Core Performance Advantages

Improved Service Accessibility

The USB connection can be accessed externally without repeatedly opening the equipment enclosure.

Reduced Internal Port Stress

External mating occurs at the panel connector, reducing direct handling of internal host or PCB interfaces.

Supports Modular Equipment Design

The panel interface can remain mechanically independent from internal hosts, PCBs, or cable assemblies.

Frequently Asked Questions

Product FAQ

What Are the Main Differences Between the Five Products ?

The primary differences are panel cutout geometry, nut position, and protective-cover structure.

Are Both Feedthrough and Solder-Pin Versions Available ?

Yes. According to the supplied product information, all five configurations are available in both Feedthrough and Solder Pin versions.

How Do I Choose Between Feedthrough and Solder Pin ?

Choose Feedthrough for standard internal USB cable connections and Solder Pin for PCB or fixed internal circuit integration.

What Should Be Considered for the Solder-Pin Version ?

In addition to pinout, USB 3.0 solder-pin designs should consider high-speed differential routing, impedance, return paths, shielding, and PCB layout around the connector.

Are Custom, Wholesale, and OEM Services Available ?

OEM projects can support custom waterproof USB connectors, wholesale panel USB connectors, industrial USB connector manufacturing, OEM USB panel connectors, and custom solder-pin USB assemblies.

A recommended production process is:

Drawing confirmation → Cutout confirmation → Feedthrough/Solder-Pin selection → Sample → USB data testing → Volume production.
