PCM-KW-646 is a USB 2.0 waterproof panel-mount cable developed for industrial equipment requiring an externally accessible USB interface. The waterproof USB Type-B female socket extends an internal USB connection to a control cabinet, equipment enclosure, dashboard, or operating panel, while the standard USB Type-A male connector connects directly to an internal industrial PC, host controller, or compatible USB host.
This architecture is particularly suitable for OEM equipment requiring a fixed maintenance, data-download, or debugging interface. Compared with routing a loose USB cable through an enclosure opening, the panel-mount structure creates a cleaner and more secure external connection point while reducing mechanical stress on internal wiring.
The standard 0.3m length is optimized for short-range connections between the panel interface and an internal host system. In control boxes, embedded computers, automation instruments, and compact cabinets, it reduces excess cable loops and helps create cleaner internal routing.
The short cable length also helps minimize interference with fans, power modules, PCBs, and moving mechanisms, making it suitable where the panel-mounted USB interface is located close to the internal host.
Core Advantages
As a milestone innovation in industrial interconnects from Premier Cable, the PCM-KW-646 delivers extreme protection in tight spaces. It solves the vulnerability of standard USB ports to oxidation and short circuits in wet or dusty sites, providing a vital perimeter barrier for smart hardware.
Reliable Connection
To guarantee uninterrupted data flow, this waterproof cable utilizes a tension-resistant locking mechanism. Once the USB-B end is mated with its protective cap/plug, it withstands high axial pulling forces. Inside, the fully-shielded structure eliminates crosstalk from nearby motors or inverters to ensure zero packet loss.
Installation Requirements
This item is custom-built for bulkhead enclosures and control panels. The female port requires a standard 20.8mm cutout diameter, adapting to various metal or plastic chassis thicknesses. The included hex locking nut and thick elastic washer allow technicians to achieve an airtight seal in seconds without soldering.

Product Features
|
◆ IP67 Waterproof USB-B Panel-Mount Female
The external interface uses a waterproof USB Type-B female receptacle designed for fixed panel installation on equipment enclosures, control boxes, or cabinets. When installed correctly with the required sealing gasket and locking hardware, the interface can provide IP67-rated protection under the specified operating condition, helping prevent dust, moisture, and external contaminants from entering the connection area. Compared with a conventional exposed USB-B port, this waterproof panel-mount design is better suited to industrial automation equipment, outdoor electronics, marine control systems, and industrial enclosures that may require periodic cleaning. It provides a practical solution for OEM equipment that needs permanent external USB access while maintaining improved environmental protection.

◆ Secure Threaded Panel-Mount Structure
The USB-B female connector uses a threaded panel-mount structure that is secured to the equipment panel with a locking nut and sealing gasket. Compared with snap-fit or simple press-fit designs, the threaded mounting system provides stronger mechanical retention and helps reduce the risk of connector loosening, rotation, or displacement caused by equipment vibration, repeated mating, or cable pulling. The 20.8mm panel cutout also simplifies standardized enclosure and sheet-metal design for OEM manufacturers, supporting more consistent installation during volume production. In industrial control cabinets, test instruments, and embedded systems, the fixed panel-mount architecture also helps isolate internal PCB or host USB connectors from external insertion and removal forces.

◆ USB 2.0 High-Speed Compatibility
Supports standard USB 2.0 High-Speed communication with a signaling rate of up to 480Mbps, making it suitable for industrial equipment configuration, log retrieval, software maintenance, printing communication, test-data transfer, and peripheral connectivity. The cable retains the familiar USB Type-A and Type-B interface architecture, allowing straightforward integration with existing industrial PCs, embedded hosts, and USB peripherals without redesigning the overall communication system. It can also support lower-speed USB 1.1 devices where system compatibility allows.

◆ 0.3m Compact Shielded Cable Construction
The standard 0.3m cable length is designed specifically for short internal connections between the panel-mounted USB-B receptacle and an internal USB host. Compared with general-purpose 1m or 2m extension cables, the compact 30cm design reduces excess cable loops, tangling, sharp bends, and unnecessary space consumption inside equipment enclosures. The cable also incorporates shielding around the USB D+/D− data lines to provide additional isolation from electromagnetic interference. This helps reduce the influence of EMI/RFI generated by motors, relays, switching power supplies, servo drives, and other industrial equipment. The combination of short routing distance and shielding makes the cable particularly suitable for internal USB interface extension in control cabinets, industrial PCs, and compact OEM systems.

Core Application Scenarios
Marine & Maritime Electronics
Suitable for ship wheelhouse consoles, onboard industrial computers, marine exploration equipment, surveying instruments, weather stations, hydrological monitoring terminals, and offshore data acquisition systems. PCM-KW-646 extends an internal USB host interface to an externally accessible panel, providing a fixed USB 2.0 connection for field data download, parameter configuration, diagnostics, log retrieval, and maintenance communication.
Marine, ocean-monitoring, and field-survey equipment may operate in environments exposed to high humidity, condensation, salt-laden air, dust, and occasional water splash. When correctly installed and sealed, the waterproof USB-B panel-mount receptacle provides IP67 protection, helping reduce the risk of moisture and contaminants entering the equipment through the USB interface area.
Industrial Automation Equipment
Suitable for USB data interface extension in CNC machines, PLC control cabinets, industrial PCs, automated production lines, robotic workstations, test equipment, and rugged outdoor control terminals. PCM-KW-646 extends an internal USB Type-A host connection to a waterproof USB Type-B female socket mounted on the cabinet, enclosure, or operating panel, allowing engineers to perform parameter configuration, software download, log retrieval, production data export, and equipment maintenance without opening the enclosure.

Frequently Asked Questions
Q1: Is the cutout size standard? What is the thread dimension?
A1: Yes, the standard panel cutout diameter for the female bulkhead is 20.8mm. The precision thread matches perfectly with most standard industrial waterproof enclosures or distribution panels.
Q2: Is the female connector waterproof on its own if left unmated without a cap?
A2: In an unmated state, a dedicated waterproof dust cap (sold separately or optionally equipped) must be screwed on tightly to maintain the full IP67 rating. Open ports expose internal slots.
Q3: Is the 0.3m length customizable? Do you offer longer versions?
A3: Yes. As a direct manufacturer, Premier Cable supports deeply customized ODM/OEM options for cable lengths, materials, and connector configurations. Contact our sales team for bulk requests.
