Rugged multi-port connectivity options tailored for marine terminals, industrial automation, and data acquisition hubs.
As Bangladesh's primary commercial hub and largest seaport, Chattogram (Chittagong) represents the economic engine of the nation, managing over 90% of Bangladesh’s import and export trade. The expansion of the Chittagong Port Authority (CPA) terminals, alongside rapid development inside the Chittagong Export Processing Zone (CEPZ) and the Karnaphuli EPZ (KEPZ), has catalyzed an urgent technological pivot. Modern manufacturing, heavy shipping, textile automation, and container terminal management are transitioning from manual systems to IoT-enabled Smart Industrial Networks.
This industrial transition requires highly stable, rugged data connectivity devices. Rack-mounted USB hubs serve as the nervous system for digital telemetry in Chittagong, powering high-speed data acquisition from PLC (Programmable Logic Controller) boxes, barcode scanning arrays in logistics docks, automated textile looms, and maritime monitoring systems. Our products are specifically engineered to withstand Chattogram's typical coastal environmental factors—high salinity, high humidity, and electrical noise from heavy crane machinery.
How Shenzhen RF-Core Charger Co., Ltd. is engineering connectivity for future-proof industrial grids.
Providing up to 15kV Air and 8kV Contact ESD protection (IEC 61000-4-2 standard) alongside 350W transient surge mitigation. This shields host controllers from current back-feed and inductive spikes caused by large port motors.
Integrating dual-host upstream configurations that allow real-time failover switching. If a primary port server fails in a Chittagong marine telemetry setup, the secondary server instantly assumes control of all connected USB arrays.
Aluminum alloy and SPCC steel enclosures engineered for passive ventilation, supporting stable operations from -40°C to +85°C. Powered by smart chips that dynamically distribute power to prevent over-current and thermal build-up.

Robust architecture designed to streamline large-scale digital setups across major industries.
In cargo depots, maritime systems interface with dynamic sensor networks. Rack-mounted USB hubs with ESD protection link main servers to multiple GPS receivers, RFID scanners, container scale controllers, and rugged thermal printers. This architecture prevents system resets and data loss during constant hot-swapping.
Textile mills inside CEPZ utilize automated cutting machines and computerized embroidery systems. Our DIN-Rail and Rack-mount USB hubs serve as the communication bridge, transferring stitching files and data packets from control desks to multiple target machines without dropouts, even amidst high electromagnetic interference.
Chittagong’s local telecommunication server rooms employ 19-inch racks where multiple console terminals, modems, and diagnostic boards must communicate with centralized server units. Our high-port density hubs are engineered to mount perfectly into standard 1U/2U configurations, simplifying cable management.
Shenzhen RF-Core Charger Co., Ltd. is a high-tech enterprise integrating research and development, manufacturing, and global sales, specializing in advanced charging and connectivity solutions for modern digital devices. Operating from our advanced manufacturing base in Shenzhen, we bring the efficiency of Factory 4.0 direct to Chittagong bulk buyers.
Our facility leverages automated SMT (Surface Mount Technology) assembly lines, AOI (Automated Optical Inspection) scanners, and custom aging chambers to verify every industrial hub under high-stress loads. We specialize in large-scale centralized charging and data solutions, offering 10-100 port high-density hubs, fast charging systems, and rugged industrial controllers.
We provide one-stop OEM/ODM solutions. Our engineering team handles everything from custom PCB layout design and firmware customization (for managed USB hubs) to final industrial enclosure design and prototyping. This rapid customization cycle allows our Chittagong industrial buyers to procure hubs tailored to their custom mounting requirements, port layouts, or specific input voltages (e.g., 9-36V DC inputs for marine applications).
Importing industrial-grade hardware to Chittagong requires seamless shipping channels, clear customs handling, and compliant documentation. RF-Core ensures reliable export procedures through direct sea routes to Chittagong Port (CPA) or rapid air freight to Shah Amanat International Airport. We provide complete commercial documentation packs including clean Bills of Lading, Certificates of Origin, CE/FCC conformity reports, and customs-harmonized tariff classifications (HS Codes) to prevent clearance delays.
Furthermore, our customer support provides specialized setup guidance for industrial installers in Bangladesh. Whether it's choosing between a wide-voltage DC terminal block connector (9V-36V) for marine vessel power supplies or standard AC-DC adapters for CEPZ manufacturing units, our engineers offer direct assistance to ensure your hardware functions flawlessly from day one.

When selecting connectivity hardware for heavy-duty environments in Chittagong, standard retail hardware will fail prematurely due to dust, humidity, and heat. B2B procurement managers should evaluate the following structural specifications:
Key technical and logistics inquiries resolved by our technical engineering team.
Our industrial-grade USB hubs integrate transient voltage suppressors (TVS) and ESD protection chips that limit electrical surges (up to 15kV air and 8kV contact). When an electrical fault, lightning strike, or heavy industrial machinery startup creates a power surge, the TVS diodes divert the excess current to ground within nanoseconds. This prevents physical damage to the costly host PC motherboard and connected peripherals.
Standard model shipments take 7–15 working days. For OEM/ODM designs requiring custom PCB layout or metal fabrication, development and sample production take 3–4 weeks, followed by 15–20 days for mass production. Shipping from Shenzhen to Chittagong Port (CPA) via sea route generally takes 12–18 days, while air shipping to CGP airport takes 3–5 days.
Yes. Our industrial-grade models feature rugged metal enclosures (IP30/IP40 rated) and utilize components qualified for extreme temperature ranges (-40°C to +85°C). The passive cooling structure is designed without open vent slots in critical locations to minimize dust deposition and prevent humidity buildup on the circuit board.
Managed USB hubs include a controller interface allowing operators to turn individual ports on or off via command-line interface (CLI) or custom software APIs. This is useful for automated testing setups, resetting frozen devices remotely without physically unplugging them, and conserving power in multi-device installations.
Yes, many models in our lineup feature mounting hardware configurations that support DIN-rail clips (typically 35mm), wall mounting flanges, and standard 19-inch 1U/2U rack ears. Please specify your required mounting option when placing an inquiry so we can include the correct mounting kits.
All RF-Core industrial connectivity products are manufactured under strict ISO9001 guidelines and carry international certifications including CE, FCC, RoHS, and CCC. These certifications verify electrical safety, EMI/EMC compliance, and environmental standards, facilitating smooth customs clearance at Bangladesh entry points.
