B&B USB TO USB 2 PORT ISOLATOR / HUB - 4KV, RUGGED

The B&B USB to USB isolator hub series delivers heavy‑duty electrical isolation with robust industrial performance. Available as the UHR401 (1‑port) and UHR402 (2‑port) configurations, these devices are engineered to withstand the harsh realities of automated environments, laboratories, and machine control setups. With 4 kV isolation, they act as a shield between your USB hosts and peripherals, dramatically reducing ground loops, surge effects, and EMI that can corrupt data or damage expensive equipment. Built around B&B’s trusted high‑retention USB connectors, the isolators are designed to resist vibration, dust, and repeated mating cycles while keeping signal integrity at the forefront. In short, these rugged USB isolators provide reliable, plug‑and‑play protection for critical systems where data integrity and equipment safety matter most.

Designed for enterprise and industrial deployments, the UHR401 and UHR402 balance protection with ease of use. The 4 kV isolation creates a safe electrical boundary that isolates USB devices from potentially noisy or misgrounded equipment, enabling stable communications even in environments with significant electrical noise or grounding differences. The rugged enclosure and EMC‑conscious design ensure consistent performance across temperature ranges, mechanical shocks, and demanding installation scenarios. If you need a USB hub that not only expands connectivity but also fortifies your system against ground loops and transient spikes, these isolators are built to perform while requiring minimal setup and maintenance.

What sets the UHR401 and UHR402 apart is their combination of isolation, reliability, and industrial suitability. Whether you’re equipping a factory floor, lab bench, or field installation, these devices provide a compact, resilient solution that integrates seamlessly with standard USB hosts and devices. The emphasis on high retention connectors minimizes the risk of unplugging under vibration and ensures long‑term durability in rugged environments. Pair one with a single USB device or deploy two downstream ports to support multiple peripherals—either way, you’ll experience safer data transfer and less electrical interference compromising your operations.

• 4 kV isolation between host and device to prevent dangerous ground loops, reduce noise, and protect sensitive equipment while preserving data integrity during USB communication.
• Rugged, industrial construction with EMI‑shielded enclosure and durable connectors designed to endure vibration, dust, and harsh environments typical of manufacturing, automation, and test benches.
• 1‑port (UHR401) and 2‑port (UHR402) variants offer flexible expansion while maintaining the same rugged isolation performance and high retention USB interfaces for secure connections.
• High retention USB connectors resist accidental disconnections in demanding installations, ensuring stable operation even in mobile or mounted installations.
• Plug‑and‑play USB 2.0 compatibility with standard hosts and devices, enabling quick deployment without drivers or complex configuration while delivering reliable isolation and data protection.

how to install [product]

• Step 1: Power down the host system and any connected devices before installation to minimize risk of electrical shock or data disruption.
• Step 2: Identify the upstream (host) USB port on the isolator and connect it to your computer, controller, or USB host using a standard USB cable. Ensure the orientation aligns with the device’s labeling.
• Step 3: Connect your downstream USB devices to the isolator’s ports. If you are using the 2‑port variant, distribute devices across both ports as needed to balance load and signal integrity.
• Step 4: Mount or secure the isolator in a suitable location, away from high‑vibration sources and excessive heat. Route cables to minimize bending, kinking, or interference with moving parts.
• Step 5: Power up the system and verify that all connected USB devices enumerate correctly. If a device is not detected, reseat the connections and check for any EMI sources nearby that could affect performance.

Frequently asked questions

• What is USB isolation and why is 4 kV important? USB isolation separates the electrical circuits of the host and downstream devices, protecting equipment from ground loops, surges, and EMI. A 4 kV isolation rating provides a strong safety margin for industrial environments and helps maintain reliable data transfer even in electrically noisy systems.
• How many ports do UHR401 and UHR402 provide? The UHR401 offers a single downstream USB port, while the UHR402 provides two downstream USB ports, allowing you to connect multiple peripherals through a rugged, isolated hub.
• Is this USB isolator compatible with USB 3.0 or USB‑C devices? The device is designed for USB 2.0 interfaces. For USB 3.0 or USB‑C requirements, verify compatibility with the exact model and consider higher‑speed isolators if needed.
• Where is this product typically used? It is well suited for manufacturing lines, automation systems, robotics, test benches, and other environments where ground loops, EMI, and transient disturbances pose a risk to data integrity or equipment safety.
• Do I need drivers to use the UHR401/UHR402? No additional drivers are required. These isolators operate as standard USB devices, providing plug‑and‑play functionality with compatible hosts and peripherals.
