Couldn't load pickup availability
The Industrial grade USB HUB is a powerful USB 3.2 port expander designed to solve the problem of limited USB ports while adding the unique ability to switch between two host computers.
This dual host USB switch feature lets you connect and access the same USB devices from two different computers with a simple toggle, eliminating the need for multiple keyboards, mice, or other peripherals on your desk.
The device uses industrial-grade HUB chip with MTT (Multi-Transaction Translator) technology to ensure stable and smooth connections even when all four ports are being used simultaneously. With data transfer speeds up to 5Gbps, this hub is perfect for connecting high-performance devices like external hard drives, cameras, and other USB peripherals.
What makes this industrial USB hub stand out is its comprehensive protection system designed for demanding environments. The protected USB hub includes multiple safeguards such as over-voltage protection, over-current protection (with 1.2A maximum output per port), short circuit protection, over-temperature protection, reverse current protection, and 8KV ESD protection to prevent damage to both the hub and connected devices.
The rugged metal casing with mounting holes makes installation easy in industrial settings, while the wide operating temperature range (-10°C to 85°C) ensures reliable performance in various conditions. Whether you're setting up a workstation that needs to connect to multiple computers, building an industrial control system, or simply need more USB ports with enhanced protection, this industrial-grade USB hub provides a durable and versatile solution.
