Industrial metal USB hub with four ports and dual-host switch

LORDWORLD

LORDWORLD Industrial USB Hub 4-Port Dual-Host Switchable

SKU CH-KDXN-9M44P

A four-port USB hub with dual-host switching lets two computers share peripherals, while industrial-grade protection circuits and a rugged metal enclosure guard against surges.

  • Stable 4-port concurrency via MTT hub chip
  • Per-port ESD protection guards against surge damage
  • Over-voltage protection blocks harmful high-voltage input
  • Comprehensive safety circuits include over-current and thermal limits
  • Rugged metal enclosure with mounting holes for secure install

Industrial USB Hub for Dual-Host Switching

The LORDWORLD Industrial USB Hub provides four extended USB ports that can be switched between two host inputs. It is built for industrial environments where multiple computers or controllers need shared access to the same peripheral set without replugging cables. The rugged metal enclosure with mounting holes supports fixed installation on machinery, panels or DIN-rail setups.

Thermal and Electrical Protection Features

The hub integrates multiple protection circuits including over-voltage, over-current, short-circuit, over-temperature, reverse-current and under-voltage lock-out. Each port carries 8KV ESD protection and filtering to prevent surge damage and data loss during hot-plug events. The industrial-grade MTT hub chip manages four concurrent connections with stable throughput while the metal case passively dissipates heat in continuous operation.

Upgrade from Basic Hubs Lacking Host Switching

This unit replaces standard USB hubs that offer only a single upstream connection and no hardware protection. The jump is worth it when two hosts must alternately control the same four devices — such as switching a sensor array between a PLC and a maintenance laptop — or when industrial ESD and voltage transients threaten unprotected consumer hubs. It is not suited for applications requiring more than four downstream ports or automated software-controlled switching.

이 상품에 대한 질문

How do I mount the LORDWORLD hub securely, and which orientation do installers often forget?

Use the pre-drilled mounting holes on the metal case to bolt the hub to a DIN rail, panel or chassis; the step most missed is leaving clearance around the case for heat dissipation so the over-temperature protection does not trip under sustained load.

What component will eventually need replacement after years of industrial ESD events?

The 8 kV ESD protection diodes on each USB port absorb repeated strikes and degrade over time; when surge immunity drops the hub still passes data but no longer shields connected devices, so plan to swap the unit after heavy static exposure.

Which protection limit activates first when all four ports draw maximum current continuously?

The over-current circuit monitors total bus current and will trip before the over-temperature or under-voltage lock-out circuits, cutting power to the downstream ports until the load is reduced and the hub resets.
