Industrial Ethernet switch for embedded systems

The Brainboxes SW-105 is a five-port unmanaged switch built for industrial and embedded deployments. Galvanic isolation on every port protects connected equipment from ground loops and voltage spikes. It operates across a -40 °C to +80 °C temperature range, suiting harsh environments such as factory floors or outdoor enclosures.

Fast Ethernet limits and power flexibility

Each port runs at 10/100 Mbps, so throughput tops out at Fast Ethernet speeds rather than Gigabit. The switch accepts dual redundant power inputs across a wide voltage range, including 24 V industrial supplies or USB sources. Power consumption adjusts automatically based on link status, and no software configuration is required.

Compact plug-in module with removable terminals

The unit measures 0.8 in high, 3.7 in wide and 3.5 in deep, weighing approximately 2.40 oz. A removable power terminal with numbered pins simplifies wiring and maintenance in tight cabinets. The plug-in form factor allows direct integration into custom panels or DIN-rail carriers. Manufactured in the United Kingdom, it carries RoHS and WEEE certifications.

Questions about this item

Which power option suits my setup, USB or 24 V?

The switch accepts both a USB source and a 24 V supply through its dual redundant inputs, so you can power it from a PC port or the factory floor.

What does 10/100 Mbps mean for actual throughput?

Each of the five ports negotiates at 10 or 100 Mbps full duplex, giving up to 100 Mbps per connection in a real machine.

How does the Fast Ethernet interface limit my network speed?

The 10/100Base-T ports cap each link at 100 Mbps, so gigabit devices will fall back to Fast Ethernet rates.
