  • Full design integration supported with schematic, DWF, PCB footprint and 3D model downloads

Compact industrial Ethernet switch

The Brainboxes PE-505 is a five-port 10/100 Mbps switch built for embedded and industrial designs. Its 55 x 55 x 10 mm footprint is smaller than a standard business card, allowing integration into space-constrained equipment. The unit operates reliably across a -40 °C to +85 °C temperature range. It targets engineers who need deterministic wired connectivity in harsh environments.

Design resources and LED flexibility

Comprehensive development resources include schematic, DWF file, PCB footprint and 3D model downloads to accelerate board layout. LEDs are visible in all orientations and can be routed to an outer casing using fibre optics or light pipes. Board-to-board and board-to-cable connection options support varied mechanical integration. These features reduce hardware bring-up time for OEM projects.

Five ports at 100 Mbps per port

The switch provides five 10/100 Mbps wired ports with a total switching capacity suited to modest industrial networks. It comfortably handles sensor clusters, PLC links and similar low-bandwidth traffic. The 100 Mbps per-port ceiling limits throughput for high-speed imaging or bulk data transfer. Designs requiring gigabit rates or more than five nodes will need a different platform.

Questions about this item

How do I maintain the PE-505 switch in a dusty industrial cabinet?

The PE-505 has no moving parts or filters; just keep the enclosure vents clear so ambient temperature stays within the -40 °C to +85 °C operating range.

What limits throughput when the PE-505 runs at full load continuously?

Each of the five ports tops out at 100 Mbps, so sustained traffic above that rate will queue at the port itself.

How much heat does the PE-505 add to a sealed enclosure running 24/7?

The fanless design dissipates heat through the 55 x 55 mm board, so the enclosure must handle the switch's waste heat without exceeding +85 °C ambient.
