Overview

The Westermo SandCat-3505-T5G-LV is a 5-port unmanaged industrial Gigabit Ethernet switch designed for robust performance in demanding industrial, maritime, and rail trackside applications. This switch features five 10/100/1000 RJ45 ports, providing high-speed connectivity for your network infrastructure. It supports dual 12-48 VDC power input with reverse-polarity protection, ensuring reliable operation even with fluctuating power sources. The SandCat-3000 series is built with industrial-grade components for exceptional Mean Time Between Failures (MTBF) and a long service life. Its purpose-built DIN-rail casing allows for easy installation in industrial control panels. Operating within a wide temperature range of -40 to +70°C (-40 to +158°F), this switch maintains performance without moving parts. The "tri-galvanic" isolation provides isolation between all ports, the power supply, and chassis screens, effectively preventing ground loop currents. With an IP21 rating, it is suitable for environments where condensed water may occur. The SandCat-3505-T5G-LV is transparent to all industrial Ethernet protocols and offers plug-and-play functionality, simplifying deployment. Features like support for 802.1Q long packets and broadcast storm protection enhance network stability. Port mirroring is included for simplified network diagnostics, allowing data flow monitoring with a network analyzer. DIP switches enable locking data rate and flow control on all five ports to prevent network issues. This switch meets stringent EMC, isolation, vibration, and shock standards, verified by Westermo and external test houses for heavy industrial, trackside, and maritime environments. The link fault forward function aids in creating resilient network structures by transferring media failure indications to connected ports. Manufacturer SKU: SandCat-3505-T5G-LV.
