Product Summary
The SandCat-3505-T5G-LV is a 5-port unmanaged Ethernet switch in the SandCat-3000 series, engineered for robust performance in demanding industrial, maritime and trackside environments. It provides reliable Layer 1 connectivity with support for 802.1Q long packets and standard industrial Ethernet protocols. The unit accepts dual 12–48 VDC power input and uses industrial-grade components to deliver high MTBF and long service life. The tri-galvanic isolation ensures strong separation between all ports, the power supply and chassis screens, preventing ground loop currents. Operating temperature ranges from -40 to +70 °C and the IP21 protection allows installation where condensed water may occur.

Approvals and ruggedness
The product is tested to industry standards for EMC, isolation, vibration and shock and carries common approvals including CE, UL and DNV-GL level certifications suitable for heavy industrial, maritime and trackside installations.
