Phoenix Contact FL SWITCH SF 16TX – 16-Port Unmanaged Industrial Ethernet Switch

The FL SWITCH SF 16TX (order no. 2832849) is a 16-port unmanaged industrial Ethernet switch built for the control cabinet. All 16 RJ45 ports auto-detect 10 or 100 Mbps with auto-negotiation and autocrossing, so any straight or crossover cable works without configuration. Unlike an office-grade switch, it runs on redundant 24V DC, carries a potential-free alarm relay for signaling supply faults, and mounts on a DIN rail in an IP20 aluminum housing rated to 55°C — a plug-and-play backbone for machine and plant networks.
