SFN Unmanaged Ethernet Switch

Phoenix Contact's SFN (Standard Function Narrow) unmanaged Ethernet switches provide low-cost, fully industrially hardened, entry-level switch functions with five or eight ports in a narrow housing width. These include a complete range of 100 Mbps glass-fiber configurations to support one or two ports with SC or ST style connectors.

Each SFN switch includes the unique ability to add optional security frames that can be used to block unused RJ45 ports or lock in existing cables. This physical Layer 1 security restricts network access by unauthorized personnel, yet is simple enough for plant floor personnel to implement.

The SFN series also includes new extended temperature range switches for 10/100 Mbps applications and 802.3z gigabit switches for applications requiring intense data or the anticipation of future network expansion.
