Phoenix Contact FL SWITCH SFN 4TX/FX ST, part number 2891453, is a robust Phoenix 4 Ports Industrial Switch with 4 TP RJ45 ports and 1 ST multi-mode fiber channel. Engineered for DIN rail mounting, it ensures secure installation inside control panels using screw terminal connections. The switch delivers 100 Mbps full duplex data transmission over a fiber length of up to 2000 meters with 50/125 μm fiberglass, offering seamless integration across large-scale industrial environments. Housed in a durable aluminum enclosure, it is rated for IP20 protection and withstands ambient operating temperatures from 0 °C to 60 °C. With a wide supply voltage range of 9–32V DC and extremely low typical current consumption of 140 mA, this model balances performance with energy efficiency. The device includes diagnostic LEDs to display power, link, and activity per port, helping technicians quickly assess network health.
