Belden RS2-5TX FX Industrial Ethernet Managed Switch

The Hirschmann RS2-5TX/FX Rail Switch (Belden) is a compact DIN-rail mounted industrial Ethernet switch designed for rugged factory environments, providing reliable, plug‑and‑play connectivity on the shop floor. It combines four 10/100BASE‑TX RJ‑45 copper ports with one 100BASE‑FX fiber port (MM fiber) to support mixed copper/fiber networks, and uses store‑and‑forward switching with auto‑negotiation and auto‑crossing (MDI/MDI‑X) for straightforward deployment. Powered from 9.6–32 V DC (typical 24 V), it draws up to 100 mA at 24 V and up to 2.2 W of power, weighs about 113 g, and operates from 0 °C to 60 °C, making it suitable for connecting PLCs, sensors and other industrial devices in automation environments. The model is identified by part number 943732‑103, distinguishing this RS2‑5TX/FX configuration within Belden’s Hirschmann rail‑switch lineup.
