10/100TX-FX Single Fiber Industrial Media Converter | 1-RJ45 Ethernet Port, 1-ST Fiber Port

Description Technical Specification Key Features Resources & Downloads Applications

The VERSITRON MF7275-2SFA Industrial Media Converter is engineered to deliver high-performance copper-to-fiber conversion in harsh industrial environments. Featuring one 10/100Mbps RJ-45 Ethernet port and one 100Mbps fiber port (ST connector), this media converter ensures long-distance, noise-resistant network communication.

With store-and-forward architecture and non-blocking switching, the MF7275-2SFA optimizes data transmission while minimizing packet loss. Its auto-negotiation and auto MDI/MDI-X crossover support allow for easy plug-and-play operation, adapting seamlessly to different network devices.

Built for industrial reliability, this media converter supports dual DC power inputs (9-52V) for redundancy and low power consumption (4W full load). It boasts 4KV surge protection, IP44 corrosion-resistant casing, and extended temperature tolerance (-40°C to 80°C), ensuring maximum durability in extreme conditions. The device is DIN rail mountable, making it easy to install in tight control panels or enclosures.

The MF7275-2SFA is typically used in pairs, working alongside the MF7275-2SFB to enable single-fiber bi-directional communication for long-distance, high-reliability networking.
