Belden MM3-2FXS2 2TX1 Programmable Logic Controller Module

Belden's Hirschmann MM3-2FXS2/2TX1 is a media module for MICE Switches (MS...), expanding an industrial Ethernet switch with two copper and two fiber ports. It provides two 100BASE-TX RJ-45 ports for copper Ethernet and two 100BASE-FX fiber ports with SC connectors for single-mode fiber, enabling reliable links over longer distances while preserving a copper segment where needed. Designed for the MM3 modular ecosystem used by Hirschmann MICE Switches, this module enables mixed copper/fiber topologies suitable for bridging local control networks to fiber backbones or remote sites. With 100 Mbps per port on both media types, the MM3-2FXS2/2TX1 supports Fast Ethernet connectivity across copper and fiber paths, making it a straightforward option for extending networks to field devices such as PLCs and HMIs without replacing existing Ethernet equipment. The MM3-2FXS2/2TX1-EEC designation confirms the same media capabilities in an official Belden Hirschmann part variant, reinforcing its role as a dedicated, field-grade module within the MM3 family.
