Overview
About the HMC-IMF2MSC
The Hepda HMC-IMF Series is a compact, industrial-grade media converter that bridges 10/100Base-TX copper Ethernet to 100Base-FX fiber optic networks. Designed for seamless protocol conversion, it supports both single-mode and multimode fiber with single or dual-core (BiDi) configurations, enabling flexible deployment in industrial environments.
Housed in a compact IP40-rated aluminum enclosure with wall-mount installation, the HMC-IMF2MSC accepts universal DC 12V / 24V or AC 24V terminal block power inputs and operates from −20 to +70°C. Its plug-and-play design with Auto-Negotiation and MDI/MDI-X auto-crossover eliminates manual configuration, while a DIP-switch-selectable Link Fault Pass Through (LFP) feature ensures end-to-end link monitoring.
