Fast Ethernet Media Converters — HMC-IMI-F1N
HMC-IMI-F1N Mini-Type Industrial Fast Ethernet Media Converter
Mini-Type. Copper to Fibre. DIN-Rail Ready. Built for Where Space is Tight. SC and ST connector support.
Product overview
The Smallest Box That Does the Full Job
The HMC-IMI-F1N is a mini-type industrial Fast Ethernet media converter that converts 10/100Base-TX copper signals to 100Base-FX fibre in a compact aluminium housing that's 22% smaller than the standard HMC-HMT-F1S. At 95mm in length and 120g, it's the most space-efficient industrial media converter in the HEPDA range — and it doesn't trade capability for size.
It supports both multimode (2km) and single-mode (20km) fibre, runs on 12V DC terminal block input, and mounts to a DIN-rail or wall without modification. No software. No complex setup. Configuration is handled entirely through onboard DIP switches.
SC and ST connector support
Compatible with legacy ST and newer SC installations
Store-and-forward processing
Corrupted frames from noisy environments are dropped at the converter
Features
HMC-IMI-F1N Mini-Type Industrial Fast Ethernet Media Converter
Ultra-compact: 38.5 × 95 × 24.5mm
22% smaller than the HMC-HMT-F1S. Fits inside camera housings, trackside cabinets, and wall-mounted field enclosures.
DIP Switch Configuration — No Software
LFP, ALS, FX Reset, and FX Speed — configurable on the unit. Set in the field and walk away.
SC and ST Connector Support
Compatible with legacy ST and newer SC installations — fewer SKUs to manage.
Store-and-Forward Processing
Corrupted frames from electrically noisy environments are dropped at the converter.
Terminal Block Power Input
12V DC terminal block connects directly to standard industrial DIN-rail power supplies.
MTBF over 100,000 hours
High MTBF means fewer field replacements and lower lifecycle maintenance costs.

Applications
Where it is deployed
Roadside and Pole-Mount Surveillance
Natural fit for smaller pole-mount or wall-mount enclosures used in roadside, utility, and transport infrastructure.
MRT Trackside and Rail Infrastructure
Trackside cabinets have limited internal space. Fits where full-size converters won't.
Control Room and Panel Integration
High-density installations where multiple converters must fit in a single enclosure.
Factory Floor Edge Nodes
PLCs and SCADA systems on factory floors need fibre connections to avoid EMI from motors and drives.
Water and Utility Infrastructure
Pump stations and remote monitoring stations where enclosure space is limited.
Temporary and Construction Site Networks
Compact DIN-rail form factor installs and relocates quickly.
