Fast Ethernet Media Converters — HMC-HMT-F1S
HMC-HMT-F1S Industrial Fast Ethernet Media Converter
Copper to Fibre. Long Distance. EMI-Proof. Ready to Deploy. –40°C to +75°C. 12V DC. DIN-rail or wall mount.
Product overview
Copper-to-Fibre Conversion Built for the Factory Floor, Not the IT Closet
The HMC-HMT-F1S converts 10/100 Mbps RJ45 copper signals to 100Base fibre over an SC connector. It supports both multimode fibre (up to 2km) and single-mode fibre (up to 20km) depending on the SFP module installed.
This converter was designed for environments where heat, vibration, and electrical noise are part of daily operation. The –40°C to +75°C operating range means it handles everything from cold outdoor enclosures to the heat generated inside a busy factory control cabinet. EMI, ESD, EFT, and surge protection are built in. Power input is 12V DC, and the unit draws just 2.4W.
Multimode — up to 2km
50/62.5μm · within a single building or site
Single-Mode — up to 20km
9μm · across buildings, campuses, remote field locations
Features
HMC-HMT-F1S Industrial Fast Ethernet Media Converter
–40°C to +75°C Operating Range
Industrial temperature range — handles tropical outdoor enclosures to the heat inside a busy factory control cabinet.
Full EMC Compliance Built In
Meets EN55022, EN55024, and IEC 61000-4 series standards for EMI/EMS.
DIP Switch Configuration
LFP, ALS, and FX Reset — configurable on the unit without software.
Multimode and Single-Mode Options
Both fibre configurations share the same base hardware.
DIN-Rail Mounting as Standard
Installs directly onto standard DIN rails inside control panels.
MTBF over 100,000 hours
Lower maintenance frequency means lower total cost of ownership.
