Description
Product Overview
The EtherWAN EX42011-1B-1-A is an industrial Fast Ethernet media converter that connects one 10/100BASE-TX copper Ethernet port to a 100BASE-FX multimode fiber interface. Its 1310 nm ST optical configuration is rated for up to 2 km, while a 12–48VDC terminal-block input, 4 kV data-port surge protection and compact IP30 housing support suitable industrial equipment installations. The unit can be mounted on a 35 mm DIN rail or a panel and operates from -10°C to +60°C. Confirm fiber compatibility, far-end optics and DC power before ordering.
The EtherWAN EX42011-1B-1-A is an industrial 10/100BASE-TX to 100BASE-FX Ethernet media converter offered by Coremicro in Union City, California. EtherWAN identifies the 1B optical option as multimode ST at 1310 nm for a rated distance of 2 km. The converter specifies one RJ45 copper port, one 100BASE-FX fiber port, 12–48VDC terminal-block input, maximum 1.82W power consumption, 4 kV surge protection on the data port, -10°C to +60°C operating temperature, a plastic IP30 housing and 35 mm DIN-rail or panel mounting. Coremicro displays Special Order and Authorized Dealer designations for this listing. Verify current availability, manufacturer warranty, power-supply contents and far-end optical compatibility before purchase.
10/100BASE-TX to 100BASE-FX Conversion
Connect a compatible 10/100 Mbps RJ45 Ethernet device to a 100 Mbps fiber link. The converter provides one copper port and one 100BASE-FX optical port; it is not a Gigabit media converter.
2 km Multimode Fiber Reach
The 1B optical configuration supports a manufacturer-rated distance of up to 2 km over compatible multimode fiber. Check the installed fiber path, attenuation and far-end optical interface before deployment.
1310 nm ST Fiber Interface
The fixed non-WDM 100BASE-FX optical interface uses a 1310 nm wavelength and ST connector. This multimode ST version differs from the SC, single-mode and WDM alternatives within the EX42011 Series.
12–48VDC Input and Low Power Draw
Power is supplied through a terminal block with a 12–48VDC input range. EtherWAN specifies 1.82W maximum consumption and reverse-polarity protection; confirm the external supply meets installation requirements.
4 kV Surge Protection on Data Ports
Augmented signal-port surge protection is specified at ±4 kV line-to-ground under EN 61000-4-5. Proper grounding and the rest of the installation design remain essential.
Compact IP30 DIN-Rail Installation
The 26 × 70 × 110 mm plastic IP30 enclosure supports 35 mm top-hat DIN-rail or panel mounting. The DIN-rail mounting kit is included; use a protected cabinet appropriate for the -10°C to +60°C operating range.
