Specifications taken from the manufacturer datasheet.
Which version do I need?
Two part numbers, differing only by M12 coding: EMG8305-M12-A (1P1EMG8305A001G, A coding) and EMG8305-M12-X (1P1EMG8305X001G, X coding). Both provide 5 M12 ports. Order the coding that matches your installed M12 patch leads, as the two are not interchangeable.
Typical applications for the EMG8305
- Rolling stock and carriage-side railway networks
- Trackside and wayside equipment cabinets
- Installations with no protective enclosure available
- Washdown, dusty or high-vibration industrial areas
- Profinet networks requiring 802.1q packet prioritisation
- Surface-mounted installs where space is limited

EMG8305 — frequently asked questions
Is the EMG8305 managed or unmanaged?
Unmanaged. The datasheet describes it as a rugged 5-port IP67-rated unmanaged Ethernet switch using store-and-forward processing with an 8096-entry MAC address table. It does prioritise Profinet packets according to 802.1q, but there is no web interface or configuration.
Do I need an enclosure for it?
No. The housing is IP67 rated according to EN 60529 in an aluminium case, and the datasheet states it resists dust, dirt, liquid and vibration, making it suitable for the toughest industrial applications even without the need of additional housing.
What is the difference between the A-coding and X-coding versions?
Only the M12 connector coding on the five Ethernet ports: EMG8305-M12-A uses A coding and EMG8305-M12-X uses X coding. Choose the version matching your existing M12 cabling. The power connector is a 5-pin A-code male M12 on both.
What power does it need and how much does it draw?
A redundant 12-48 VDC input via 5-pin A-code male M12, drawing 0.42 A at 12 V for a maximum 5 W. Reverse polarity protection is fitted.
Is it approved for railway use?
The datasheet states it is compliant with the essential sections of EN 50155, covering operating temperature, power input voltage, EMC and vibration, and is certified to EN 50121-4 and UL 61010-2-201.
