Request a price
The ATOP EH3305 is a slim unmanaged industrial switch with 5 × 10/100BASE-T(X) RJ45 ports in a 23 mm wide, IP30 metal DIN-rail housing. It runs from 12-48 VDC on redundant power inputs and is rated from -40 to +75°C, so it suits outdoor cabinets, unheated enclosures and machine panels that need a plug-and-play Fast Ethernet switch in very little space.

Description
EH3305 is a slim, entry-level unmanaged switch with 5 RJ-45 ports and strict QoS packet prioritization according to 802.1p. Designed for industrial and especially for hazardous locations, it fits into small spaces in cabinets or between walls, and complies with CE, FCC and UL standards, while featuring a robust metal housing.
Redundant power inputs allow simultaneous connection to wide-range DC power sources, so in case one of the power inputs fail, the other live source automatically acts as a backup to provide power.

Specifications taken from the manufacturer datasheet.
Which version do I need?
ATOP's documents list one orderable code, EH3305, with no port or PoE variants. It is the wide-temperature, metal-housed Fast Ethernet member of ATOP's slim 5-port family: EH3005 is the same port count in plastic (0 to +60°C), and EHG3305 is the Gigabit equivalent in the same metal housing. Choose EH3305 when the devices are 10/100 and the cabinet is unheated, outdoors or subject to wide temperature swings.
Typical applications for the EH3305
- Outdoor and unheated field cabinets that need a few Ethernet ports
- Machine panels and control cabinets with very little DIN-rail space
- Connecting PLCs, HMIs and remote I/O in Profinet cells without switch configuration
- Roadside, utility and water-site enclosures operating down to -40°C
- Narrow enclosures and between-wall installations where a 23 mm wide unit fits
- Dual-fed DC panels using redundant 12-48 VDC supplies

EH3305 — frequently asked questions
How many ports does the EH3305 have?
Five 10/100BASE-T(X) RJ45 ports, with no fibre or PoE ports. The EHG3305 offers the same slim metal format with 5 × 10/100/1000BASE-T(X) ports.
What is the difference between the EH3305 and the EH3005?
The EH3305 has a metal housing rated -40 to +75°C (storage -40 to +85°C). The EH3005 has the same 5 × 10/100 ports in a plastic housing rated 0 to +60°C.
What power input does it take?
12-48 VDC on redundant power inputs. Both can be connected simultaneously, and if one fails the other source takes over automatically.
Can it be used in a cold outdoor cabinet?
Yes, it is rated for operation from -40 to +75°C and storage from -40 to +85°C, and ATOP recommends it within the slim range for harsher environments.
Does an unmanaged switch handle VLAN-tagged or Profinet traffic?
It supports IEEE 802.1q VLAN tagging and IEEE 802.1p Class of Service, prioritising tagged packets without configuration. ATOP lists the EH3305 as Profinet CC-A.
Which approvals does it carry?
UL/EN/IEC (CB) 60950-1 and/or 62368-1, and it complies with CE, FCC and UL standards. ATOP's guide does not tick ATEX, UL Class I Div 2, E-Mark or EN 50155 for this model.
