Antaira GNX-1600G 16-Port Gigabit Unmanaged Industrial Ethernet Switches with Extended Temperature Options

When 16 devices in one cabinet all need Gigabit links, a single DIN-rail switch with a 32 Gbps switching fabric avoids chaining smaller switches and the extra failure points that come with them. The Antaira GNX-1600G series covers that with unmanaged industrial Ethernet switches that pass traffic as soon as they are powered: 16 Gigabit RJ45 ports in a slim IP50 aluminium housing for a DIN rail or a wall, with nothing to configure on site.

Every GNX-1600G has 16 10/100/1000Base-T(X) RJ45 ports with auto negotiation, auto MDI/MDI-X and full or half duplex, for PLCs, HMIs, cameras and uplinks on Cat.5e or better cable up to 100 m. Switching is unmanaged and store-and-forward, on a 32 Gbps switching fabric and an 8K MAC address table, with IEEE 802.3x flow control and 9 KB jumbo frames. There is nothing to set up. Power arrives on dual redundant 12 to 56 V DC inputs through a removable 6-pin terminal block, so a second supply can take over if the first fails. An alarm relay contact rated 1 A at 24 V DC flags a lost feed to a PLC or alarm panel. Reverse polarity and overload current protection are built in, and each switch draws 10.64 W at full load. ESD protection reaches 6 kV contact and 8 kV air, with EFT and surge to 2 kV.

The series has two builds that differ only in temperature rating. The GNX-1600G is the standard build, rated -10 °C to 70 °C for indoor panels and heated cabinets. The GNX-1600G-T is the extended temperature build, rated -40 °C to 75 °C for unheated outdoor enclosures, roadside cabinets and camera poles. Both share the same ports, switching, power input and approvals, so a scheme can mix them by location. Where the devices also need power over the cable, the GNP-1600G series series adds PoE+ from a 300 W budget.

Antaira names industrial automation, IP surveillance, traffic monitoring, security, transportation and telecom among the applications for the GNX-1600G series. Both models are tested for shock, vibration and free fall to EN 60068-2-27, EN 60068-2-6 and EN 60068-2-31, store from -40 °C to 85 °C and tolerate 5 to 95% non-condensing humidity. They comply with UL 62368-1 (MET), carry LVD, CE and FCC Class A marks, are listed by Antaira as TAA and NDAA compliant and come with Antaira’s 5-year warranty. We supply the GNX-1600G across the UK and can help choose the temperature grade, size the DC supply and specify the cabling for each cabinet.
