Antaira LMP-1600G-M12-67-110-T 16-Port Gigabit Managed M12 Ethernet Switch with 16x PoE+, 24-110V DC Railway Input and -40 to 70 °C

Enclosures that sit outdoors on railway and heavy industrial sites face vibration, liquid and dust as well as hard frost, often on a DC supply well above 48 V. The LMP-1600G-M12-67-110-T is the extended temperature, 24 to 110 V model in the Antaira LMP-1600G-M12-67-110 series, an IP67 16-port Light Layer 3 managed M12 switch with 16 PoE+ ports on X-coded M12 connectors.

All 16 of the 10/100/1000 ports use 8-pin X-coded M12 female connectors with IEEE 802.3at/af PoE+ at up to 30 W, drawing on a 120 W total budget. Store-and-forward switching runs on a 32 Gbps fabric with a 32K MAC table. The Light Layer 3 firmware adds static routes and DHCP Option 82 to VLANs, QoS, IGMP and LACP, and ITU-T G.8032 ERPS v2 restores the ring in under 50 ms, with STP, RSTP and MSTP also available.

Redundant 24 to 110 V DC inputs arrive on a K-coded M12 power connector, with overload current and reverse polarity protection, and the switch draws 45 W itself. Bypass protection on ports 8 and 16 keeps a daisy chain passing traffic if the switch loses power. PoE scheduling, output limits and a PoE ping alarm that power-cycles a hung device give control over each port, and a digital input, a relay contact, RADIUS, TACACS+, ACLs and IP Source Guard complete the toolset.

The LMP-1600G-M12-67-110-T runs from -40 °C to 70 °C in a sealed IP67 metal case for wall mounting, with console and USB backup ports on A-coded M12 connectors. Antaira lists FCC and CE marks with EN 50121-3-2 and EN 50121-4 railway EMC compliance, and covers it with its 5-year warranty. The LMP-1600G-M12-67-110 is the -10 °C to 65 °C model, and the LMP-1600G-M12-67-24-T takes 24 to 55 V DC with a 240 W budget. We supply and specify the switch, and can pre-configure IP addressing, VLANs and ring settings on request.
