Antaira LMX-0800 8-Port Fast Ethernet Managed Industrial Network Switches with Extended Temperature Options

Most control cabinets still run their PLCs, remote I/O and drives at 100 Mbps, and what they need from a switch is enough ports, a ring that heals quickly and a warning when something fails. The Antaira LMX-0800 series provides eight managed Fast Ethernet ports in an IP30 metal DIN rail case, built around those needs.

Both models share one design. Eight 10/100Base-TX RJ45 ports switch store-and-forward with an 8K MAC table and a 4 Mbit buffer. The Layer 2 managed firmware covers IEEE 802.1Q VLANs, QoS with CoS/ToS, IGMP v1/v2 snooping for up to 256 groups, LACP, LLDP, RMON, IPv4/IPv6, DHCP Option 66/67/82, Modbus TCP and 802.1X with HTTPS and SSH/SSL. ITU-T G.8032 ERPS recovers a ring in under 50 ms, with STP, RSTP and MSTP available, and exceptions can trigger an e-mail or the relay output. Redundant 12 to 48 V DC inputs land on a 6-contact terminal block, with overload and reverse polarity protection, a CPU watchdog and a 15 W draw.

Choose by temperature. The LMX-0800 is the standard build, rated -10 °C to 70 °C for heated or indoor cabinets. The LMX-0800-T is the extended temperature build, rated -40 °C to 75 °C for unheated outstations and roadside enclosures. For gigabit on the same design, the Antaira LMX-0800G series is the equivalent, and the LMX-0802 series swaps two copper ports for 100FX fibre.

Antaira names power and utility, water and wastewater, oil, gas and mining, factory automation, ITS and security surveillance within transportation as typical applications for the LMX-0800 series, with high EFT and ESD protection built in. Each case is tested for shock to IEC 60068-2-27, vibration to IEC 60068-2-6 and free fall to IEC 60068-2-32, with storage from -40 °C to 85 °C and 5% to 95% non-condensing humidity. Each switch is managed through the web console, Telnet or CLI, with an RS232 console port on RJ45 and USB 2.0 configuration backup. The series is UL 61010-1 certified, carries FCC and CE marks, is RoHS compliant and comes with Antaira’s 5-year warranty, and we can pre-configure IP addressing, VLANs and ring settings before it ships.
