FEATURES
Description
LMP-1202G-SFP series – High-performance 12-port PoE+ managed Ethernet switches for industrial applications
The LMP-1202G-SFP series offers reliable and flexible network solutions for demanding industrial environments. With a total of 12 ports, including 8x Gigabit Ethernet ports with PoE+ support (IEEE 802.3at/af, up to 30 W/port), as well as 2x Gigabit combo ports (10/100/1000Tx or 100/1000Fx SFP ports), it enables efficient integration of end devices and fiber optic connections.
Efficient management and high reliability
The switches have advanced Layer 2 management functions that can be controlled via an intuitive web management interface. The integrated ERPS protocol (ITU-T G.8032) ensures ring network redundancy with a network recovery time of less than 50 ms to effectively minimize outages.
Advanced security and filtering functions
Thanks to advanced features such as IGMP, VLAN, QoS, SNMP, Port Lock, Modbus TCP and 802.1X/HTTPS/SSH/SSL, the LMP-1202G-SFP series offers the highest level of security and simplified network management for SCADA systems and control networks.
Robust design for extreme conditions
The series complies with protection class IP30 and supports DIN rail mounting. It is designed for use in demanding environments and offers models with an extended operating temperature range of -40 °C to 75 °C. In addition, it ensures high protection against EFT and ESD interference, making it ideal for applications in energy supply, water and wastewater management, factory automation, security monitoring and more.
