Industrial Ethernet Switch 1000M 4-Port Gigabit RJ45 to 2-port Fiber DIN Rail

Industrial 4-port 10/100/1000Base-T + 2-port 1000BASE-X

Ethernet Switch

Product Overview:

The LNK-IMC204G is an industrial-grade Gigabit Ethernet switch designed for robust network performance in demanding environments. Featuring four 10/100/1000BASE-TX copper ports and two 1000BASE-X fiber optic ports, it enables seamless media conversion and network redundancy. The RJ45 ports support auto-negotiation for 10/100/1000Mbps speeds, full/half duplex operation, and automatic MDI/MDI-X crossover detection. The dual fiber ports accommodate both single-mode and multi-mode transceivers with single or dual fiber core connectivity options for reliable long-distance communication.

Engineered for industrial applications, this hardened switch operates reliably in extreme conditions with a rugged metal housing that provides superior protection against vibration, shock, and electromagnetic interference. Its dual fiber port design offers link redundancy and increased bandwidth capacity, making it ideal for critical network infrastructure where uninterrupted connectivity is essential.

Ideal for network integration between remote locations, this switch provides reliable connectivity for IP cameras, wireless access points, and other network devices in applications including industrial automation, transportation systems, and surveillance networks. The combination of copper ports and dual fiber connectivity makes it perfect for creating redundant network paths while maintaining data integrity in electrically noisy environments.

Features Description:

• Hybrid Network Connectivity: 4×10/100/1000BASE-TX copper ports + 2×1000BASE-FX fiber ports for flexible media conversion and dual-fiber redundancy

• Auto-Negotiating RJ45 Ports: Supports 10/100/1000Mbps speeds with full/half-duplex auto-negotiation and automatic MDI/MDIX crossover detection

• Advanced Flow Control: Implements 802.3x flow control to prevent packet loss and ensure smooth data transmission in high-traffic networks

• Energy Efficient Design: Complies with IEEE 802.3az EEE standards, reducing power consumption by up to 80% during low network activity

• Dual Power Input Redundancy: Features redundant power inputs for continuous operation and enhanced system reliability in critical applications

• Flexible Installation Options: Supports both wall-mount and DIN-rail installation for versatile deployment in various industrial environments

• Extended Temperature Tolerance: Operates reliably in extreme temperatures from -40°C to 80°C (-40°F to 176°F) for harsh indoor/outdoor applications

• Industrial-Grade Protection: Built with robust EMI shielding and surge protection for operation in electrically noisy environments

• Dual Fiber Port Advantage: Provides link redundancy and load balancing capabilities for mission-critical network connections
