Industrial Ethernet Switch 3-Port 10/100/1000M Gigabit + 1000M SC Fiber DIN Rail

Mini Industrial 3-Port 10/100/1000T + 1-Port 1000X SC Gigabit Ethernet Switch

Product Overview:

The LNK-IMC103G Series is a compact industrial-grade Gigabit Ethernet switch designed for robust network performance in demanding environments. Featuring three auto-negotiation 10/100/1000BASE-T copper ports and one 1000BASE-X SC fiber port, it enables seamless integration of copper and fiber networks while supporting both single-mode and multi-mode fiber connections (1 or 2 core).

Housed in an IP40-rated rugged metal enclosure, this hardened switch operates reliably across an extended temperature range of -40°C to +75°C, ensuring stable performance in harsh conditions including industrial automation, outdoor surveillance, and transportation systems. It supports both half and full-duplex transmission modes with auto-negotiation for optimal network flexibility.

Ideal for network integration between remote locations, this switch provides reliable connectivity for IP cameras, wireless access points, and other network devices. Its compact design allows for easy installation in space-constrained applications while maintaining industrial-grade durability and performance standards.

Features Description:

• Triple Gigabit Copper Ports with Auto-Sensing: Three 10/100/1000BASE-T RJ45 interfaces feature auto MDI/MDI-X detection, enabling plug-and-play deployment without manual cable configuration

• Dedicated Fiber Uplink Port: Integrated 1000BASE-X SC fiber optic interface provides reliable long-distance connectivity with single-mode or multi-mode fiber support

• Adaptive Duplex Operation & Negotiation: Automatically configures full/half-duplex modes and negotiates optimal transmission speeds for efficient network performance

• Energy Efficient Ethernet Compliance: Reduces power consumption by up to 80% during low-data periods while maintaining IEEE 802.3az EEE standards compliance

• Wide-Range Terminal Block Power Input: Accepts 12-48VDC through industrial-grade screw terminals, ensuring stable operation in environments with voltage fluctuations

• Rugged IP40 Aluminum Housing: Features industrial-grade metal casing providing electromagnetic shielding and physical protection in harsh environments

• Flexible Mounting Options: Supports both DIN-rail and wall-mount installation for easy deployment in control cabinets and space-constrained locations

• Extended Temperature Operation: Hardened for reliable performance in extreme environments from -40°C to 75°C (-40°F to 167°F), suitable for outdoor and unheated installations

Application Scenarios

• Industrial Automation Networks: Provides reliable connectivity for PLCs, HMIs, and motor control systems in manufacturing facilities with real-time data transmission requirements

• IP Surveillance and Security Systems: Supports high-resolution IP cameras, NVRs, and access control devices across extended distances with fiber backbone connectivity

• Intelligent Transportation Systems (ITS): Enables traffic monitoring, vehicle detection, and roadside communication networks in wide-temperature environments (-40°C to 75°C)

• Outdoor Wireless Deployments: Facilitates WLAN access points, 4G/5G small cells, and microwave links with reliable fiber uplink capabilities

• Power Utility and Energy Infrastructure: Suitable for substation automation, grid monitoring, and renewable energy systems requiring electrical isolation

• Building Automation Systems: Supports network integration for environmental controls, smart lighting, and building management applications

• Marine and Offshore Applications: Provides corrosion-resistant network connectivity for vessel communication systems and offshore platform monitoring

• Mining and Heavy Industry: Operates reliably in vibration-intensive environments for mining equipment connectivity and remote monitoring systems
