Mini Industrial 3-Port 1000M RJ45 + 1 x SFP PD Switch with PoE Splitter Function

Mini Industrial 3-Port 10/100/1000T + 1-Port 100/1000X SFP PD Switch with PoE Splitter Function

Product Overview:

The LNK-IMC103G-SFP-PD is a compact industrial-grade PD switch with integrated PoE splitter functionality, designed for flexible network deployments in space-constrained and power-limited environments. This versatile device features 3× 10/100/1000BASE-T RJ45 ports and 1× 100/1000BASE-X SFP fiber optic slot, providing both copper and fiber connectivity options.

The dedicated "PoE IN" RJ45 port accepts IEEE 802.3af/at compliant power input from remote PSE switches or PoE injectors, eliminating the need for local power supplies while delivering 5-24V DC output (max 3A, 60W) to connected devices. The auto-adapting SFP port supports both 100Base-FX and 1000Base-X optical modules, enabling long-distance fiber extension of copper networks.

With DIN-rail mounting capability and optional L-bracket for wall or flat surface installation, this switch is ideal for industrial automation, outdoor surveillance, intelligent transportation systems, and other applications requiring reliable connectivity in harsh environments where both power availability and space are limited.

Product Feature

✅ Auto-Detecting SFP Fiber Connectivity: Features 100/1000BASE-X SFP slots with automatic fiber module detection, supporting both single-mode and multi-mode transceivers for flexible optical network expansion.

✅ Triple Gigabit Copper Ports: Includes 3× 10/100/1000M RJ-45 Ethernet ports with auto-negotiation and auto-MDI/MDIX for seamless device connectivity.

✅ Integrated PoE PD Input: Dedicated IEEE 802.3af/at compliant PoE PD port receives both power and data from PSE switches or injectors, eliminating local power supply requirements.

✅ Advanced DC Power Output: Delivers 5~24V DC output (max 3A, 60W) to support external devices such as wireless APs, IP cameras, and IoT sensors.

✅ Energy Efficiency Compliance: Meets IEEE 802.3az EEE standards, reducing power consumption during low network activity for environmentally conscious operations.

✅ Flexible Mounting Options: Supports both DIN-rail and wall-mount installation with included L-bracket, enabling versatile deployment in control cabinets and space-limited environments.

✅ Compact Industrial Design: Space-optimized form factor with wide-temperature operation suitable for harsh industrial and outdoor applications.

✅ Plug-and-Play Operation: Requires no configuration for immediate deployment in network expansion and power distribution scenarios.

Application Scenarios

• PoE-Powered Network Extensions: Deploys as PD (Powered Device) receiving IEEE 802.3af/at compliant power from PSE switches or injectors, eliminating local power needs in remote or hard-to-wire locations.

• Fiber-Optic Backbone Access: Utilizes 100/1000BASE-X SFP slot with auto-detection for integrating copper-based devices into fiber optic networks across extended distances.

• Industrial IoT Deployments: Supports sensors, controllers, and edge devices with 5-24V DC output (max 60W), ideal for automation systems and smart infrastructure.

• Outdoor and Harsh Environment Connectivity: Compact, DIN-rail/wall-mount design enables reliable operation in temperature-variable and vibration-prone settings like transportation or utility networks.

• Wireless Network Expansion: Powers and connects wireless access points, 5G small cells, or network extenders using PoE passthrough and fiber uplink capabilities.

• Space-Constrained Installations: Suitable for control cabinets, roadside boxes, and ceiling voids where compact size and integrated power conversion are critical.

• Cost-Effective Network Upgrades: Allows migration to fiber and centralized power management without additional electrical work, supporting legacy and modern devices.
