Description

The SG803 series is a non-managed full Gigabit switch module independently developed by Lixun Electronics. It features 8 auto-negotiation Gigabit Ethernet ports. Two product variants are available: one with a PH2.0mm 8-pin socket and one with onboard 8-pin pins. It boasts high integration, compact size, rich features, and ease of use. Utilizing an embedded installation method, users can customize the PCB baseboard specifications. The module pins allow flexible selection of Ethernet interface types to meet the requirements of different application scenarios.

The hardware adopts a fanless, low-power, wide-temperature/wide-voltage design. Having passed stringent industry-standard tests, it can adapt to harsh industrial field environments with demanding EMC requirements. It is widely applicable in industrial fields such as smart grids, rail transit, smart cities, safe cities, new energy, and smart manufacturing.

Key Features

8 x 10/100/1000M Base-T PH2.0mm 8-pin socket ports (Data/Power).
8K MAC address table with auto-learning.16 Gbps non-blocking wire-speed switching fabric.
External power supply DC 5-60V (PH2.0 2-pin socket).
Module PCB dimensions: 68*70*10mm (L*W*H).

Product Characteristics

High-Speed Transmission, Stable Connectivity

Provides 8 x 10/100/1000M Base-T auto-negotiation PH2.0mm 8-pin socket ports, facilitating flexible networking for users to meet various scenario requirements. All ports support non-blocking wire-speed forwarding for smoother data transfer. Supports IEEE 802.3x full-duplex flow control and Backpressure half-duplex flow control.

Modular Design, Compact and Refined

High integration and compact size, with dimensions of only 68*70*10mm. Uses an embedded installation method, allowing users to customize PCB baseboard specifications. The module pins enable flexible selection of Ethernet interface types to meet the needs of different application sites.

Plug-and-Play, No Configuration Required

All 8 ports support MDI/MDIX auto-crossover and offer full wire-speed Gigabit switching capability. Plug-and-play, no management required, ensuring all ports forward without blocking. Users can easily monitor device status via the Power (PWR) LED and port status LEDs (Link, L/A).

Industrial Design, Wide Range of Applications

Hardware adopts a fanless, low-power, wide-temperature/wide-voltage design. Having passed stringent industry-standard tests, it can adapt to harsh industrial field environments with demanding EMC requirements. It is widely applicable in industrial fields such as smart grids, rail transit, smart cities, safe cities, new energy, and smart manufacturing.
