Product Detail
Description
The SH-G0408 series industrial-grade unmanaged ethernet switch is outfitted with 8×10/100/1000M auto-sensed RJ45 ports and 4x1000M fiber ports. Its auto-sensing function seamlessly adjusts to 10/100/1000Mbps speeds, supporting flexible connectivity for a large number of end devices—from industrial sensors to high-definition IP cameras—while the 4 fiber ports enable long-distance, anti-interference data transmission for backbone network links. Engineered specifically for harsh environments, this industrial ethernet switch boasts a broad operating temperature range of -40°C to +85°C, a fanless design that prevents dust accumulation and reduces noise, a space-efficient compact structure, and DIN rail mounting for easy installation in crowded industrial cabinets.
This reliable unmanaged ethernet switch delivers consistent performance across diverse tough scenarios, whether in freezing outdoor control systems for transportation, high-heat workshops in oil fields, or dusty port equipment rooms. Its durable build and low-maintenance features make it a preferred choice for industries including transportation, telecommunications, security, banking, customs, ports, power stations, and oil fields. By balancing high-density terminal access (via 8 RJ45 ports) and stable backbone transmission (via 4 fiber ports), it ensures uninterrupted data flow even in extreme working conditions.
