Unmanaged Switch Digitus DN-651132 8 Port Fast Ethernet 1 SFP Uplink

The Digitus DN-651132 is an industrial-grade unmanaged Ethernet switch with 8 Fast Ethernet (10/100 Mbps) RJ45 ports and 1 100 Mbps fiber uplink (SFP). Designed for harsh environments, it supports non-blocking wire-speed performance, DC 12–48V power input with reverse-polarity protection, and offers durable operation with an average MTBF above 300,000 hours. The compact, rail-mountable metal housing with IP40 protection and LED indicators allows installation in control cabinets and other confined spaces.

Advantages

The switch uses high-quality photoelectric integration modules to ensure stable optical and electrical characteristics and reliable data transmission. It supports full duplex and half duplex modes with auto-negotiation, automatic MDI/MDIX detection on network ports, and an internal store-and-forward mechanism. Surge protection on the power input (5000 A, 8/20 µs) and a wide operating temperature range (−40 °C to 80 °C) increase resilience in industrial installations.

Suitable for

• Industrial Ethernet networks in factories and plants
• Connecting IP cameras and other PoE-capable devices in surveillance systems (when PoE is provided elsewhere)
• Network extension where a compact, rail-mountable unmanaged switch is required
• Rugged environments with wide temperature requirements

How to use

Mount the switch on a standard DIN rail inside a suitably ventilated enclosure or cabinet. Connect the DC power to the 6‑pin terminal block, observing polarity; the device includes reverse-polarity protection. Use standard Ethernet cables to attach devices to the 8 RJ45 ports and install an SFP module in the fiber slot for uplink. The switch is unmanaged and operates plug-and-play with auto-negotiation and automatic MDI/MDIX, so no configuration is required.

Recommendations

Install the switch in locations that meet the specified temperature range and protect it from direct water exposure. Ensure proper grounding and use surge protection on external cables where needed. Verify power supply voltage is within 12–48 V DC to avoid damage.
