Network Switch Digitus 4 Port Fast Ethernet Industrial Unmanaged

The DIGITUS Network Switch 4 Port Fast Ethernet Industrial Unmanaged (DN-650105) is an unmanaged L2 switch designed for industrial environments. It provides four 10/100Base-TX Fast Ethernet ports plus one RJ45 uplink, supports full-duplex operation and a MAC address table with 2048 entries. The switch meets IEEE 802.3/802.3u/802.3x standards, offers a switching capacity of 1 Gbit/s and operates from a DC input of 12–48 V. Built for harsh conditions, it can be mounted on DIN rail or wall and withstands challenging temperature ranges and vibrations common in transport, production and monitoring applications.

Advantages

The unmanaged DIGITUS industrial switch delivers reliable wired connectivity with a compact, robust design suitable for demanding environments. Its Fast Ethernet ports and RJ45 uplink provide straightforward network expansion without configuration. The device supports full-duplex switching and a 2048-entry MAC table to ensure efficient frame forwarding. DIN rail and wall-mount options simplify installation in control cabinets and industrial sites.

How to use

Install the switch on a DIN rail or secure it to a wall surface in a dry, ventilated location within the permitted temperature range. Connect the DC power source (12–48 V) to the appropriate terminals following the manufacturer wiring instructions. Use standard Cat5e/Cat6 cables to connect devices to the four Fast Ethernet ports and the RJ45 uplink for upstream connection. The unmanaged device requires no configuration; devices will negotiate link speed and duplex automatically.

Recommendations

Place the switch in an environment protected from direct water ingress and excessive mechanical shock. Use shielded cables and proper grounding in electrically noisy industrial installations. Verify power supply polarity and voltage range before connecting; ensure adequate ventilation around the unit to avoid overheating.
