Unmanaged Switch PLANET IFGS-620TF 4 Ports Fast Ethernet 10/100

PLANET IFGS-620TF is a compact unmanaged industrial Ring Ethernet switch with four 10/100BASE-TX copper ports and two 1000BASE-X SFP fiber ports in an IP30-rated rugged case. Designed to operate from -40 to 75 °C and to accept wide-range redundant power (9–48V DC or 24V AC), the IFGS-620TF provides stable long-range data transmission and can be mounted in space-limited or harsh environments. The switch supports full-duplex communication, a 4.8 Gbit/s switching capacity and a 4000-entry MAC address table, making it suitable for basic industrial networking and IIoT deployments.

Advantages

The IFGS-620TF offers fast ring recovery technology with a recovery time as low as 1 ms in small ring topologies, PROFINET traffic prioritization for faster delivery of industrial automation traffic, dual SFP fiber uplinks to extend network reach up to 120 km (with appropriate SFP modules), and a dual wide-range power input for high availability. Energy-efficient features (IEEE 802.3az) and ESD/surge protection (±6 kV contact/air and ±6 kV surge immunity) further increase reliability and lower operational costs.

Suitable for

• Small to medium industrial networks requiring redundant ring topology
• Factory automation and PROFINET device connectivity
• Long-distance uplink links using SFP fiber (FTTB/FTTC/FTTH scenarios)
• Space-limited installations such as wall enclosures or control cabinets

How to use

Install the IFGS-620TF on a DIN rail or fix it to a wall enclosure in your control room or cabinet. Insert appropriate 1000BASE-X SFP transceivers into the SFP slots for fiber uplinks when long-distance connections are required. Connect copper devices to the 10/100BASE-TX RJ-45 ports. Configure power by supplying redundant power sources (9–48V DC or 24V AC) to the dual inputs to enable automatic hardware failover. The switch is unmanaged and operates plug-and-play; for ring redundancy enable the One Key Ring function via the DIP switch according to the network topology documentation.

Recommendations

Use compatible SFP modules (multi-mode or single-mode) matched to fiber type and distance requirements, place the switch inside an IP30-protected enclosure if exposed to dust or debris, and provide redundant power sources to maximize uptime. When integrating with PROFINET devices, ensure QoS-sensitive traffic is routed through the IFGS-620TF to take advantage of PROFINET prioritization.
