Industrial 5-Port Switch

This unmanaged switch provides five RJ45 Fast Ethernet ports operating at 10/100 Mbps for connecting PLCs, sensors and IP devices in industrial automation and smart transportation networks. It mounts directly on standard DIN-rail inside control cabinets and weak-current boxes. The metal housing carries an IP30 rating for rugged environments.

Sustained Load Behaviour

Store-and-forward switching with frame filtering and IEEE 802.3x flow control on full duplex links reduces packet loss during continuous traffic from automation equipment. A 9216-byte jumbo frame limit and 1522-byte maximum packet length handle larger industrial frames. The 100 megabits_per_second forwarding rate defines the throughput ceiling under constant load.

Interface Practical Limits

Five 10/100 Mbps RJ45 ports with auto MDI/MDI-X set the hard bandwidth ceiling at 100 Mbps per link, with no gigabit uplink available on this model. Triple redundant 952V DC inputs allow up to three power sources for uptime during source interruption. Operating range spans -40°C to 70°C for unheated outdoor cabinets.

Questions about this item

How does the fanless metal housing dissipate heat when running continuously in a 70°C cabinet?

The IP30 metal enclosure is rated for -40°C to 70°C operation without active cooling, relying on passive conduction through the rugged housing to maintain stability in control cabinets and factory floors.

What DC power sources must already be available to use the triple redundant inputs?

You need up to three independent 952V DC supplies with correct polarity; the anti-reverse connection feature protects the switch if a source is wired backwards.

Will the 10/100Mbps ports negotiate correctly with legacy 10Mbps PLCs and sensors kept on the same network?

Yes, each RJ45 port supports auto MDI/MDI-X and automatic address learning/aging, so older 10Mbps devices connect without manual configuration while IEEE 802.3x flow control and backpressure reduce packet loss.
