The TN-5308A PoE Series extends the ToughNet range with 8-port unmanaged PoE switches designed for power delivery in harsh environments. Featuring eight M12 D-coded 10/100BaseT(X) PoE ports, these models support IEEE 802.3af/at standards, supplying up to 30 W per port with a total PoE budget of 50.2 W. Classified as Power Sourcing Equipment (PSE), the switches power devices such as IP cameras, wireless APs, and VoIP phones directly over Ethernet cabling.
Built to comply with EN 50155 railway standards, these models endure the toughest requirements for power supply variations, ESD, surge immunity, vibration, and temperature extremes. With a rugged IP54-rated housing and M12 connectors, they guarantee secure, shock-resistant connectivity for rolling stock and outdoor deployments.
Supporting auto-negotiation, full/half-duplex, MDI/MDI-X, and IEEE 802.3x flow control, the switches are simple to integrate into existing networks. A 768 kbit packet buffer and 2K MAC table ensure smooth packet forwarding even under high data loads.
With a 24–110 VDC input range (16.8–137.5 VDC operating) and protections against reverse polarity, overload, and inrush current, the TN-5308A PoE delivers safe, continuous operation. Dimensions of 72.4 x 190.4 x 50 mm and wall/DIN-mount options provide flexibility in installation.
With EN 50121-4 railway compliance, NEMA TS-2 certification, and an MTBF over 1.8 million hours, these switches are purpose-built for reliable industrial Ethernet with integrated PoE.
