The M12 connectors ensure tight, robust connections, and guarantee reliable operation, even for applications that are subject to high vibration and shock. The TN-5308-4/8PoE series Ethernet switches provide 8 Fast Ethernet M12 ports with 4/8 IEEE 802.3af compliant PoE (Power-over-Ethernet) ports. The switches are classified as power source equipment (PSE) and provide up to 15.4 watts of power per port. The TN-5308-4/8PoE switches can be used to power IEEE 802.3af compliant powered devices (PDs), eliminating the need for additional wiring. The switches support IEEE 802.3/802.3u/802/3x with 10/100M, full/half-duplex, MDI/MDI-X auto-sensing, and provide an economical solution for your industrial Ethernet network. Models with an extended operating temperature range of -40 to 75°C are also available. The TN-5308-4/8 PoE series Ethernet switches comply with a portion of EN 50155 specifications, covering operating temperature, power input voltage, surge, ESD, and vibration, making the switches suitable for a variety of industrial applications. › ›4 or 8 IEEE 802.3af compliant PoE and Ethernet combo ports › ›Provides up to 15.4 watts at 48 VDC per PoE port › ›Complies with a portion of EN 50155 specifications › ›-40 to 75°C operating temperature range (T models) Power over Ethernet Technology Standards: IEEE 802.3 for 10BaseT IEEE 802.3u for 100BaseT(X) IEEE 802.3x for Flow Control IEEE 802.3af for Power-over-Ethernet Processing Type: Store and Forward Interface M12 Ports: 10/100BaseT(X) auto negotiation speed, F/H duplex mode and auto MDI/MDI-X connection Power Requirements Input Voltage: 48 VDC Operating Voltage: 46 to 50 V Input Current: • TN-5308-4PoE: 1.6 A @ 48 VDC • TN-5308-8PoE: 2.9 A @ 48 VDC Overload Current Protection: 3 A @ 48 VDC Connection: M12 connector Reverse Polarity Protection: 3 A @ 48 VDC PoE (per port) Max.
