The TN-5308A Series is a family of unmanaged Fast Ethernet switches built for harsh industrial and railway environments. With eight 10/100BaseT(X) M12 D-coded ports, these models ensure vibration-resistant, secure connections for rolling stock and industrial applications. The M12 connectors guarantee robust performance against shock and environmental disturbances, making them ideal for mobile and outdoor systems.
Compliant with the EN 50155 standard, the TN-5308A Series meets railway-grade requirements for EMC, vibration, surge protection, and power stability. Designed for extreme conditions, they operate in temperatures from -40 to 70 °C and withstand humidity, dust, and other environmental stresses.
The switches support IEEE 802.3/802.3u/802.3x, full/half-duplex modes, auto-negotiation, and MDI/MDI-X auto-sensing, ensuring simple plug-and-play integration. With a packet buffer of 768 kbits and 2K MAC address table, they provide reliable packet forwarding for industrial communications and monitoring systems.
Power is supplied via a single isolated 24–110 VDC input (16.8–137.5 VDC operating), with reverse polarity, overload, and inrush current protection to ensure reliable operation. Compact dimensions (62.4 x 190.4 x 37.5 mm) and flexible mounting options (DIN-rail or wall-mount) simplify installation in constrained spaces.
Certified to EN 50155, EN 50121-4, and NEMA TS-2, these switches meet rigorous requirements for railway and traffic control systems. With a 5-year warranty and MTBF exceeding 5.2 million hours, the TN-5308A non-PoE models deliver long-term reliability and cost-effective performance for industrial Ethernet applications.
