Introduction
The ToughNet TN-4500A Series M12 managed Ethernet switches
are designed for railway applications, including rolling stock and wayside
installations. The switches use M12 and other circular connectors to ensure
tight, robust connections, and guarantee reliable operation in industrial
environments where vibration and shock are commonplace. The TN-4500A Series
Ethernet switches provide 12 or 24 fast Ethernet M12 ports with or without IEEE
802.3at/af compliant PoE functionality, and the Gigabit models have 4 Gigabit
Ethernet interfaces with PoE and optional bypass relay functionality. In
addition, the fiber models provide 2 Gigabit fiber interface ports with an
embedded 2 km multimode fiber transceiver. The PoE switches are classified as
power source equipment (PSE).
The switches provide up to 30 watts of power per port, and
can be used to power IEEE 802.3at/af compliant powered devices (PDs), such as
IP cameras, wireless access points, and IP phones. The 24 to 110 VDC wide power
input range and isolated dual power inputs not only allow you to use the same
type of power source at different sites around the globe, but also increase the
reliability of your communications system. Furthermore, the -40 to 70∞C
operating temperature range of the switches ensures they can withstand
deployment in harsh environments. TN-4500A Series Ethernet switches are
compliant with the mandatory sections of EN 50155, covering operating
temperature, power input voltage, surge, ESD, and vibration, as well as
conformal coating and power insulation, making the switches suitable for a
variety of industrial applications.
