Moxa debuts new M12 shielded unmanaged Ethernet switches ─ onboard vehicle and railway industry certified

Taipei, Taiwan, July 7, 2009 — Moxa introduces a new series of ToughNet M12 shielded Ethernet switches. The ToughNet switches use D-code M12 connectors and are certified to provide an ideal future-proof solution for rolling stock and railway industries where electronics devices must be able to withstand tough conditions such as vibrations, shock, power supply voltage variations, and EMI interference. Designed to meet industry standards, the ToughNet series is EN 50155/50121-3-2/50121-4 and e-mark certified to ensure reliable operation under different power supply inputs and environmental disturbances.

The first to showcase in this series are the TN-5308 series products, which are 8-port industrial unmanaged M12 Ethernet switches. In addition to M12 connectors for robust connections, the TN-5308 series also supports a power supply with universal 12/24/36/48 VDC inputs (LV model) or 72/96/110 VDC inputs (MV model) to satisfy a broad range of power demands and make them ideal for universal applications. The compact and robust design of the series allows for DIN-Rail or panel mounting and the switches can be directly installed on machines at field sites without an enclosure; wiring cost can therefore be reduced. Furthermore, the TN-5308 series comes with a variety of rugged features such as wide operating temperature, fanless design, and IP40 protected metal housing for reliable operations in the presence of heavy duty applications.
