The ITP-500/800 models are unmanaged, industrial grade, Fast Ethernet switches, with 5 or 8  10/100Base-TX Fast Ethernet ports. These unmanaged Ethernet switches are designed for industrial applications in harsh environments.  The Ethernet ports utilize M12 connectors to ensure water-tight, robust connections and guarantee reliable operation against environmental disturbances such as vibration and shock. These switches are compliant with EN50155, covering operating temperature, power input voltage, surge, ESD, vibration, and shock, thus making them suitable for industrial applications in vehicle, rolling stock and factory automation.
