EMO Systems EMOSAFE EN-95 Gigabit Network Isolator
EMO Systems EMOSAFE EN-95 Gigabit Network Isolator interrupts the electrically conductive connection (wires and shield) between devices connected via copper-guided Ethernet cabling. The device suppresses the electrical noise and galvanically decoupled copper-based Ethernet connections. The isolators prevent equipotential bonding currents and protect connected devices and their users from transient overvoltages directly or inductively coupled into the network cable because of installation errors, lightning, switching operations, or electrostatic discharges.
The EMOSAFE EN-95 is characterized by high Ethernet performance and very high dielectric strengths. The EN-95 is equipped with a TVS diode array on each conductor providing dielectric isolation of 5.6kVDC/4.0kVAC and ESD protection. Differential voltage peaks can be caused by malfunctions of connected devices or by electrostatic discharges during the plugging process. The network isolator passes high-frequency alternating signals according to the principle of electromagnetic induction in the frequency range used for data transmission. Because of this transmission principle, the EMO Systems EMOSAFE EN-95 Gigabit Network Isolator does not require its own power supply, and driver installation is not required.
This high-performance device introduces extremely low insertion losses and features robust M12 connectors commonly used in industrial applications for Ethernet applications. Systems designed around the EMO Systems EMOSAFE EN-95 can obtain ISO 11801 Class D ratings. Designed to meet the requirements of DIN EN 50155, this network isolator is suitable for use in railway vehicle construction and general industrial environments. Sockets and DIN rails adapters are available as accessories.
