TERZ NITE-XK Series

With minimal housing size and low power consumption, the NITE-XK Industrial Ethernet switches are the perfect link in harsh environments. By shock and vibration-proof M12 connection technology for data and power supply, all applications in harsh industrial environments and in rail and commercial vehicles can be networked. The redundant 24 Volt AC/DC power supply is protected against polarity reversal and works reliably even with undersupply of 9 VDC. The tolerance to voltage dips, a dielectric strength of 2.25 kVDC and the limitation of the inrush enable a stable operation in all operating conditions. With two different frame forwarding/blocking variants (LLDP/PTCP), all applications are optimally supported.
