TERZ NITE-XK Series
Unmanaged Industrial Ethernet Switches
M12 IP40
Fast Ethernet
- Flexible use with 24 VAC/VDC
- IP40 metal housing
- Ultra-compact, ruggedized design
- Inrush current limitation
- Temperature range -40 to +70°C
- DIN EN 50155 rail compliant
- Polarity protection
- PROFINET suitable
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.
