Antaira’s Next-Generation M12 PoE IP67 Water Resistant Ethernet Switch Provides Ultra-Reliable Connectivity in Rolling Stock and Automation Applications
October 31, 2025
Antaira Technologies, LLC has announced the LNP-0500G-M12-67-T Gigabit PoE+ M12 unmanaged five-port industrial switch. By combining unparalleled reliability, Power over Ethernet (802.3af/at), and certification to EN 50155 international standards, the new switch is optimized for uninterrupted connectivity in rolling stock or moving vehicles, as well as to accelerate digital transformations and bring industrial automation networks to peak performance.
“Day in and day out, Antaira industrial networking products perform under the rugged conditions, ensuring reliable operation while supporting your evolving digitalization demands,” said Joe Cook, General Manager, Antaira Technologies, LLC. “Our newest switch merges the innovation and dependability of Antaira industrial switches with a robust feature set specific to on-machine and rolling stock environments.”
Reliable to the Core
Critical industrial applications rely on the high reliability of network switches to deliver real-time data with maximizes network uptime. The ultra-reliable LNP-0500G-M12-67-T safeguards critical connectivity from vibration, dirt, humidity and dust by incorporating M12 X-coded connectors in four Gigabit PoE+ 30W ports, along with a single M12 A-coded port to supply DC low-voltage power to field devices. M12 connectors, resilient against heavy vibrations and shocks in rolling stock, robotic and automation, provide tighter, more secure connections than RJ45 designs found on standard switches.
In conjunction with the M12 connectors are an IP67-rated waterproof metal housing and a wide operating temperature range of -40° to 167° F that allows for decentralized installation outside of a control cabinet, while its fanless design minimizes risk of mechanical failures.
PoE+ Simplification
The LNP-0500G-M12-67-T brings a total PoE budget of up to 120W to PoE compatible devices like IP cameras, Wi-Fi access points, sensors, and digital signage, simplifying network infrastructures by consolidating power and data transmission through a single Ethernet cable.
Each of the switch’s four Gigabit ports supply up to 30W of power, making Antaira’s solution highly adaptable to the tight, limited spaces on trains and buses, or on-machine integrations. By reducing the need for separate power cabling, PoE also lowers the costs associated with switch installation and maintenance. Since power is delivered through the network cable, devices can be placed in optimal locations without being constrained by the availability of power outlets.
Compliance to Industry Standards
The LNP-0500G-M12-67-T meets the market-specific standards for multiple industrial approvals and certifications, including EN 50155 and EN 50121 for rolling stock. In addition, it is compliant with UL, CE, FCC, and IEC standards to ensure safe operation even under the harshest electromagnetic, climatic and mechanical conditions.
EN 50155 specifies requirements for electronic equipment on rolling stock, covering operating temperature, power input voltage, surge, ESD, and vibration.
