Unmanaged industrial Ethernet switches are for railways

Robust, unmanaged industrial Ethernet switches with M12 connectivity have been designed by TE Connectivity for use in railways and other forms of public transport. The switches are designed to enable faster and more reliable networks, says the company.

The switches conform to EN50155 and will help the digitalisation in railway drives to facilitate safe, reliable public transport. As transport systems introduce the internet of things (IoT) in mass transportation and as equipment data networks in rail grow faster than the rail market, the switches respond to the need for faster data speeds and increased network reliability. The switches provide the connection ports to CCTV cameras, passenger information systems, sensors, lighting and HVAC.

The switches include redundant input power and an optional bypass, and ensure that networks do not fail, even in harsh conditions. In the event of a power failure, the switch will transfer data to the next network node, enabling uninterrupted network performance together with increased safety, says TE.

There are several options for input voltage as well as Power over Ethernet (PoE), enabling both data and electrical power to pass through the same twisted pair Ethernet cable. The plug and play switches ensure easy network set-up, according to TE. For example, the elimination of discrete power cables reduces both component and installation costs.

The number of ports ranges between five and eight ports, depending on the switch model, all supporting M12 connectivity. The switches support data speeds of up to  one Gbit per second, claimed to provide future-proofing against network expansions in the short and medium-term. The switches comply with EN50155, the international standard covering electronics equipment used on rolling stock for railway applications.

TE Connectivity manufactures connectors and sensors. It has operated for over 75 years serving transportation, industrial applications, medical technology, energy, data communications, and the home markets. The company has 78,000 employees, including more than 7,000 engineers, with offices in nearly 150 countries.
