High-speed M12 connectors for transportation

Telegärtner’s range of connectors for railway and vehicle applications has been expanded with the introduction of a new product series.

An add-on to the previous M12 connector series, the new series contains M12x1 X-coded connectors as plug and socket versions which are suitable for connecting to cables with both solid and stranded conductors, as well as offering 360° shielding. This shielding ensures safe and reliable data transmission.

The range is completed with factory-made cable assemblies for connections between end device and end device, or between end device and distribution point. The cable assemblies are available in multiple configurations and the packaging and cable printing can be individually customised.

As 8-pole, X-coded compact connectors in Cat.6A, the M12 from Telegärtner can transmit data rates of up to 10 Gbps in accordance with IEC 61076-2-109:2014. Even in harsh environments, the high bandwidth is ensured by separating the four pairs with a cross shield (X-coding). Remote powering of end devices is also possible.

The expansion of communication infrastructure in rail and vehicle applications is advancing to make the onboard experience as comfortable and entertaining as possible for the passengers. In addition to real-time information about the train schedule, passengers want the flexibility to be able to work and surf the web onboard.

Besides the onboard applications for passengers, even more processes are being automated by the vehicle operators; for example, processes like security systems where the carriages will be monitored by IP cameras or traffic flows will be managed automatically by the individual trains. Therefore, train manufacturers are obliged to constantly improve their communication network infrastructure in the vehicles so they can offer a working, safe and reliable network.

The basic structure of the new Telegärtner connector with X-coding corresponds to the M12 system used worldwide. The robust M12x1 connector in Category 6A can be fitted on-site without any special tools. The assembly-friendly connector also features very good shield contacting and covers a wide range of wire diameters (0,9 to 1,6 mm) and cable diameters (5,5 to 9 mm).

For connecting an IP camera, the passenger information system in carriages or other applications where high data rates need to be transmitted, Telegärtner also offers factory-made Category 6A connecting cables. The M12x1 X-coded connecting cables guarantee transmission rates of up to 10 Gbps and are available in different configurations and length variants from stock.

The over-moulded connectors are tested to IP67 against particle and water ingress. The M12x1 X-coded connecting cables have an S/FTP 4x2xAWG24/19 structure and a jacket material specially developed for transport applications. The cables pass the high requirements for fire safety regulations in the transport industry.

The connecting cables are supplied with Telegärtner printing on each cable and in Telegärtner packaging. If required, the packaging and printing can be adjusted to meet the customer’s specific requirements. Other configurations and adaptor cables, such as X-coded to D-coded or A-coded, are available on request.
