Transmitting maximum data rates in transport industry
The 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 end device and distribution point. The cable assemblies are available in multiple configurations and the packaging and cable printing can be individually customized.
As 8-pole, X-coded compact connectors in Cat.6A, the M12 from Telegärtner can transmit data rates of up to 10 Gbit/s 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.
Applications for STX M12x1 Connectors
The expansion of communication infrastructure in rail and vehicle applications is advancing to make the on-board 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 on board.
Besides the onboard applications for passengers, even more processes are being automated by the vehicle operators. So 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 the train manufacturers are obliged to constantly improve their communication network infrastructure in the vehicles so they can offer a working, safe and reliable network.
Components installed in vehicles are subject to high requirements due to the harsh environmental conditions. Passenger safety is always the highest priority and has to be taken into account when choosing the different materials. If a secure and continuous data transmission needs to be ensured, then the connectors used must meet the high mechanical requirements for railways and vehicles. To guarantee these points, different standards were defined specifically for the transport industry. Telegärtner's M12 components meet these standards and are therefore suitable for installation in transport applications.
DIN EN 45545 – Teil 2:
The bulk cable conforms to both standards EN 45545-2:2013 HL1- HL3 as well as DIN 5510-2 hazard level 1-4 and has been developed for high fi re protection requirements in railway applications.
The bulk cable also conforms to standard ECE R118.02, which defi nes the fire behaviour of components installed in buses. The cable thus meets the stringent requirements for ECE R118.02 cabling and is therefore ideally suited for installations in the passengers' area in buses.
The connectors have been tested in for mechanical strength, climatic and corrosive resistance, degree of protection and functionality in accordance to the two railway standards EN 50155 and IEC 61373. The tests included all components from Telegärtner's M12x1 connector series. The tests were performed by an external accredited test laboratory and confi rmed the corrosion resistance.

EN 50155 Pkt. 12.2.3, 12.2.4, 12.2.5, 12.2.9, 12.2.10
To evaluate the behaviour of the connectors in different climatic conditions, the connectors went through the climatic test procedure with cyclic stress in cold, heat and damp heat. After this, the connectors were tested for their insulation resistance and dielectric strength according to IEC 61076-2-101. Before, during and after the climatic stress no thermal defect or other changes were detected, confi rming the connector series has passed the tests.
The salt spray test was also successfully completed according to EN 50155 section 12.2.9 and as such the corrosion resistance can be confi rmed.
IEC 61373 Pkt. 8 und 9 und 10
As a further test for the connectors, a simulation for long-term use in railway vehicles was undertaken with the help of a vibration and shock test. With this test the quality of the contact between the pin and the cable core with regard to its applicability in rail vehicles could also be confi rmed. During the mechanical stress, the functionality of the connectors was guaranteed at all times and no interruptions were detected.
IEC 60529 Pkt. 10, 13.2, 13.4, 14.2
The test to verify the IP67 protection class was carried out according to the above-mentioned standard. This test confi rmed both touch protection and foreign body protection according to IP6X. The submergence test for IPX7 was carried out without any visual defects or water penetration.
