In 2012, the first CONEC SMT connector family M12x1 was launched in different versions. Then, as the next connector family in SMT & THR, size M8x1 followed in 2015, which is used in an increasing number of circuit boards due to its compact design.
As a result of the permanent growth of digital communication and the massive increase in data volumes, especially in the industry 4.0, it is necessary to ensure faster and broader transmission of information.
CONEC makes a step in this direction with the new X-coded connector family size M12x1 which is designed for data transmission according to standard CAT 6A.
Increasingly complex electronic assemblies require more and more compact circuit boards with surface-mounted components which can be automatically equipped and thus contribute to cost optimization.
M12x1 X coded was designed for 10 GB/s data transmission, SMT surface mounting and THR design. THR allows surface mounting as well as reflow process ability. This soldered version has the well-known stability of wave soldering.

The new sockets M12x1 meet the specific requirements of the market, because they:
• consist of two parts (separation of insulation body and socket housing)
• have a modular structure
• are available in SMT and THR technology
• are suitable for front panel mounting
• are available for different market-standardized mounting heights
• are designed for axial as well as for radial shield connection
The user can mount the board equipped with the insulation body in different socket geometries. CONEC sockets are suitable for combined mounting and ideal for designs where the M12x1 thread of the housing is directly moulded on, thus creating maximum design flexibility.
The already mentioned characteristic way of mounting it in different socket geometries is the proprietary main feature of this innovative connector. The atypical appearance of the insulation body without socket is very special compared to the former SMT/THR connectors!
The dual and symmetrical arrangement of the contact springs refines the previous shield concepts through an axial and radial connection to the socket side and is the result of the requirement of low-resistance shield transmission. The already positive experience of an axial shield connection in the M12x1 SMT socket of 2012 has been further optimised by a low-load radial shield connection for the board.
If, due to the ever-smaller construction space requirements, the user has to do without the radial or the axial socket connection, it is possible now to use only one of the two contact types.
Due to the radial shield concept, a considerable tolerance range can be compensated during installation without negative effects on the contact resistances. Electromagnetic separation of the four pairs of wires according to CAT 6A is still 100%.
Another benefit is the flexible contact placement type with the mating connector. It can ensure electromagnetic separation of the pairs of wire by means of a massive shield body or suspended counter elements. Simultaneous overlapping and touching of the elements results in excellent shield transmission between two connectors.
Automated assembly of the connector is still possible, even with the spring elements. The board assembler can rely on a suction system and use the adhesive pad applied by CONEC to grasp the connector for the assembly.
