Harting expands preLink connector family with robust M12 moduleHarting is expanding its connector family based on Ha-VIS preLink technology by adding a robust universal M12 connector housing designed to incorporate a range of connector modules.

New modules that can be used in the M12 housing include a D-coded version for 4-core data cables with transfer rates of up to 100Mbit/s or a variant with X-coding for 8-core data cables, suitable for applications at up to 10Gbit/s.

Among the special features of Harting’s preLink connection technology is a terminal block connected to the individual cores of the data cable via internal insulation displacement terminations which remain stable over time and are vibration-proof. The cable assembled in this way is attached securely to the connector by means of spring contacts fitted in the module, enabling stringent shock and vibration requirements such as those specified in the DIN EN 50155 railway standard to be met.

The module is also designed with a shielding spring which creates a reliable contact between the cable screening and the metallic M12 housing. A set of seals with a slotted design ensures additional security.
