Miniature connectors for mechanically demanding applications

Connectors employed in electronics act as an interface between two printed circuit boards and must therefore be able to bear high mechanical stress. This is precisely what HARTING has focused on in the development of the har-flex THR variants. These new connectors provide a miniaturised contact pitch of 1.27mm while also ensuring a stable connection to the PCB.

THR stands for ‘through hole reflow’ and describes the termination technology using binders attached laterally (soldering studs). This makes them well suited to demanding mechanical applications which previously required larger connectors. SMT signal contacts soldered onto the surface ensure continued flexible separation of the conductor tracks within the circuit board and makes them usable on both sides.

Finally, to help further increase versatility and cost effectiveness, the new har-flex THR variants make use of tape and reel packaging and reflow soldering to allow easy integration into automatic assembly processes.
